Evaluating the use of PEEP in patients with acute respiratory failure

Official title: Application of PEEP in Patients With Acute Respiratory Failure Caused by Lung Injury: Assessment of Clinical Practice

Run by Hospital Universitario de Gran Canaria Doctor Negrín · NCT04912960 · Data updated 2026-11-12

This study is testing if using a breathing technique called PEEP can help improve oxygen levels and lung function in patients with severe breathing problems who are on a ventilator.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are intubated patients over 18 years old who require mechanical ventilation for more than 24 hours due to acute hypoxemic respiratory failure.

Probably not a fit

Patients with acute respiratory failure from non-pulmonary origins or those with contraindications to high PEEP will not benefit from this study.

What this trial studies

This observational study aims to assess the effectiveness of positive end-expiratory pressure (PEEP) in improving oxygenation and compliance in intubated patients with acute respiratory failure requiring mechanical ventilation. The study will evaluate whether the current practice of incrementally increasing PEEP levels leads to optimal outcomes, as previous findings from 1975 have not been validated in modern clinical settings. The research will involve monitoring patients who meet specific criteria, including those with acute hypoxemic respiratory failure. The goal is to determine if the historical application of PEEP remains relevant and beneficial in today's medical practice.

Why it matters

Potential benefit: If successful, this study could refine ventilation strategies for patients with acute respiratory failure, potentially improving their oxygenation and overall outcomes.

How similar studies have gone: While the foundational study from 1975 established the use of PEEP, this current assessment is novel as it seeks to validate those findings in the context of modern ventilation practices.
