To investigate the differences in clinical course, ventilator mechanics, and outcomes of patients with coronavirus disease 2019 secondary to acute respiratory distress syndrome infection compared with a historical cohort of acute respiratory distress syndrome. ⋯ Patients with coronavirus disease 2019 secondary to acute respiratory distress syndrome infection demonstrated higher mortality compared with control patients hospitalized with acute respiratory distress syndrome prior to the pandemic, with progressive hypoxia throughout the study period, despite similar lung mechanics and initial Sequential Organ Failure Assessment score. Coronavirus disease 2019 infection, older age, paralytic use, and higher Sequential Organ Failure Assessment scores were independent risk factors for 28-day mortality across the entire cohort.

Non sedation - does it improve health-related quality of life after critical illness? A 3-month follow-up sub-study of the NONSEDA trial.
Critical illness is associated with severely impaired health-related quality of life (HRQoL) for years following discharge. The NONSEDA trial was a multicenter randomized trial on non-sedation versus sedation with a daily wake-up trial in critically ill, mechanically ventilated patients in Scandinavia. The aim of this sub-study was to assess the effect of non-sedation on HRQoL and degree of independence in activities in daily living (ADL) 3 months post-ICU. ⋯ Randomization to non-sedation neither improved nor impaired health-related quality of life or degree of independence in activities in daily living 3 months post-ICU discharge.

Observational StudyPeripheral perfusion index as a predictor of failed weaning from mechanical ventilation.
We hypothesized that impairment of peripheral perfusion index (PPI) during spontaneous breathing trial (SBT) might be predictive of weaning failure. We included 44 consecutive, adult, patients, who were scheduled for weaning after at least 48 h of invasive mechanical ventilation in this prospective observational study. Weaning failure was defined as failed SBT or reintubation within 48 h of extubation. ⋯ Patients with successful weaning showed higher augmentation of PPI during the SBT compared to re-intubated patients. Failure of augmenting the PPI by 41% at the end of SBT could predict re-intubation with negative predictive value of 95%. Clinical trial identifier: NCT03974568. https://clinicaltrials.gov/ct2/show/NCT03974568?term=ahmed+hasanin&draw=3&rank=17.

We hypothesized that the lack of benefit of setting a low versus a high PEEP in patients with ARDS may be due in part to differences in the dynamic behavior of the expiratory valve in ventilators. We tested this hypothesis by conducting a bench comparison of the dynamic behavior of expiratory valves on ICU ventilators currently in use. ⋯ The resistance of active expiratory valves differed significantly between the 7 ICU ventilators tested.
