Analysis of the Nursing Effect of Respiratory Critical Illness Based on Refined Nursing Management.

In order to improve the nursing effect of respiratory critical illness, this paper combines the refined nursing method to explore the nursing plan of respiratory critical illness. Moreover, this paper uses the variable control method to explore the effects of nursing management, combines the hospital patient samples to conduct a controlled trial analysis, and conducts sample grouping according to the random grouping method. The patients in the control group are managed by traditional nursing management methods, the patients in the test group are managed by refined nursing management methods, and other conditions are basically the same. In addition, the experiment process variable control is carried out according to the mathematical statistics method, and the reasonable statistics and data processing are carried out. Through the comparison method, we can see that the refined management method proposed in this paper has a good effect in the nursing of respiratory critical illness.

Nasal cannula or high-flow oxygen for patients with COPD in acute respiratory distress?

ABSTRACT: There may be some confusion regarding the use of supplemental oxygen in patients with chronic obstructive pulmonary disease (COPD) who are experiencing acute respiratory distress. This article addresses a common nursing misconception regarding the use of high-flow oxygen administration via non-rebreather masks instead of low-flow oxygen administration via nasal cannulas in patients with COPD who are in acute respiratory distress, an issue that was investigated in a simulation education exercise and survey of the nursing staff at the authors' facility.

Prone Team: A Large-Scale Prone Position Initiative During COVID-19 Pandemic.

AIM: To identify strategies to improve time to prone in ICUs during the coronavirus disease 2019 (COVID-19) pandemic for patients meeting the criteria for prone position ventilation. BACKGROUND: Healthcare systems worldwide experienced an influx of COVID-19 patients, especially in critical care. COVID-19 patients are at risk of acute respiratory distress syndrome (ARDS). Prone position ventilation is the standard of care for mechanically ventilated patients with moderate to severe ARDS. Prone maneuvers in and of itself are time-consuming and labor-intensive, posing additional risks to patients. APPROACH: Our academic medical center developed a travel proning team to address the rapid increase in COVID-19 patients with ARDS necessitating prone positioning. EVALUATION: Over a period of 30 days, 420 ICU patients were intubated, 131 had moderate to severe ARDS and underwent prone positioning. Patients were placed in prone position or returned to supine position more than 834 times over 38 days. At the highest point, 37 procedures were done in 24 hours. CONCLUSION: This quality initiative demonstrated that utilization of a traveling proning team provides efficiency in time to prone. Developing a travel prone team allowed for efficiency in time to prone, supported the ICU clinical teams, and enhanced interdisciplinary collaboration, which is essential during times of crisis.

Nursing Management of Prone Positioning in Patients With COVID-19.

BACKGROUND: At the height of the coronavirus disease 2019 (COVID-19) pandemic, Italy had the highest number of deaths in Europe; most occurred in the Lombardy region. Up to 4% of patients with COVID-19 required admission to an intensive care unit because they developed a critical illness (eg, acute respiratory distress syndrome). Numerous patients with acute respiratory distress syndrome who had been admitted to the intensive care unit required rescue therapy like prone positioning. OBJECTIVE: To describe the respiratory management of and the extensive use of prone positioning in patients with COVID-19 at the intensive care unit hub in Lombardy, Italy. METHODS: A total of 89 patients (67% male; median age, 59 years [range, 23-80 years]) with confirmed COVID-19 who were admitted between February 23 and March 31, 2020, were enrolled in this quality improvement project. RESULTS: Endotracheal intubation was required in 86 patients (97%). Prone positioning was used as rescue therapy in 43 (48%) patients. Significantly more younger patients (age ≤ 59 years) were discharged alive (43 of 48 [90%]) than were older patients (age ≥ 60 years; 26 of 41 [63%]; P < .005). Among the 43 patients treated with prone ventilation, 15 (35% [95% CI, 21%-51%]) died in the intensive care unit, of which 10 (67%; P < .001) were older patients. CONCLUSIONS: Prone positioning is one strategy available for treating acute respiratory distress syndrome in patients with COVID-19. During this pandemic, prone positioning can be used extensively as rescue therapy, per a specific protocol, in intensive care units.

