Patent foramen ovale (PFO) is an anatomic variant that may lead to several pathological conditions, notably right to left shunt, paradoxical embolism, hypoxemia, and cerebral fat embolism. Mechanical positive pressure ventilation may increase the prevalence of PFO opening in Intensive Care Unit (ICU) patients; however, the respiratory and hemodynamic determinants of PFO opening have been poorly investigated. Contrast-enhanced transesophageal echocardiogram (ce-TEE) is considered the gold standard for PFO detection. We prospectively performed a multicenter study using ce-TEE in order to determine the respiratory and hemodynamic factors that may lead to PFO opening. ⋯ In this group of mechanically ventilated, critically ill adult patients, right ventricular dilatation and plateau pressure above 26 mmHg were significantly associated with foramen ovale opening.

Multicenter Study Pragmatic Clinical Trial
Early intervention of patients at risk for acute respiratory failure and prolonged mechanical ventilation with a checklist aimed at the prevention of organ failure: protocol for a pragmatic stepped-wedged cluster trial of PROOFCheck.
Acute respiratory failure (ARF) often presents and progresses outside of the intensive care unit. However, recognition and treatment of acute critical illness is often delayed with inconsistent adherence to evidence-based care known to decrease the duration of mechanical ventilation (MV) and complications of critical illness. The goal of this trial is to determine whether the implementation of an electronic medical record-based early alert for progressive respiratory failure coupled with a checklist to promote early compliance to best practice in respiratory failure can improve the outcomes of patients at risk for prolonged respiratory failure and death. ⋯ The study was approved by the institutional review boards. Results will be published in peer-reviewed journals and presented at international meetings.

The use of neuromuscular blocking agents (NMBAs) early in the development of ARDS has been a strategy of interest for many years. The use of NMBAs with a concomitant deep sedation strategy can increase oxygenation and possibly decrease mortality when used in the early stages of ARDS. ⋯ The use of NMBA and deep sedation for these patients is not without consequence. This discussion describes the rationale and evidence behind the use of NMBAs in the setting of ARDS.

Sleep after critical illness: Study of survivors of acute respiratory distress syndrome and systematic review of literature.
This study aims to evaluate the sleep quality, architecture, sleep-related quality of life, and sleep-disordered breathing (SDB) in acute respiratory distress syndrome (ARDS) survivors early after discharge. ⋯ Sleep disturbances are common in ARDS survivors early after discharge from the ICU.

For the past 4 decades, the prone position has been employed as an occasional rescue option for patients with severe hypoxemia unresponsive to conventional measures applied in the supine orientation. Proning offers a high likelihood of significantly improved arterial oxygenation to well selected patients, but until the results of a convincing randomized trial were published, its potential to reduce mortality risk remained in serious doubt. Proning does not benefit patients of all disease severities and stages but may be life-saving for others. Because it requires advanced nursing skills and escalation of monitoring surveillance to deploy safely, its place as an early stage standard of care depends on the definition of that label.
