ABSTRACT

Objective. To evaluate the effects of application of a manual on the improvement of alarms management in Intensive Care Units (ICU). Methods. This quasi-experimental study evaluated the effectiveness of the introduction into of a manual for alarm management and control in the ICU of a hospital in southeastern Iran. The intervention was a 4-hour workshop was on topics related to the adverse effects of alarms, standardization of ECG, oxygen saturation and blood pressure monitoring systems, and the use of ventilators and infusion pumps. Data were collected thorough 200 hours of observation of 60 ICU nurses (100 hours' pre-intervention and 100 hours' post-intervention). Response time, type of response, customization of alarm settings for each patient, the person responding to an alarm, and the cause of the alarm were analyzed. Alarms were classified into three types: false, true and technical. Results. The results showed a statistically significant difference between the pre- and post-intervention frequency of alarm types, frequency of monitoring parameters, customized monitoring settings for patients, and individuals who responded to alarms. The percentage of effective interventions was significantly higher for all parameters after the intervention (46.9%) than before the intervention (38.9%). Conclusion. The employment of a manual for management of alarms from electronic equipment in ICUs can increase the frequency of appropriate responses to alarms in these units.

ABSTRACT

The study assessed the Clinicopathological changes of Wistar rats exposed to municipal landfill gaseous particulate emissions. Four groups of Wistar rats were exposed to the different sites of landfill emission with use of filters for filtering landfill gaseous emission while the control group was not exposed. Performance of the animals was evaluated weekly, blood and lung, liver, kidney and heart tissues were taken for haematological and histopatholgical examinations. At the end of six weeks exposure, the peak weight was recorded as 108.96±0.45 of Group B as compared to 126.352±0.88 of the Control Group, as well as the decrease in the body weight of Group A-D compared to the Control Group. There was leucocytosis, lymphocytosis and neutrophilia in the rats that were exposed to landfill emission. There were pulmonary, hepatic, and renal lesions while the heart was spared. Changes were observed on the use of filters for filtering landfill gaseous emission. The 3M 6001 CN Gas Mask Carnister Cartridge which filters 50% of landfill emission together with black polythene nylon restricting external air into the filtered cage was not sufficient to reduce the effect of landfill gaseous emission at the end of the exposure period. The screening with PM2.5 material which filters 100% of PM2.5 emission was only able to screen PM2.5 emission but could not screen other landfill gaseous emission. This indicates that landfill gaseous emission is capable of inducing respiratory problems and tissue damage on dumpsite workers if there is sufficient and continuous exposure to landfill gaseous emissions. To prevent the hazard that may arose from dumpsite activities; gas nose mask respirator is recommended for an individual who works as scavengers and landfill workers before entering the dumpsite environment..

ABSTRACT

Abstract Objectives: to identify valid blood biomarkers to detect heart failure and kidney failure associated with kidney disease and hemodialysis Methods: systematic literature review conducted in August 2018 in the following: Web Of Science, PubMed, Scopus, Cinahal, Cochrane, Science Direct and Lilacs. The guiding question was: "What are the blood biomarkers used to detect heart failure and kidney failure?" A total of537 publications were found, 94 of these appeared more than once, 383 were excluded after reading titles and abstracts, 32 were excluded after reading the full texts, and 10 were excluded in the quantitative and qualitative synthesis. Results: 18 papers compose the final sample and report laboratory and imaging tests, instruments to assess the risk of kidney and heart failure, and also clinical management of the progression of kidney and heart failure. All the studies correlated risk of mortality and death outcome. Conclusion: laboratory tests are important to identifying kidney and heart failure and need to be used to improve clinical management of the hemodialysis treatment of people with chronic kidney disease in order to improve quality of life and life expectancy.

ABSTRACT

Abstract Objectives: to evaluate the modified early obstetric warning system (MEOWS) in women after pregnancies in a tertiary hospital in Brazil. Methods: a descriptive study was conducted with 705 hospitalized women. Vital signs (systolic and diastolic blood pressure, heart rate, respiratory rate, temperature) and lochia were registered on medical records and transcribed into the MEOWS chart of physiological parameters. On this graphic chart, yellow alerts were used to present moderate abnormalities in vital signs, while severe abnormalities were presented in red. The presence of at least one red alert or two yellow alerts were triggered to indicate the need for medical evaluation. Results: although abnormalities were found in the physiological parameters of 49.8% of the women identified from MEOWS triggers, medical evaluation was only requested for three patients (0.8%). Conclusions: in a retrospective application of the use of MEOWS showed a significant number of patients had triggered in which the nursing team did not recognize 99.2% of cases. This finding could be attributed to the fact that MEOWS has not been yet adopted in this service as part of the nursing care. The application of this tool would result in a better care because critical situations would be recognized and corrected quickly, avoiding unfavorable outcomes.


