Assessment of PaO2/FiO2 Ratio Pre and POst INTubation (NCT05853068)

Assessment of PaO2/FiO2 Ratio Pre and POst INTubation (The APPOINT Study)

🔵 Active, Not Recruiting Interventional Protocol 📊 Observational Clinical Research Sponsor: Hospital Universitario de Gran Canaria Doctor Negrín

🩺 Plain-English Summary (8th-Grade Level)

We designed this study to dtermine whether invasive mechanical ventilation (MV) would have an impact on the reclassification of patients with acute hypoxemic respiratory failure (AHRF) -treated previously with non-invasive respiratory support- into categories of severity (mild, moderate, and severe). Our hypothesis is that the assessment of PaO2/FiO2 ratio on PEEP greater or equal to 5 cmH2O after intubation, in patients labeled as mild/moderate/severe AHRF while on non-invasive respiratory support, would identify that a marked proportion of patients would change the degree of severity after a brief period of invasive MV
