RESUMO
HEALTH CARE ORGANIZATION FOR 2024 OLYMPICS AND PARALYMPICS GAMES. The 2024 olympic and paralympic Games (JOP 2024) constitute the largest global festive event. While this major international gathering is primarily synonymous with celebrations, health security represents a major challenge for the French healthcare system in a highly tense national and international context. The health security of the JOP 2024 relies on close collaboration between the medical service of the organizer Paris 2024, responsible for care at the Olympic sites, and state services (SAMU, Law Enforcement, Firefighters) providing support in the event of serious health incidents or exceptional health situations (SSE). The projected impact on our healthcare structures (excluding SSE) appears moderate, as a 5% increase in hospital activity and approximately 150 additional daily emergencies are expected during the Olympic period compared to a normal summer season. In the event of a major incident resulting in a large number of casualties, state services will take over the governance of relief efforts by activating the ORSEC-NOVI and ORSAN-AMAVI plans for health response. The preparation of this health coverage involves an unprecedented mobilization of all healthcare stakeholders and is manifested by the organization of exercises at a very brisk pace.
ORGANISATION DU SYSTÈME DE SOINS POUR LES JEUX OLYMPIQUES ET PARALYMPIQUES 2024. Les Jeux olympiques et paralympiques 2024 (JOP 2024) constituent le plus important événement festif mondial. Si ce grand rassemblement international se veut avant tout synonyme de fête, la sécurité sanitaire représente un enjeu majeur pour le système de soins français, dans un contexte national et international en tension majeure. La sécurité sanitaire des JOP 2024 relève d'une étroite collaboration entre le service médical de l'organisateur Paris 2024, responsable des soins sur les sites olympiques, et les services de l'État (Samu, forces de l'ordre, sapeurs-pompiers) venant en soutien en cas d'événements sanitaires graves ou en cas de situation sanitaire exceptionnelle. La prévision de l'impact sur les structures sanitaires (en dehors de situation sanitaire exceptionnelle) semble modérée, puisque l'on attend une augmentation de 5 % de l'activité hospitalière et environ 150 urgences journalières de plus pendant la période olympique par rapport à une saison estivale normale. En cas d'événement majeur générant un grand nombre de victimes, les services de l'État prendront la gouvernance des secours par le déclenchement des plans ORSECNOVI et ORSAN-AMAVI pour la valence sanitaire. La préparation de cette couverture sanitaire fait appel à une mobilisation sans précédent de tous les acteurs de santé et se concrétise par l'organisation d'exercices à un r ythme très soutenu.