Resumo Objetivos: avaliar o modified early obstetric warning system (MEOWS) em mulheres após gestações, em um hospital terciário do Brasil. Métodos: foi realizado um estudo descritivo incluindo 705 mulheres internadas. Os sinais vitais (pressão arterial sistólica e diastólica, frequência cardíaca, frequência respiratória, temperatura) e lóquios, registrados no prontuário, foram transcritos para o gráfico de parâmetros fisiológicos do MEOWS. Neste gráfico, anormalidades moderadas nos sinais vitais eram sinalizadas por alertas amarelos, enquanto anormalidades graves eram sina-lizadas em vermelho. A presença de, pelo menos, um alerta vermelho ou dois alertas amarelos foi chamada de eventos gatilho, indicando necessidade de avaliação médica. Resultados: dentre as mulheres estudadas, 49,8% apresentaram anormalidades nos parâmetros fisiológicos, através da identificação de eventos gatilho no MEOWS, porém avaliação médica foi solicitada para apenas três pacientes, resultando num percentual de 0,8%. Conclusões: a utilização do MEOWS, de forma retrospectiva, evidenciou uma quantidade significativa de pacientes apresentando eventos gatilho, os quais não foram reconhecidos pela equipe de enfermagem em 99,2% dos casos. Este achado pode ser atribuído ao fato de o MEOWS ainda não ser adotado no serviço como parte da rotina dos cuidados de enfermagem. A aplicação dessa ferramenta resultaria numa assistência melhor, pois situações críticas seriam reconhecidas e corrigidas com maior precocidade, evitando desfechos desfavoráveis.

ABSTRACT

Introducción: El dengue es una enfermedad capaz de producir extravasación importante de plasma con hipovolemia y choque, signos frecuentes de gravedad y causa de muerte. Objetivo: Valorar la utilidad de la identificación de los signos de alarma en niños y adolescentes con dengue. Métodos: Estudio prospectivo de 110 pacientes (0-18 años de edad y de ambos sexos) quienes presentaron signos de alarma de dengue grave y se trataron con soluciones cristaloides por vía intravenosa durante su ingreso hospitalario y un número igual de pacientes que no tuvieron esos signos y no requirieron dicho tratamiento. Se aplicó retrospectivamente la clasificación de la OMS 2009 y se comparó con la precedente de1977. Resultados: Los signos de alarma encontrados con mayor frecuencia fueron: dolor abdominal intenso y mantenido (50 por ciento) y vómitos repetidos 3 o más en 4 horas (34,3 por ciento, que aparecieron durante el dia de la defervescencia en 46 por ciento de los pacientes y la mitad mostró ascitis. Después de seis horas de tratamiento con soluciones cristaloides por vía intravenosa, el porcentaje de pacientes con dolor abdominal disminuyó a 30 por ciento, y el de pacientes con signos de bajo gasto cardiaco (hipotensión) disminuyó de 30 a 10 por ciento. No hubo fallecidos. Conclusiones: Los signos alarma del dengue grave cuya identificación ha sido recomendada por OMS y OPS y tambien en las Guías Cubanas, tienen especial importancia en la atención de niños y adolescentes hospitalizados y demostrada su utilidad tanto en la prevencion del agravamiento como en la mejoria del cuadro grave cuando fue tratado en sus inicios(AU)


