Preoxygenation strategies for endotracheal intubation in resource-limited settings: reframing the basics

Summary This editorial reviews evidence-based strategies for preoxygenation during endotracheal intubation (ETI) specifically tailored to resource-limited settings (LRS). The authors underscore the challenges faced in achieving optimal preoxygenation where advanced devices are unavailable. They propose practical, low-cost alternatives and highlight recent evidence supporting the effectiveness of methods such as high-flow nasal cannula (HFNC), non-invasive positive

Revisiting Acute Respiratory Distress Syndrome ventilation management: Time for a paradigm shift focusing on tidal volume

Abstract: Merola and colleagues critically evaluate current Acute Respiratory Distress Syndrome (ARDS) ventilation strategies, emphasizing limitations inherent in universally applying low tidal volume (VT) strategies. They argue for personalized, physiology-driven ventilation approaches that incorporate mechanical power, compliance, and transpulmonary pressures. The authors highlight the complexity and heterogeneity of ARDS, suggesting the inadequacy of global parameters

Neurally adjusted ventilatory assist in critical care patients with and without obesity: a prospective randomized crossover study

🫁 NAVA vs PSV in Obese ICU Patients: First Evidence of Safety and Benefit   Abstract: This randomized crossover study is the first to test Neurally Adjusted Ventilatory Assist (NAVA) in critically ill obese patients. Twenty-one ventilated patients (10 obese, 11 non-obese) underwent 30 minutes of NAVA and PSV each. Researchers assessed safety, patient-ventilator synchrony,

Bridging the gap: Enhancing synchrony in mechanical ventilation

Summary This review extensively analyzes the physiological control mechanisms of ventilation and their interaction with mechanical ventilators, highlighting advanced technologies aimed at improving patient-ventilator synchrony. Ventilator dyssynchrony—defined as a mismatch between patient respiratory effort and ventilator support—remains prevalent, contributing significantly to adverse outcomes, including prolonged ventilation, diaphragm dysfunction, extended ICU stays, and increased mortality. The
