U.S., July 8 -- ClinicalTrials.gov registry received information related to the study (NCT07688941) titled 'Preoperative Performance Indicators, Preoxygenation and Oxygen Reserve Relationship' on June 30.

Brief Summary: The goal of this observational study is to evaluate the relationship between preoperative cardiopulmonary performance indicators and preoxygenation efficiency along with oxygen reserve depletion in patients scheduled for elective surgery under general anesthesia. The main questions it aims to answer are:

What is the relationship between Hand Grip Strength (HGS) and the time taken for end-tidal oxygen (EtO\_2) to reach 90% during preoxygenation? What is the relationship between the 6-Minute Walk Test (6MWT) distance and the...
