NCT ID NCT04131660

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study compared two types of non-invasive breathing support for people with sudden breathing failure who are obese or have sleep apnea. One machine automatically adjusts pressure and volume, while the other uses a fixed pressure setting. The goal was to see which method clears carbon dioxide from the blood faster and reduces breathing pauses during sleep. Only 14 people participated before the study was stopped early.
