Clinical Trial: "Comparison of Oxygen Reserve Index (ORI), End-Tidal Oxygen, and Time-Based Preoxygenation Targets With Arterial Blood Gas During Preoxygenation

U.S., Nov. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07921849) titled '"Comparison of Oxygen Reserve Index (ORI), End-Tidal Oxygen, and Time-Based Preoxygenation Targets With Arterial Blood Gas During Preoxygenation' on Nov. 02.

Brief Summary: The goal of this observational study is to learn how well different preoxygenation targets reflect the actual amount of oxygen in the blood in adults having planned surgery under general anesthesia. Preoxygenation means breathing pure oxygen through a face mask before going to sleep, so that the body has an oxygen reserve while the breathing tube is placed.

Doctors usually decide that preoxygenation is adequate either after 3 minutes of breathing oxygen or when t...