Critical Care Considerations in Adult Patients With Influenza-Induced ARDS.

TOPIC: Acute respiratory distress syndrome is a complex respiratory disease that can be induced by influenza virus infection. Critical care providers are uniquely positioned to manage this pathological progression in adult patients through evidence-based practice. CLINICAL RELEVANCE: Influenza and subsequent acute respiratory distress syndrome are associated with extremely high morbidity and mortality in adult patients in the United States. Although evidence-based medical management strategies can alter the clinical trajectory of acute respiratory distress syndrome and improve outcomes, critical care providers do not always implement these measures. PURPOSE: To provide critical care providers with an overview of the pathological progression of influenza-induced acute respiratory distress syndrome and the current evidence-based strategies for management. CONTENT COVERED: This article reviews the epidemiology and pathophysiology associated with influenza-induced acute respiratory distress syndrome, the criteria for diagnosis, and the evidence-based medical management.

Prone Position in Acute Respiratory Distress Syndrome Patients: A Retrospective Analysis of Complications.

BACKGROUND: Early application of prolonged prone positioning has been shown to improve patient survival in moderate to severe adult respiratory distress syndrome (ARDS) patients. Prone position is a key component of lung protective mechanical ventilation in association with low tidal volume and neuromuscular blocking agents in patients with severe ARDS. Pressure sores are the major prone position complication. The rate of complication is lowering with the increase in center expertise. AIMS: The aim of this study was to examine the onset of pressure sores and other complications caused by the use of prone position in patients having ARDS. DESIGN: This is a single-center, retrospective, observational study. RESULTS: One hundred seventy patients were enrolled, with a median age of 49 years (interquartile range [IQR], 38-63). Of all participants, 58% (n = 98) survived the intensive care unit recovery. The total prone position maneuvers were 526, with a median of 2 prone position sessions for each patient (IQR, 1-3). The median length of the prone position session was 9 hours (IQR, 7-12). Twenty-three patients developed pressure sores after prone position (14%). The anatomical positions of pressure sores were as follows: face/chin, 5% (n = 8); face/cheekbones, 6% (n = 11); thorax, 2% (n = 3); trochanter, 1% (n = 1); and other sites, 5% (n = 8). Complications were observed in 1% (n = 6) of all pronation maneuvers (vomit, 2%; respiratory device removal, 0.4%). No removal of intravascular catheter was observed. CONCLUSIONS: The onset rate of complications given by the use of prone position in ARDS patients is similar to data reported by previous literature. The implementation of a dedicated protocol in specialized centers and the involvement of 5 trained and skilled professionals while moving the patient in the prone position are recommended to prevent the occurrence of similar adverse events.

Acute Respiratory Distress Syndrome Definition, Causes, and Pathophysiology.

First successfully described in 1967, acute respiratory distress syndrome has since garnered much interest and debate. Extensive studies and clinical trials have been carried out in efforts to address the associated high mortality; however, it remains a significant burden on health care. Despite the heterogeneous etiologies that lead to the development of acute respiratory distress syndrome, this rapidly progressing form of respiratory failure, characterized by severe hypoxemia and nonhydrostatic pulmonary edema, has a recognizable pattern of lung injury. In this chapter, we will review the clinical manifestations, definitions, causes, and a brief overview of the pathophysiology of this complex syndrome.

Score for Predicting Ventilator Weaning Duration in Patients With Tracheostomies.

BACKGROUND: Factors affecting the timing of ventilator liberation among patients requiring prolonged mechanical ventilation (≥21 consecutive days) are poorly understood. After tracheostomy placement, ventilator liberation typically involves daily reductions in ventilator support as patients regain the capacity to breathe independently. OBJECTIVES: To determine the association between ventilator requirements on the day after tracheostomy placement and subsequent weaning duration. METHODS: Retrospective review of medical records of adults with tracheostomies treated at an academic medical center from 2011 to 2015. A new ventilator independence score based on ventilator settings on the day after tracheostomy was developed. Scores range from 0% to 100%; higher scores reflect greater levels of unassisted breathing for a greater proportion of the day. A multi-variable competing-risk survival regression model was used to determine the association between the ventilator independence score and time from tracheostomy placement to ventilator liberation. RESULTS: Of 372 patients, 72% were liberated from mechanical ventilation. The ventilator independence score measured on the day after tracheostomy placement had an area under the receiver operating characteristic curve value of 0.71 (95% CI, 0.65-0.76) for differentiating patients who were liberated within the next 14 days from those who were not. Median time from tracheostomy placement to ventilator liberation was 41 days for patients with a score of 0%, 20 days for scores between 0% and 50%, 15 days for scores between 50% and 75%, and 10 days for scores between 75% and 100%. CONCLUSIONS: A score derived from ventilator settings may help clinicians predict the timing of ventilator liberation in patients requiring prolonged mechanical ventilation.

