New ventilator strategy aims to help ICU patients breathe easier
NCT ID NCT06526598
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new method for setting ventilator support in ICU patients with acute hypoxic respiratory failure. Instead of using traditional targets like breath size and rate, the new approach adjusts support based on how hard the patient is breathing. The goal is to see if this leads to more days off the ventilator and better recovery. About 619 adults will take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Mechanically ventilated patients, who are admitted to the ICU with acute hypoxic respiratory failure, will be consecutively screened daily at 08:00-10:00 morning rounds. Inclusion criteria: 1. PSV initiated during the last 24 hours; 2. Mechanical ventilation expected to be required for at least 24-48 h by responsible physicians; 3. The partial pressure of oxygen in arterial blood (PaO2)/inspired oxygen fraction (FiO2) ≤ 300 mmHg (measuring at clinical FiO2 and positive end-expiratory pressure PEEP); 4. No sedation or stable sedation with Richmond Agitation Sedation Scale (RASS) of -2 to +1 or Riker's Sedation-Agitation Scale (SAS) of 3 to 4. Exclusion criteria included: 1. Age younger than 18 years old; 2. Initiation of PSV before ICU admission; 3. Duration of mechanical ventilation longer than 7 days before enrollment; 4. History of neuromuscular diseases; 5. Clinical suspicion of increased intracranial pressure; 6. Extracorporeal support; 7. Moribund conditions; 8. Refusal by the ICU physicians or the patient.