INTRODUCTION: Obtaining vascular access is crucial in critically ill patients. The EZ-IO® device is easy to use and has a high insertion success rate. Therefore, the use of intraosseous vascular access (IOVA) has gradually increased. AIM: We aim to determine how IOVA was integrated into management of vascular access during out-of-hospital cardiac arrest (OHCA) resuscitation. METHODS: Analysing the data from the OHCA French registry for events occurring between 1 January 2013 and 15 March 2021, we studied: demography, circumstances of occurrence and management including vascular access, delays and evolution. The primary outcome was the rate of IOVA implantation. RESULTS: Among the 7156 OHCA included in the registry, we analysed the 3964 (55%) who received cardiopulmonary resuscitation. The vascular access was peripheral in 3122 (79%) cases, intraosseous in 775 (20%) cases and central in 12 (<1%) cases. The use of IOVA has increased linearly (R2 = 0.61) during the 33 successive trimesters studied representing 7% of all vascular access in 2013 and 33% in 2021 (p = 0.001). It was significantly more frequent in traumatic cardiac arrest: 12% versus 5%; p < 0.0001. The first epinephrine bolus occurred significantly later in the IOVA group, at 6 (4-10) versus 5 (3-8) min; p < 0.0001. Survival rate in the IOVA group was significantly lower, at 1% versus 7%; p < 0.0001. CONCLUSION: The insertion rate of IOVA significantly increased over the studied period, to reach 30% of all vascular access in the management OHCA patients. The place of the intraosseous route in the strategy of venous access during the management of prehospital cardiac arrest has yet to be determined.
RESUMO
BACKGROUND: Epinephrine increases the chances of return of spontaneous circulation (ROSC) in out-of-hospital cardiac arrest (OHCA), especially when the initial rhythm is non-shockable. However, this drug could also worsen the post-resuscitation syndrome (PRS). We assessed the association between epinephrine use during cardiopulmonary resuscitation (CPR) and subsequent intensive care unit (ICU) mortality in patients with ROSC after non-shockable OHCA. METHODS: We used data prospectively collected in the Sudden Death Expertise Center (SDEC) registry (capturing OHCA data located in the Greater Paris area, France) between May 2011 and December 2021. All adults with ROSC after medical, cardiac and non-cardiac causes, non-shockable OHCA admitted to an ICU were included. The mode of death in the ICU was categorized as cardiocirculatory, neurological, or other. RESULTS: Of the 2,792 patients analyzed, there were 242 (8.7%) survivors at hospital discharge, 1,004 (35.9%) deaths from cardiocirculatory causes, 1,233 (44.2%) deaths from neurological causes, and 313 (11.2%) deaths from other etiologies. The cardiocirculatory death group received more epinephrine (4.6 ± 3.8 mg versus 1.7 ± 2.8 mg, 3.2 ± 2.6 mg, and 3.5 ± 3.6 mg for survivors, neurological deaths, and other deaths, respectively; p < 0.001). The proportion of cardiocirculatory death increased linearly (R2 = 0.92, p < 0.001) with cumulative epinephrine doses during CPR (17.7% in subjects who did not receive epinephrine and 62.5% in those who received > 10 mg). In multivariable analysis, a cumulative dose of epinephrine was strongly associated with cardiocirculatory death (adjusted odds ratio of 3.45, 95% CI [2.01-5.92] for 1 mg of epinephrine; 12.28, 95% CI [7.52-20.06] for 2-5 mg; and 23.71, 95% CI [11.02-50.97] for > 5 mg; reference 0 mg; population reference: alive at hospital discharge), even after adjustment on duration of resuscitation. The other modes of death (neurological and other causes) were also associated with epinephrine use, but to a lesser extent. CONCLUSIONS: In non-shockable OHCA with ROSC, the dose of epinephrine used during CPR is strongly associated with early cardiocirculatory death. Further clinical studies aimed at limiting the dose of epinephrine during CPR seem warranted. Moreover, strategies for the prevention and management of PRS should take this dose of epinephrine into consideration for future trials.

Importance: Tracheal intubation is recommended for coma patients and those with severe brain injury, but its use in patients with decreased levels of consciousness from acute poisoning is uncertain. Objective: To determine the effect of intubation withholding vs routine practice on clinical outcomes of comatose patients with acute poisoning and a Glasgow Coma Scale score less than 9. Design, Setting, and Participants: This was a multicenter, randomized trial conducted in 20 emergency departments and 1 intensive care unit (ICU) that included comatose patients with suspected acute poisoning and a Glasgow Coma Scale score less than 9 in France between May 16, 2021, and April 12, 2023, and followed up until May 12, 2023. Intervention: Patients were randomized to undergo conservative airway strategy of intubation withholding vs routine practice. Main Outcomes and Measures: The primary outcome was a hierarchical composite end point of in-hospital death, length of ICU stay, and length of hospital stay. Key secondary outcomes included adverse events resulting from intubation as well as pneumonia within 48 hours. Results: Among the 225 included patients (mean age, 33 years; 38% female), 116 were in the intervention group and 109 in the control group, with respective proportions of intubations of 16% and 58%. No patients died during the in-hospital stay. There was a significant clinical benefit for the primary end point in the intervention group, with a win ratio of 1.85 (95% CI, 1.33 to 2.58). In the intervention group, there was a lower proportion with any adverse event (6% vs 14.7%; absolute risk difference, 8.6% [95% CI, -16.6% to -0.7%]) compared with the control group, and pneumonia occurred in 8 (6.9%) and 16 (14.7%) patients, respectively (absolute risk difference, -7.8% [95% CI, -15.9% to 0.3%]). Conclusions and Relevance: Among comatose patients with suspected acute poisoning, a conservative strategy of withholding intubation was associated with a greater clinical benefit for the composite end point of in-hospital death, length of ICU stay, and length of hospital stay. Trial Registration: ClinicalTrials.gov Identifier: NCT04653597.