Application of prone position in hypoxaemic patients supported by veno-venous ECMO.

INTRODUCTION: Veno-Venous Extracorporeal Membrane Oxygenation (VV-ECMO) is an advanced respiratory care therapy allowing replacement of pulmonary gas exchange. Despite VV-ECMO support, some patients may remain hypoxaemic. A possible therapeutic procedure for these patients is the application of prone positioning. OBJECTIVE: The primary aim of the present study was to investigate modification of the PaO2/FiO2 ratio, in VV-ECMO patients with refractory hypoxaemia. The secondary aim was to evaluate the safety and feasibility of prone positioning for patients with severe Adult Respiratory Distress Syndrome supported by ECMO. METHODS: We retrospectively reviewed the electronic records and charts of all patients supported by VV-ECMO who experienced at least one pronation. Complications related with prone positioning were also recorded. First PaO2/FiO2 ratio was analysed during four different time steps: before pronation, one hour after pronation, at the end of pronation and one hour after returning to supine. RESULTS: A total of 45 prone positioning manoeuvers were performed in 14 VV-ECMO patients from November 2009 to November 2014. The median duration of prone positioning cycles was 8 hours (IQR 6-10). No accidental dislodgement of intravascular lines, endotracheal tubes, chest tubes or a decrease in ECMO blood flow was observed. During the first prone positioning for each patient, the median PaO2/FiO2 ratio recorded was 123 (IQR 82-135), 152 (93-185), 149 (90-186) and 113 (74-182), during PRE-supine step, 1 h-prone positioning step, END-prone positioning step, and POST-supine step respectively. CONCLUSIONS: The application of prone positioning during VV-ECMO has shown to be a safe and reliable technique when performed in a recognised ECMO centre with the appropriately trained staff and standard procedures.

[Prone Position and Nursing Care].

Acute respiratory distress syndrome (ARDS) is a life-threatening disease, as acute inflammation in the lungs typically leads to hypoxia and symptoms of dyspnea. The treatment modalities of ARDS include mechanical ventilation, corticosteroid, extracorporeal membranous oxygenation, inhaled nitrogen oxide, and the prone position. Among these, the prone position is supported by evidence showing significantly reduced mortality in patients that adopt this modality. Lying in the prone position reduces atelectatic lung volumes by recruitment of dependent parts and facilitates normal regulation of alveolar ventilation, giving better-matched ventilation perfusion and, thus, improved oxygenation. Lying in the prone position should be initiated as early as possible and may be implemented when there is limited improvement after 12-24 hours under mechanical ventilation and when the PaO2/FiO2 ratio is less than 150 mmHg. However, the prone position may not be appropriate for patients with increased intracranial pressure, hemodynamic instability, an open abdominal wound, or pregnancy. Prior to setting a patient in the prone position, fixation of tubings should be affirmed, and all tubings should be reexamined after each adjustment in position in order to ensure that they are free of twists and function well. In addition, caution should be given to the skin at pressure points to avoid pressure sores and foam dressings may be applied in advance for protection. This article summarizes the pathophysiology of ARDS, the principle of applying the prone position, and related indications, complications, and nursing care in order to give nurses more confidence in caring for patients using the prone position.

School Nurses on the Front Lines of Medicine: Take a BREATH: The Approach to a Student With Respiratory Distress.

