Knowledge and Practice of Mechanical Ventilation Humidification Systems in Latin American ICUs.

Humidification of inspired gases is critical for maintaining airway integrity in mechanically ventilated patients. However, airway instrumentation and the use of cold, dry medical gases can disrupt this process, necessitating external humidification systems. This study aimed to assess knowledge and practices regarding humidification systems in mechanical ventilation among health care professionals in Latin American ICUs.

High-Flow Nasal Cannula and Standard Oxygen in Acute Hypoxemic Respiratory Failure Due to COVID-19.

Background: The evidence regarding benefits of high-flow nasal cannula (HFNC) in patients with COVID-19 is controversial. The aim of this study was to evaluate the impact of HFNC in comparison with standard oxygen therapy on the frequency of endotracheal intubation at 28 d in subjects with acute hypoxemic respiratory failure (AHRF) secondary to SARS-CoV-2 infection.

Methods: A retrospective, age- and sex-matched-paired, cohort study was conducted in subjects with moderate-to-severe AHRF.