Introduction: Dengue is a disease that is capable of producing an important plasma extravasation with hypovolaemia and shock, which are frequent signs of seriousness and causes of death. Objective: To value the usefulness of warning signs identification in children and adolescents with dengue. Methods: A prospective study was carried out to 110 children (0-18 years old, both sexes) at Dr. Angel A. Aballi University Pediatric Hospital who had confirmed dengue´s warning signs and were admitted to the Intensive Care Unit and treated with crystalloids solutions by intravenous route. An equivalent number of confirmed dengue patients who did not have warning signs nor received that treatment were the control group. Clinical data and the results of laboratory tests were recorded since patients were admitted in the Intensive Care (ICU) and after 6 hours of treatment. The 2009 World Health Organization (WHO) Dengue Classification was used to classify patients retrospectively and a comparison was made with the WHO 1977 Dengue Classification. Results: Clinical warning signs that were more frequently identified were: intensive and continuous abdominal pain (50 percent) and frequent vomiting (3 or more in 4 hours) (34.3 percent) that appeared during defervescence (46 percent of patients), and half of them presented ascites. After 6 hours of treatment with the crystalloids solutions, the number of patients with abdominal pain decreased to 30 percent and those with low cardiac output (hypotension) from 35 percent to 10 percent. No fatalities occurred. Conclusions: Warning signs of severe dengue, which identification has been recommended by WHO and PAHO and also in the Cuban Guidelines, has special importance in the care of hospitalized children and adolescents; and it was demonstrated its usefulness in the prevention of severity as in the improvement of the signs of severity when those were treated in the onset period(AU)

ABSTRACT

ABSTRACT Objective: To measure the magnitude of the effect of an individualized parameterization protocol for hemodynamic alarms in patients with acute myocardial infarction. Method: Pragmatic clinical trial, open label and single arm, whose intervention was performed through a protocol validated and tested in 32 patients using multiparametric monitors. The heart rate, blood pressure, respiratory rate, oxygen saturation and ST segment-monitoring were measured and classified for clinical consistency one hour before and after the intervention, for 64 hours. Results: The protocol obtained Content Validity Index of 0.92. Of the 460 registered alarms, 261 were considered inconsistent before the intervention and 47 after it. The Relative Risk of inconsistent alarms after the protocol was 0.32 (95% CI 0.23-0.43, p <0.0001). Conclusion: The protocol proved to be a protective factor to the appearance of inconsistent clinical alarms of multiparametric monitors.

ABSTRACT

Abstract Objective: To evaluate and correlate, before and after the therapeutic intervention, the behavioral problem scores evaluated by the CBCL/6-18 questionnaire and the quality of life indexes evaluated by the PedsQL™ 4.0 in patients with monosymptomatic nocturnal enuresis. Method: After the initial evaluation and completion of the CBCL/6-18 questionnaire, a multidisciplinary evaluation and completion of the PedsQL™ 4.0 questionnaire was performed. Of the initially evaluated 140 children and adolescents aged 6-16 years, 58 were excluded due to non-monosymptomatic enuresis or associated comorbidities. Of the initially included 82 patients, who were randomized to three treatment groups, 59 completed the CBCL/6-18 and PedsQL™ 4.0 questionnaires at the end of the treatment and were included in this study. The α error was set at 5% for ruling out the null hypothesis. Results: Of the total of 59 participants, 45.8% responded with total success, 23.7% were partially successful, 23.7% did not reach the improvement criteria, and 6.8% gave up the treatment. There was a significant increase in quality of life indexes and a reduction of post-intervention behavioral problem scores, in the three proposed modalities, in patients who had a total or partial response to treatment. There was no correlation between higher scores of pre-treatment behavior problems and therapeutic failure. Conclusions: Only the participants who successfully responded to interventions showed improvement in quality of life and behavioral problems, which indicates that enuresis is a primary problem that has a negative impact on these parameters. The authors suggest that it is possible to achieve success in the treatment of monosymptomatic enuresis, even in patients with high pre-intervention behavioral problem scores.


Resumo Objetivo: Avaliar e relacionar, pré e pós-intervenção terapêutica, em pacientes com enurese noturna monossintomática, os escores de problemas de comportamento, avaliados pelo questionário CBCL/6-18, e os índices de qualidade de vida, avaliados pelo PedsQL™ 4.0. Método: Após avaliação inicial e preenchimento CBCL6/18, procedeu-se avaliação multidisciplinar e preenchimento do PedsQL™ 4.0. Das 140 crianças e adolescentes de 6 a 16 anos inicialmente avaliados, 58 foram excluídos por enurese não monossintomática ou comorbidades associadas. Dos 82 pacientes inicialmente incluídos e randomizados em três grupos de tratamento, 59 preencheram o CBCL/6-18 e PedsQL™ 4.0 no fim do tratamento e puderam ser incluídos neste trabalho. O erro alfa foi estabelecido em 5% para descarte da hipótese de nulidade. Resultados: Dos 59 participantes 45,8% responderam com sucesso total, 23,7% tiveram sucesso parcial, 23,7% não atingiram critério de melhoria e 6,8% desistiram do tratamento. Verificou-se aumento significativo dos índices de qualidade de vida e redução dos escores de problemas de comportamento pós-intervenção, nas três modalidades propostas, nos pacientes que obtiveram resposta total ou parcial ao tratamento. Não se demonstrou correlação entre maiores escores de problemas de comportamento pré-tratamento e insucesso terapêutico. Conclusões: Apenas os participantes que responderam com sucesso às intervenções melhoraram em sua qualidade de vida e problemas comportamentais, o que indica que a enurese é um problema primário que impacta negativamente esses parâmetros. Sugere-se que é viável obter sucesso no tratamento da enurese monossintomática, mesmo em pacientes com altos escores de problemas de comportamento pré-intervenção.

