Physiological Effects of Continuous Negative External Pressure for Acute Hypoxemic Respiratory Failure

NCT05675345 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

No results posted yet for this study

Summary

This study is being conducted to evaluate if wearing a non-invasive breathing support device over the chest/abdomen improves markers of breathing in patients with lung injury requiring high-flow oxygen. The breathing support device consists of a plastic shell that sits over the chest and abdomen and connects to a vacuum that helps the chest expand with breathing. This breathing support is known as continuous negative external pressure (CNEP). Study findings will help determine if this breathing support device might be useful for patients with acute hypoxemic respiratory failure (AHRF).