BACKGROUND: In cardiac arrest (CA), time is directly predictive of patients' prognosis. The increase in mortality resulting from delayed cardiopulmonary resuscitation has been quantified minute by minute. Times reported in CA management studies could reflect a timestamping bias referred to as "digit preference". This phenomenon leads to a preference for certain numerical values (such as 2, 5, or 10) over others (such as 13). Our objective was to investigate whether or not digit preference phenomenon could be observed in reported times of the day related to CA management, as noted in a national registry. METHODS: We analyzed data from the French National Electronic Registry of Cardiac Arrests. We analyzed twelve times-of-the-day corresponding to each of the main steps of CA management reported by the emergency physicians who managed the patients in prehospital settings. We postulated that if CA occurred at random times throughout the day, then we could expect to see events related to CA management occurring at a similar rate each minute of each hour of the day, at a fraction of 1/60. We compared the fraction of times reported as multiples of 15 (0, 15, 30, and 45 - on the hour, quarters, half hour) with the expected fraction of 4/60 (i.e. 4 × 1/60). MAIN RESULTS: A total of 47,211 times-of-the-day in relation to 6131 CA were analyzed. The most overrepresented numbers were: 0, with 3737 occurrences (8% vs 2% expected, p < 0.0001) and 30, with 2807 occurrences (6% vs 2% expected, p < 0.0001). Times-of-the-day as multiples of 15 were overrepresented (22% vs 7% expected, p < 0.0001). CONCLUSION: Prospectively collected times were considerably influenced by digit preference phenomenon. Studies that are not based on automatic time recordings and that have not evaluated and considered this bias should be interpretated with caution.

Background: In 2016, three European scientific societies called for standardization to the "2222" as a European unique phone number in case of in-hospital emergencies. This study describes the management of in-hospital emergency calls in all French military training hospitals and aims to detail their original transition, for the first time in France, to the "2222". Methods: An electronic standardized questionnaire was emailed to heads of rapid response teams in the eight French military training hospitals. Results: All participants answered the questionnaire (100%). The eight French military training hospitals had a specific procedure for management of in-hospital emergencies. Six hospitals already used a unique phone number for in-hospital emergencies, but none of them were using the 2222 in March 2019. Two hospitals still used several phone numbers for in-hospital emergencies, mainly due to historical and local arrangements. Rapid response teams included at least a physician and a nurse. There was a discussion to switch to "2222" as the unique phone number for in-hospital emergencies in two hospitals. In both, the discussions involved hospital executive officers, medical teams, rapid response teams and technical teams leading to a step-by-step transition. Finally, in October 2019, these two hospitals launched the "2222" procedure for in-hospital emergencies. Conclusion: This study found a large disparity in the eight French military training hospitals, concerning in-hospital emergency protocols. Two French military training hospitals launched the "2222" procedure for the first time in France. Further efforts are still needed to continue to promote the use of the 2222 as a European unique phone number for in-hospital emergencies.
RESUMO
The Incidence of peri-intubation cardiac arrest (PICA) has been rarely assessed in the out-of-hospital setting. The objectives of this study were to assess the incidence and factors associated with PICA (cardiac arrest occurring within 15 min of intubation) in an out-of-hospital emergency setting, wherein emergency physicians perform standardized airway management using a rapid sequence intubation technique in adult patients. This was a secondary analysis of the "Succinylcholine versus Rocuronium for out-of-hospital emergency intubation" (CURASMUR) trial, which compared the first attempt intubation success rate between succinylcholine and rocuronium in adult patients requiring emergency tracheal intubation for any vital distress except cardiac arrest. Enrollment occurred from January 2014 to August 2016 in 17 French out-of-hospital emergency medical units. All operators were emergency physicians. The PICA incidence was recorded and multivariable logistic regression analysis was used to identify the factors associated with its occurrence. A total of 1226 patients were included with a mean age of 55.9 ± 19 years. PICA was recorded in 35 (2.8%) patients. Multivariable analysis indicated that the occurrence of PICA was independently associated with a body mass index (BMI) > 30 kg m2 [adjusted odds ratio (aOR) 4.85; 95% confidence interval (CI) 1.82-12.90, p = 0.02], oxygen saturation (SpO2) before intubation < 90% (aOR 3.4; 95% CI 1.50-7.60, p = 0.003), difficult intubation (defined by an Intubation Difficulty Score [IDS] > 5, [aOR 3.59; 95% CI 1.82-8.08, p = 0.02], the use of rocuronium instead of succinylcholine (aOR 2.47; 95% CI 1.08-5.64, p = 0.03), post intubation hypoxaemia (aOR 2.70; 95% CI 1.05-6.95, p = 0.04), post-intubation hypotension (aOR 4.07; 95% CI 1.62-10.22, p = 0.003), and pulmonary aspiration(aOR 4.78; 95% CI 1.48-15.36, p = 0.009). Early PICA occurred in approximately 3% of cases in the out-of-hospital setting. We identified several independent risk factors for PICA, including obesity, hypoxaemia before intubation and difficult intubation.