ABSTRACT

ABSTRACT Objective: To measure the response time of health professionals before sound alarm activation and the implications for patient safety. Method: This is a quantitative and observational research conducted in an Adult Intensive Care Unit of a teaching hospital. Three researchers conducted non-participant observations for seven hours. Data collection occurred simultaneously in 20 beds during the morning shift. When listening the alarm activation, the researchers turned on the stopwatches and recorded the motive, the response time and the professional conduct. During collection, the unit had 90% of beds occupied and teams were complete. Result: We verified that from the 103 equipment activated, 66.03% of alarms fatigued. Nursing was the professional category that most provided care (31.06%) and the multi-parameter monitor was the device that alarmed the most (66.09%). Conclusion: Results corroborate the absence or delay of the response of teams, suggesting that relevant alarms might have been underestimated, compromising patient safety.


RESUMEN Objetivo: Mensurar el tiempo-respuesta de los profesionales de salud delante del disparo de las alarmas sonoras, y las implicaciones para la seguridad del paciente. Método: Investigación cuantitativa, observacional, en una Unidad de Terapia Intensiva - Adulto de un hospital de enseñanza. Los tres investigadores han realizado observaciones no participativas durante 7 horas. La recogida de los datos ha ocurrido simultáneamente en 20 camillas en el período diurno. Al oír el disparo, los investigadores accionaban los cronómetros y registraban el motivo, el tiempo-respuesta y la conducta profesional. Durante la recogida, la unidad estaba con el 90% de las camillas ocupadas y los equipos estaban completados. Resultados: Certificamos que, de los 103 equipamientos que han sido disparados, el 66,03% de las alarmas han fatigado. La enfermería ha sido la categoría profesional que más ha atendido (el 31,06%), y el monitor multiparámetros ha alarmado (el 66,09%). Conclusión: Los resultados han corroborado la ausencia o el retardo de la respuesta del equipo, sugiriendo que las alarmas relevantes hayan sido menospreciadas, comprometiendo la seguridad de los pacientes.

ABSTRACT

Se realizó un estudio observacional, descriptivo y transversal en el Instituto de Medicina Tropical Pedro Kourí de La Habana, donde estuvieron ingresados 485 pacientes desde enero hasta diciembre de 2012 con diagnóstico de infección por dengue, de los cuales se escogió una muestra de 247. Entre los signos de alarma más comunes sobresalieron la cifra ascendente del hematocrito (54,6 por ciento y el dolor abdominal intenso o mantenido o de ambos tipos (46,1 por ciento . Las señales de alarma aparecieron por lo general al ceder la fiebre; del total de pacientes que las presentaron en algún momento de su evolución, 81,2 por ciento fueron tratados con hidratación intravenosa precoz y ninguno evolucionó hacia la forma grave de la enfermedad. La terapia hidratante parenteral se inició tardíamente en 18,8 por ciento de los afectados, incluidos todos aquellos en estado grave.


An observational, descriptive and cross sectional study was carried out in Pedro Kourí Tropical Medicine Institute from Havana, where 485 patients were admitted from January to December, 2012 with diagnosis of infection due to dengue fever, from whom a sample of 247 was chosen. Among the most common warning signs there were the increasing values of hematocrit (54.6 percent), and the intense or sustained abdominal pain or both types (46.1 percent). The warning signs generally appeared when fever ceased, and of the total of patients that presented it, 81.2 percent at some moment of their clinical course were treated with early intravenous hydration, and none developed the serious form of the disease. The parenteral hydration therapy began belatedly in 18.8 percent of the affected, including all those in severe state.

