Heart Rate Variability as a Marker to Guide High-Flow Nasal Cannula Therapy
We’re testing whether heart rate variability can help decide the right flow rate for high-flow nasal cannula in adults with respiratory failure.
-
High-flow nasal oxygen versus face mask oxygen for sedated gastroscopy in people with visceral obesity
This test sees if using high-flow nasal oxygen instead of a standard face mask keeps oxygen levels better during sedated gastroscopy for people with visceral obesity.
-
Using high-flow nasal oxygen for preoxygenation in emergency surgery patients with full stomachs
This study is testing if high-flow nasal oxygen can help emergency surgery patients with full stomachs breathe better before anesthesia compared to using a regular face mask.
-
Using high-flow nasal cannula to prevent low oxygen levels during intubation in children
This study is testing if using a high-flow nasal cannula can help prevent low oxygen levels in children aged 2-10 during the process of intubation for surgery.
-
Preventing lung complications after gynecologic surgery using high-flow nasal oxygen
This study is testing if high-flow nasal oxygen can help prevent lung problems after gynecologic surgery in patients who are at high risk for these issues.
