PURPOSE: Emergency department (ED) patients are at high risk for the acute respiratory distress syndrome (ARDS). Settings only 1 mL/kg above recommended tidal volumes confers harm for these patients. The purpose of this study was to determine whether ED physicians routinely initiate mechanical ventilation with low tidal volumes in patients at risk for ARDS. MATERIALS AND METHODS: We retrospectively reviewed the charts of all adult patients who were intubated in an urban, academic ED...

BACKGROUND: The sickest patients often require mechanical ventilation. Although mechanical ventilation is often a lifesaving intervention for many, it can also have life-threatening complications. Monitoring a patient on mechanical ventilation requires skill and prompt troubleshooting to ensure its proper function. The high peak airway pressure (HPAP) alarm is one of the most common alarms. It is critically important that clinicians understand the pathophysiology of the lung and the various causes behind the alarm and have a working differential diagnosis for the causes of HPAPs...

INTRODUCTION: Emergency physicians frequently perform endotracheal intubation and mechanical ventilation. The impact of instituting early post-intubation interventions on patients boarding in the emergency department (ED) is not well studied. We sought to determine the impact of post-intubation interventions (arterial blood gas sampling, obtaining a chest x-ray (CXR), gastric decompression, early sedation, appropriate initial tidal volume, and quantitative capnography) on outcomes of mortality, ventilator-associated pneumonia (VAP), ventilator days, and intensive care unit (ICU) length-of-stay (LOS)...

BACKGROUND: The goal of mechanical ventilation in acute hypoxemic respiratory failure is to support adequate gas exchange without harming the lungs. How patients are mechanically ventilated can significantly impact their ultimate outcomes. METHODS: This review focuses on emerging evidence regarding strategies for mechanical ventilation in patients with acute hypoxemic respiratory failure including: low tidal volume ventilation in the acute respiratory distress syndrome (ARDS), novel ventilator modes as alternatives to low tidal volume ventilation, adjunctive strategies that may enhance recovery in ARDS, the use of lung-protective strategies in patients without ARDS, rescue therapies in refractory hypoxemia, and an evidence-based approach to weaning from mechanical ventilation...

The lung-protective mechanical ventilation strategy has been standard practice for management of acute respiratory distress syndrome (ARDS) for more than a decade. Observational data, small randomized studies and two recent systematic reviews suggest that lung protective ventilation is both safe and potentially beneficial in patients who do not have ARDS at the onset of mechanical ventilation. Principles of lung-protective ventilation include: a) prevention of volutrauma (tidal volume 4 to 8 ml/kg predicted body weight with plateau pressure<30 cmH2O); b) prevention of atelectasis (positive end-expiratory pressure‚Č•5 cmH2O, as needed recruitment maneuvers); c) adequate ventilation (respiratory rate 20 to 35 breaths per minute); and d) prevention of hyperoxia (titrate inspired oxygen concentration to peripheral oxygen saturation (SpO2) levels of 88 to 95%)...

BACKGROUND: Traditional approaches to mechanical ventilation use tidal volumes of 10 to 15 ml per kilogram of body weight and may cause stretch-induced lung injury in patients with acute lung injury and the acute respiratory distress syndrome. We therefore conducted a trial to determine whether ventilation with lower tidal volumes would improve the clinical outcomes in these patients. METHODS: Patients with acute lung injury and the acute respiratory distress syndrome were enrolled in a multicenter, randomized trial...