ABSTRACT

OBJETIVOS: caracterizar quais alarmes sonoros disparados por ventiladores mecânicos foram mais frequentes, descrever o tempo estímulo-resposta aos alarmes do ventilador mecânico e analisar as condutas dos profissionais de enfermagem diante dos alarmes ventilatórios. MÉTODO: pesquisa descritiva, quantitativa, realizada em uma unidade de terapia intensiva de um hospital universitário do Rio de Janeiro. Os dados foram tratados com estatística descritiva. RESULTADOS: realizadas 60 horas de observação, nesse período, soaram 25 alarmes de ventiladores mecânicos, 20 alarmes foram atendidos e 5 pararam sem nenhuma intervenção. Os alarmes mais prevalentes foram volume minuto expirado baixo, e pressão de vias aéreas alta. O tempo mínimo para atendimento dos alarmes foi 10 segundos, o tempo máximo 3 minutos, e o tempo médio 38 segundos. As condutas mais realizadas pelos profissionais de enfermagem foram aspiração traqueal, reposicionamento do circuito e ausculta pulmonar. CONCLUSÃO: os achados da pesquisa apontaram que, nos alarmes mais prevalentes, as condutas dos profissionais de enfermagem, de acordo com a literatura, não foram suficientes para a resolutividade dos problemas apresentados.


OBJECTIVES: to characterize which alarms were activated by mechanical ventilators were more frequent, to describe the stimulusresponse time to the mechanical ventilator alarms and to analyze the nursing professionals conducts before ventilatory alarms. METHOD: descriptive, quantitative research performed in an intensive care unit of a university hospital in Rio de Janeiro. The data were treated with descriptive statistics. RESULTS: 60 hours of observation were performed. During this period, 25 mechanical ventilator alarms sounded, 20 alarms were answered and 5 stopped without any intervention. The most prevalent alarms were low expired minute volume, and high airway pressure. The minimum time to answer the alarms was 10 seconds, the maximum time 3 minutes, and the average time 38 seconds. The most accomplished conducts by the nursing professionals were tracheal aspiration, circuit repositioning and pulmonary auscultation. CONCLUSION: the research findings pointed out that, in the most prevalent alarms, nursing professionals' conduct, according to the literature, was not enough to solve the problems presented.

ABSTRACT

With the improvement of the quality of clinical diagnosis and treatment, the traditional scheduled "ward round" mode cannot meet the demands for real-time monitoring of acute and critically ill patients. This paper introduces the Storm, a real-time data stream processing technology and its application in the real time disease early warning system. By collecting the clinical data flow and calculating the MEWS scores in real time, the system can identify the potential deterioration of the disease, and promptly notify the medical staff. Score calculation results can be stored for further analysis and presentation as well.

ABSTRACT

PURPOSE: This study aimed to investigate the clinical alarm occurrence and management of nurses toward clinical alarms in the intensive care unit (ICU). METHODS: This observational study was conducted with 40 patients and nurses cases in two ICUs of a university hospital. This study divided 24 hours into the unit of an hour and conducted two times of direct observation per unit hour for 48 hours targeting the medical devices applied to 40 patients. Data were analyzed using IBM SPSS Statistics 23. RESULTS: On average, 3.8 units of medical devices were applied for each patient and the ranges of alarm settings were wide. During 48 hours, 184 cases of clinical alarm were occurred by four types of medical devices including physiological monitors, mechanical ventilators, infusion pumps, and continuous renal replacement therapy. Among them, false alarm was 110 cases (59.8%). As for the alarm management by ICU nurses, two-minute alarm mute took up most at 38.0% (70 cases), and no response was second most at 32.6% (60 cases). When valid alarm sounded, nurses showed no response at 43.2%. CONCLUSION: The findings suggest that a standard protocol for alarm management should be developed for Korean ICU settings. Based on the protocol, continuous training and education should be provided to nurses for appropriate alarm management.