Students presenting with varying degrees of respiratory symptoms and distress occur commonly in the school setting. It is important to develop a differential diagnosis for respiratory distress, to initiate stabilization of the student with life-threatening symptoms, and to triage these students to an appropriate level of care (back to the classroom, home with their guardian with follow up at their primary health care provider's office, or directly to the closest emergency department via Emergency Medical Services). This article describes the initial assessment and management of a student presenting with respiratory distress.

[Enteral nutrition during prone positioning in mechanically ventilated patients]. / Nutrizione enterale continua durante la postura prona in pazienti in ventilazione invasiva.

. Enteral nutrition during prone positioning in mechanically ventilated patients. INTRODUCTION: The Enteral Nutrition (EN) tends to be stopped during prone positioning to prevent the risk of acid reflux and vomiting. AIMS: To compare the gastric residual volume during continuous enteral nutrition in patients in prone and supine position. METHODS: Observational restrospective study on Acute Respiratory Distress Syndrome patients, mechanically ventilated, with continuous enteral nutrition implemented according to the same protocol, in prone and supine position. RESULTS: The 25 patients included had a mean age of 51.13±15.93 (range: 16-80) years. Gastic residual volume was checked on 656 occasions (408 in supine and 248 in prone position). Mean infusion rate was 63.3±18.5 ml/h: 62.1±18.9 ml/h in supine and 66.2±16.5 ml/h in prone position. The mean overall gastric residual volume was 24.4±54.2 ml: 20.6±18.9 ml in supime and 23.6±50.0 ml in prone posizion. In 4 occasions (2 in prone and 2 in supine position9, the gastric residual volume was > 300ml; EN was interrupted on 1 occasion with a gastric residual volume >500ml. CONCLUSIONS: No clinically relevant differences of gastric residual volume were observed in prone and supine position. A protocol for the management of gastric residual volume allows a safe and effective administration of EN also in patients positioned for several hours in prone position.

Optimizing Oxygenation in the Mechanically Ventilated Patient: Nursing Practice Implications.

Critical care nurses constitute front-line care provision for patients in the intensive care unit (ICU). Hypoxemic respiratory compromise/failure is a primary reason that patients require ICU admission and mechanical ventilation. Critical care nurses must possess advanced knowledge, skill, and judgment when caring for these patients to ensure that interventions aimed at optimizing oxygenation are both effective and safe. This article discusses fundamental aspects of respiratory physiology and clinical indices used to describe oxygenation status. Key nursing interventions including patient assessment, positioning, pharmacology, and managing hemodynamic parameters are discussed, emphasizing their effects toward mitigating ventilation-perfusion mismatch and optimizing oxygenation.

PEEP titration during prone positioning for acute respiratory distress syndrome.

No major trial evaluating prone positioning for acute respiratory distress syndrome (ARDS) has incorporated a high-positive end-expiratory pressure (high-PEEP) strategy despite complementary physiological rationales. We evaluated generalizability of three recent proning trials to patients receiving a high-PEEP strategy. All trials employed a relatively low-PEEP strategy. After protocol ventilator settings were initiated and the patient was positioned per treatment assignment, post-intervention PEEP was not more than 5 cm H2O in 16.7 % and not more than 10 cm H2O in 66.0 % of patients. Post-intervention PEEP would have been nearly twice the set PEEP had a high-PEEP strategy been employed. Use of either proning or high-PEEP likely improves survival in moderate-severe ARDS; the role for both concomitantly remains unknown.

Prone Positioning of Patients With Acute Respiratory Distress Syndrome.

Effectively treating critically ill patients with acute respiratory distress syndrome (ARDS) is a challenge for many intensive care nurses. Multiple disease processes and injuries contribute to the complexity of ARDS and often complicate therapy. As a means of supportive care for ARDS, practitioners resort to rescue therapies to improve oxygenation and salvage the patient. The pathophysiology of ARDS and the use of prone positioning to improve pulmonary ventilation and oxygenation in ARDS patients are described. Educating nursing and medical staff on the use of prone positioning allows ease of patient placement with an emphasis on safety of both patients and staff. Scrupulous assessment of patients coupled with judicious timing of prone positioning expedites weaning from ventilatory support and contributes to positive outcomes for patients.
