Long-term survival comparison between the first and second waves among 265 critical COVID-19 patients admitted to the ICU: A retrospective cohort study.

Backgroud: Management of severe COVID-19 patients admitted to ICU considerably evolved during the first months of the pandemic. It is unclear, however, whether these changes improved long-term survival of these critically ill patients.

Methods: We conducted a retrospective cohort study in adults with COVID-19 pneumonia admitted to a French ICU between February 2020 and January 2021, a timeframe that covered the first two waves of the pandemic.

Does using pressure-controlled ventilation to rest respiratory muscles improve sleep in ICU patients?

Purpose: Sleep is commonly altered in critically ill patients. Ventilatory mode may impact on quality of sleep. The aim of our study was to evaluate the effect on sleep of pressure-controlled ventilation (PCV) to spontaneous ventilation with 6 cm H2O inspiratory pressure (low-PSV).

Assist-control ventilation vs. low levels of pressure support ventilation on sleep quality in intubated ICU patients.

Objective: To compare the impact of assist-control ventilation (ACV) and pressure support ventilation with 6 cmH2O inspiratory pressure (low PSV) on sleep quality.

Design: Prospective randomized cross-over study.

Patients: Twenty intubated and mechanically ventilated patients for acute on chronic respiratory failure.