ABSTRACT

BACKGROUND: An automatic alarm system was developed was developed for unexpected vital sign instability in admitted patients to reduce staffing needs and costs related to rapid response teams. This was a pilot study of the automatic alarm system, the medical emergency system (MES), and the aim of this study was to determine the effectiveness of the MES before expanding this system to all departments. METHODS: This retrospective, observational study compared the performance of patients admitted to the pulmonary department at a single center using patient data from three 3-month periods (before implementation of the MES, December 2013–February 2014; after implementation of the MES, December 2014–February 2015 and December 2015–February 2016). RESULTS: A total of 571 patients were admitted to the pulmonary department during the three observation periods. During this pilot study, the MES automatically issued 568 alarms for 415 admitted patients. There was no significant difference in the rate of cardiopulmonary resuscitation (CPR) before and after application of the MES. The mortality rate also did not change. However, it appeared that CPR was prevented in four patients admitted from the general ward to the intensive care unit (ICU) during MES implementation. The median length of hospital stay and median length of ICU stay were not significantly different before and after MES implementation. CONCLUSIONS: Although we did not find a significant improvement in outcomes upon MES implementation, the CPR rate and mortality rate did not increase despite increased comorbidities. This was a small pilot study and, based on these results, we believe that the MES may have significant effects in longer-term and larger-scale studies.

ABSTRACT

PURPOSE: Insulin pumps are widely used in diabetes. They are equipped with safety alarms to alert users. Pump manuals contain alarm codes and how to troubleshoot them. However, these manuals are lengthy and difficult to use, particularly in emergencies. We aim to assess the impact of targeted education on warnings and errors in improving competency to troubleshoot the alarms. METHODS: Twenty-one patients, with a median age of 13, were recruited over a 5-month period. Each patient had 2 study visits. The frequencies and types of alarms were recorded, and patients were given a summary sheet that outlined common alarms encountered and troubleshooting tips. In visit 2, the frequencies and types of alarms were compared to those of visit 1. The patients were asked to fill a questionnaire and to rate the education session given in visit 1, their level of competency in decrypting alarm codes, and their promptness in responding to alarms. RESULTS: Low cartridge (W1), low battery (W2), and bolus cancelled (W8) were the commonest warnings. The most noted errors were occlusion (E4), power interruption (E8), empty battery (E2), set not primed (E11), and cartridge empty (E1). The numbers of warning and error signals markedly decreased after targeted education (P < 0.05). The ability in decrypting warning signals significantly improved (P=0.02), and the frequency of response to pump alarms significantly increased (P=0.001). CONCLUSION: Certain warnings and errors are more common than others in insulin pumps. Targeted education is useful in improving competency and response of patients in managing pump alarms.

ABSTRACT

RESUMO Problemas inerentes a usabilidade de Equipamento Médico-Assistencial (EMA) e segurança do paciente em Unidades de Cuidados Intensivos (UCI) vão além daqueles descritos entre as seis metas internacionais de segurança do paciente do National Institutes of Health (NIH). Os Ventiladores Mecânicos (VM) geram muitos alarmes sonoros, alguns com dados pouco consistentes. Objetivou-se analisar a usabilidade de alarmes sonoros disparados por VM em UCI. Pesquisa observacional descritiva, do tipo estudo de caso, com abordagem quantitativa, desenvolvida na UCI de um hospital universitário localizado no Rio de Janeiro. Os dados foram analisados com estatística descritiva. Durante 30 horas de observação, foram registrados 129 alarmes disparados pelo VM, dos quais, somente cinco tiveram resposta e 124 fatigaram. Frequência respiratória alta (n=31), seguida do alarme de volume corrente baixo (n=26), pressão de via aérea alta (n=24), pressão de via aérea baixa (n=23), desconexão de circuito (n=18) e alarme de FiO2 (n=7) foram os mais prevalentes. Apenas 36 foram classificados como consistentes. Conclui-se que os alarmes passaram a ser cada vez mais banalizados pela equipe nas UCI. É necessário mudar a postura diante deles e melhorar sua efetividade.

ABSTRACT Problems inherent in the usability of medical and healthcare equipment (MHE) and patient safety in intensive care units (ICU) go beyond those described among the six international goals patient safety from the National Institutes of Health (NIH). The mechanical ventilators (MV) generate many audible alarms, some with inconsistent data. The objective was to analyze the usability of audible alarms triggered by VM in ICU. Descriptive observational research, study case type with a quantitative approach, developed in the ICU of a university hospital located in Rio de Janeiro. Data were analyzed with descriptive statistics. During 30 hours of observation, 129 alarms triggered by MV were recorded, of which only 05 had a response and 124 fatigued. Respiratory high frequency (n=31), followed by low volume alarm (n=26), high airway pressure (n=24), low airway pressure (n=23), circuit disconnection (n=18), and alarm FiO2 (n=7) were the most prevalent. Only 36 were classified as consistent. The alarms have become increasingly trivialized by the team in the ICU. It is necessary to change the attitude towards them, improving their effectiveness.
