Core Warming of Coronavirus Disease 2019 Patients Undergoing Mechanical Ventilation: A Pilot Study.

Fever is a recognized protective factor in patients with sepsis, and growing data suggest beneficial effects on outcomes in sepsis with elevated temperature, with a recent pilot randomized controlled trial (RCT) showing lower mortality by warming afebrile sepsis patients in the intensive care unit (ICU). The objective of this prospective single-site RCT was to determine if core warming improves respiratory physiology of mechanically ventilated patients with coronavirus disease 2019 (COVID-19), allowing earlier weaning from ventilation, and greater overall survival. A total of 19 patients with mean age of 60.

Emergency bedside extracorporeal membrane oxygenation for rescue of acute tracheal obstruction.

A 39-year-old man experienced total obstruction of a distal tracheal plastic stent by a tumor mass, preventing effective ventilation and resulting in cardiac arrest. Resuscitation by emergency bedside venoarterial extracorporeal membrane oxygenation (ECMO) permitted time to physically remove the obstructing tumor and reestablish successful ventilation and liberation from ventilatory support. We review several other reported cases of emergency ECMO to resuscitate patients with acute airway obstruction.

Survey of respiratory therapists' attitudes and concerns regarding terminal extubation.

Background: There is little published information on the role of respiratory therapists in the process of withdrawal of mechanical ventilatory support.

Methods: We surveyed practicing respiratory therapists at 6 acute-care hospitals in a large urban area and asked about particular concerns and attitudes regarding terminal extubation.

Results: One hundred nineteen questionnaires were analyzed.

A laboratory evaluation of 2 mechanical ventilators in the presence of helium-oxygen mixtures.

Background: Helium-oxygen (heliox) mixtures are being used more frequently with mechanical ventilators. Newer ventilators continue to be developed that have not yet been evaluated for safety and efficacy of heliox delivery. We studied the performance of 2 previously untested ventilators (Servo-i and Inspiration) during heliox administration.
