Analysis of Advanced Physiological Ventilatory Parameters During Spontaneous Breathing Effort in Patients with Acute Hypoxemic Respiratory Failure
In Brief
An observational study for Acute Hypoxic Respiratory Failure. Completed, enrolled 31 participants across 1 site.
Detailed Summary
The aim of this prospective physiological cohort study conducted in a medical intensive care unit (ICU) at Hospital del Mar in Barcelona, Spain, was to analyze the proportion of time spent within the "safe" range of respiratory effort (including esophageal pressure swing (ΔPes), respiratory muscular pressure (Pmus), and transdiaphragmatic pressure swing (ΔPdi)) in patients with acute hypoxemic respiratory failure (AHRF) undergoing invasive mechanical ventilation (IMV), during the active breathing phase in relation to ICU survival. The investigators hypothesized that AHRF patients on IMV with better outcome (i.e., ICU survivors) spend more time within the "safe" range of respiratory effort during the active breathing phase compared to non-survivors. AHRF patients on IMV were continuously monitored with esophageal and gastric manometry from the detection of the onset of respiratory effort for up to 7 days, or until extubation, or until death, whichever occurred first.
