Prone positioning improves clinical outcomes in moderate-to-severe acute respiratory distress syndrome and has been widely adopted for the treatment of patients with acute respiratory distress syndrome due to coronavirus disease 2019. Little is known about the effects of prone positioning among patients with less severe acute respiratory distress syndrome, obesity, or those treated with pulmonary vasodilators. ⋯ Prone positioning improves oxygenation across the acute respiratory distress syndrome severity spectrum, irrespective of supine respiratory system compliance, positive end-expiratory pressure, or body mass index. There was a greater relative benefit among patients with more severe disease. Prone positioning confers an additive benefit in oxygenation among patients treated with inhaled nitric oxide.

To evaluate whether different approaches in note text preparation (known as preprocessing) can impact machine learning model performance in the case of mortality prediction ICU.

Carotid Doppler ultrasound is used as a measure of fluid responsiveness, however, assessing change with statistical confidence requires an adequate beat sample size. The coefficient of variation helps quantify the number of cardiac cycles needed to adequately detect change during functional hemodynamic monitoring.

Extracorporeal membrane oxygenation is used as rescue therapy for patients with acute respiratory distress syndrome in whom conventional therapy has failed prior to an Extra Corporeal Membrane Oxygenator to rescue Lung Injury in Severe Acute Respiratory Distress Syndrome trial. Since then, extracorporeal membrane oxygenation has been incorporated as part of the standard treatment algorithm in many centers for patients with severe acute respiratory distress syndrome. Since the emergence of coronavirus disease 2019 in early 2020, extracorporeal membrane oxygenation has been used effectively as rescue therapy and as a bridge to recovery in some patients with refractory respiratory failure. ⋯ To our knowledge, this is one of the first cases to be reported in the literature on the use of awake extracorporeal membrane oxygenation as a "treatment" for barotrauma due to severe acute respiratory distress syndrome in a coronavirus disease 2019 patient, without the need for invasive mechanical ventilation. In selected patients with severe respiratory failure, awake extracorporeal membrane oxygenation can be used as a salvage treatment and obviate the need for invasive mechanical ventilation.