Objectives: The objectives of this study were to evaluate first attempt intubation failure rate, its associated factors, and its related complications in out-of-hospital emergency setting, when emergency physicians perform standardized airway management using rapid sequence intubation in adult patients. Material and methods: The present study was a substudy of the Succinylcholine versus Rocuronium for out-of-hospital Emergency Intubation (CURASMUR) Trial, which compared Succinylcholine and Rocuronium used for Rapid sequence intubation. First attempt Intubation failure rate and early intubation related complications were recorded. We used multivariable logistic regression analysis to determine first intubation failure associated factors. Results: A total of 1230 patients were included with mean age of 55.9 +/- 19 years. First attempt intubation failure was recorded in 285 (23.2%) patients. The occurrence of a first attempt intubation failure was independently associated with history of ear, nose, and throat neoplasia (OR 2.20, CI 95% 1.06-4.60). Early intubation related complications were more frequent in case of first attempt intubation failure: 80 of 285 (28.4%) in patients with first attempt intubation failure and 185 of 945 (19.6%) in patients with successful first attempt intubation [OR 1.44; CI 95%, 1.11-1.87]. Conclusion: Based on a large multicenter study on out-of-hospital tracheal intubation of adult patients, we found that first attempt intubation failure rate was high and that history of ear, nose, and throat (ENT) neoplasia was an independent associated factor. Failure in first intubation attempt was associated with significantly more intubation related complications.

BACKGROUND: In out-of-hospital cardiac arrest (OHCA), bystander initiated cardiopulmonary resuscitation (CPR) increases the chance of return of spontaneous circulation and survival with a favourable neurological status. Socioeconomic disparities have been highlighted in OHCA field. In areas with the lowest average socioeconomic status, OHCA incidence increased, and bystander CPR decreased. Evaluations were performed on restricted geographical area, and European evaluation is lacking. We aimed to analyse, at a national level, the impact of area-level social deprivation on the initiation of CPR in case of a witnessed OHCA. METHODS: We included all witnessed OHCA cases with age over 18 years from July 2011 to July 2018 form the OHCA French national registry. We excluded OHCA occurred in front of rescue teams or in nursing home, and patients with incomplete address or partial geocoding. We collected data from context, bystander and patient. The area-level social deprivation was estimated by the French version of the European Deprivation Index (in quintile) associated with the place where OHCA occurred. We assessed the associations between Utstein variables and social deprivation level using a mixed-effect logit model with bystander-initiated CPR. RESULTS: We included 23,979 witnessed OHCA of which 12,299 (51%) had a bystander-initiated CPR. More than one third of the OHCA (8,326 (35%)) occurred in an area from the highest quintile of social deprivation. The higher the area-level deprivation, the less the proportion of bystander-initiated CPR (56% in Quintile 1 versus 48% in Quintile 5). The In the multivariable analysis, bystander less often began CPR in areas with the highest deprivation level, compared to those with the lowest deprivation level (OR=0.69, IC95%: 0.63-0.75). CONCLUSIONS: The level of social deprivation of the area where OHCA occurred was associated with bystander-initiated CPR. It decreased in the more deprived areas although these areas also concentrate more younger patients.

BACKGROUND: The individual factors associated to Frequent Users (FUs) in Emergency Departments are well known. However, the characteristics of their geographical distribution and how territorial specificities are associated and intertwined with ED use are limited. Investigating healthcare use and territorial factors would help targeting local health policies. We aim at describing the geographical distribution of ED's FUs within the Paris region. METHODS: We performed a retrospective analysis of all ED visits in the Paris region in 2015. Data were collected from the universal health insurance's claims database. Frequent Users (FUs) were defined as having visited ≥3 times any ED of the region over the period. We assessed the FUs rate in each geographical unit (GU) and assessed correlations between FUs rate and socio-demographics and economic characteristics of GUs. We also performed a multidimensional analysis and a principal component analysis to identify a typology of territories to describe and target the FUs phenomenon. RESULTS: FUs accounted for 278,687 (11.7%) of the 2,382,802 patients who visited the ED, living in 232 GUs. In the region, median FUs rate in each GU was 11.0% [interquartile range: 9.5-12.5]. High FUs rate was correlated to the territorial markers of social deprivation. Three different categories of GU were identified with different profiles of healthcare providers densities. CONCLUSION: FUs rate varies between territories and is correlated to territorial markers of social deprivation. Targeted public policies should focus on disadvantaged territories.

OBJECTIVES: To determine the efficacy of emergency medical center physicians' use of a protocol to guide their management of telephone consultations for fever and gastroenteritis. MATERIAL AND METHODS: Cluster randomized controlled trial. Participating centers were randomized to use the telephone protocol or provide usual telephone assistance. Six emergency centers in France included calls from patients needing advice on fever or gastroenteritis. Centers assigned to the protocol followed specific guidelines on managing the call and giving advice on treatment. Primary endpoints were the number of in-person visits and hospital admissions required within 15 days of the call. Secondary endpoints were patient satisfaction and costs. RESULTS: A total of 2498 calls were included. Use of the assigned protocol while attending 1234 calls was associated with a relative risk for hospitalization or an unscheduled in-person visit for care of 0.70 (95% CI, 0.58-0.85) versus usual practice. Ambulance use, admission to an intensive care unit, mortality, morbidity, and symptom improvement did not differ significantly between centers using the protocol and those following usual practice. Ninety percent of the patients were satisfied. The cost of care was 91 in centers applying the protocol and 150 in the other centers (P .01). CONCLUSION: Use of the protocol was associated with fewer unscheduled in-person visits for care and fewer hospital admissions. The protocol is safe and less costly than the centers' usual approaches to giving telephone advice.
OBJETIVO: Determinar la eficacia de un protocolo de asesoramiento médico telefónico formalizado (AMTF), realizado por un médico para consultas, para fiebre o gastroenteritis en centros de comunicación médica de emergencia. METODO: Ensayo clínico por conglomerado, controlado. Los pacientes fueron aleatorizados al grupo AMTF o al grupo de atención habitual. Participaron 6 centros de comunicación médica de emergencia franceses. Se incluyeron pacientes que solicitaban asistencia telefónica por fiebre o gastroenteritis. El grupo ATMF realizó recomendaciones protocolizadas sobre el manejo terapéutico. Se valoró el número de consultas presenciales o ingreso hospitalario durante los 15 días siguientes a la consulta. También se evaluó la satisfacción del paciente y el coste económico. RESULTADOS: Se incluyeron 2.498 llamadas. El grupo ATMF (n = 1.234) tuvo un riesgo relativo de 0,70 (CI 95% 0,58 a 0,85) de requerir un ingreso hospitalario o de realizar una consulta no programada durante el seguimiento. No hubo diferencias entre los dos grupos en cuanto al uso de ambulancia, el ingreso en cuidados intensivos, la mortalidad o morbilidad y la mejoría de los síntomas. La satisfacción de los pacientes fue del 90%. El coste total fue de 91 euros en el grupo de la ATMF y de 150 euros en el grupo de atención habitual (p 0,01). CONCLUSIONES: El grupo ATMF se asoció con una disminución de las consultas presenciales no programadas o del ingreso en el hospital. Este procedimiento es seguro y comporta un menor coste que la atención que se realiza habitualmente en la actualidad.

There is an urgent need for specific antiviral treatments directed against SARS-CoV-2 to prevent the most severe forms of COVID-19. By drug repurposing, affordable therapeutics could be supplied worldwide in the present pandemic context. Targeting the nucleoprotein N of the SARS-CoV-2 coronavirus could be a strategy to impede viral replication and possibly other essential functions associated with viral N. The antiviral properties of naproxen, a non-steroidal anti-inflammatory drug (NSAID) that was previously demonstrated to be active against Influenza A virus, were evaluated against SARS-CoV-2. Intrinsic fluorescence spectroscopy, fluorescence anisotropy, and dynamic light scattering assays demonstrated naproxen binding to the nucleoprotein of SARS-Cov-2 as predicted by molecular modeling. Naproxen impeded recombinant N oligomerization and inhibited viral replication in infected cells. In VeroE6 cells and reconstituted human primary respiratory epithelium models of SARS-CoV-2 infection, naproxen specifically inhibited viral replication and protected the bronchial epithelia against SARS-CoV-2-induced damage. No inhibition of viral replication was observed with paracetamol or the COX-2 inhibitor celecoxib. Thus, among the NSAID tested, only naproxen combined antiviral and anti-inflammatory properties. Naproxen addition to the standard of care could be beneficial in a clinical setting, as tested in an ongoing clinical study.

BACKGROUND: Significant improvements in survival from out-of-hospital cardiac arrest (OHCA) have been reported; however, these are based only on data from OHCA in whom resuscitation is initiated by emergency medical services (EMS). We aimed to assess the characteristics and temporal trends of OHCA without resuscitation attempt by EMS. METHODS: Prospective population-based study between 2011 and 2016 in the Greater Paris area (6.7 million inhabitants). All cases of OHCA were included in collaboration with EMS units, 48 different hospitals, and forensic units. RESULTS: Among 15 207 OHCA (mean age 70.7±16.9 years, 61.6% male), 5486 (36.1%) had no resuscitation attempt by EMS. Factors that were independently associated with increase in likelihood of no resuscitation attempt included: age of patients (odds ratio, 1.06 per year [95% CI, 1.05-1.06], P<0.001), female sex (odds ratio, 1.21 [95% CI, 1.10-1.32], P=0.002), OHCA at home location (odds ratio, 3.38 [95%CI, 2.86-4.01], P<0.001), and absence of bystander (odds ratio, 1.94 [95% CI, 1.74-2.16], P<0.001). Overall, the annual number of OHCA increased by 9.1% (from 2923 to 3189, P=0.028). This increase was related to an increase of the annual number of OHCA without resuscitation attempt by EMS by 26.3% (from 993 to 1253, P=0.012), while the annual number of OHCA with resuscitation attempt by EMS did not significantly change (from 1930 to 1936, P=0.416). Considering only cases with resuscitation attempt, survival rate at hospital discharge increased (from 7.3% to 9.5%, P=0.02). However, when considering all OHCA, survival improvement did not reach statistical significance (from 4.8% to 5.7%, P=0.17). CONCLUSIONS: We demonstrated an increase of the total number of OHCA related to an increase of the number of OHCA without resuscitation attempt by EMS. This increasing proportion of OHCA without resuscitation attempt attenuates improvement in survival rates achieved in EMS-treated patients.

INTRODUCTION: Chest compressions are the cornerstone of cardiopulmonary resuscitation. The recent International Liaison Committee on Resuscitation guidelines recommend increasing the rate and the depth of chest compressions, to 100-120/min and 5-6 cm, based on theoretical arguments and observational studies. We hypothesized that an increased chest compressions rate could decrease chest compressions depth. METHODS: Operators were asked to perform continuous chest compressions on a mannequin. Chest compressions rate and depth were collected. The ratio of chest compressions compliance to the guidelines, that is rate 100-120/min and depth 5-6 cm, was calculated. RESULTS: In total 951 sequences of chest compressions were studied. Median chest compressions rate: 114 (104-130)/min. Median chest compressions depth: 4.5 (3.4-5.3) cm. Correlation between rate and depth: low (R2 = 0.12). Chest compressions in compliance with the recommended rate: 434 (46%). Rate >120/min in 285 (30%) cases and <100/min in 223 (23%) cases. Chest compressions in compliance with the recommended depth: 286 (30%). Depth >6 cm in 50 (5%) cases and <5 cm in 621 (65%) cases. Finally, chest compressions were in compliance with the guidelines for both rate and depth in 141 (15%) cases. The ratio of chest compressions in compliance with the recommended depth significantly decreased with the increase of the rate: 40% for a rate <100/min, 32% for a rate in the target (100-120/min) and 18% for a rate >100/min (P < 0.0001). DISCUSSION: The ratio of chest compressions in compliance with the recommended rate and depth was as low as 15%. The rate of chest compressions in compliance with the recommended depth significantly decreased when the chest compressions rate increased. To reach both recommended rate and depth seems illusive.
