Comparing Manual and AutoFlow Ventilation Effects on Brain and Body Oxygen Levels During Anesthesia Induction in Patients 65 and Older

What this Trial Is About

Researchers are comparing manual ventilation and AutoFlow ventilation during the induction of general anesthesia to study their effects on brain and peripheral oxygen levels in older adults. This study focuses on patients aged 65 and older undergoing elective surgery, as age-related changes can affect breathing and blood flow, increasing the risk of low oxygen levels during anesthesia induction. The goal is to see if AutoFlow ventilation provides more stable oxygen delivery than manual ventilation in this population. Participants will receive general anesthesia with standard drugs followed by 2 minutes of mask ventilation using either manual ventilation by an anesthesiologist or AutoFlow ventilation delivered by a machine with preset settings including tidal volume, breathing rate, and pressure limits. Each patient is randomly assigned to one of these two groups to compare the effects on oxygen levels before and after intubation. During the study, researchers will continuously monitor oxygen saturation in the brain and peripheral tissues using special sensors, along with heart rate, blood pressure, and carbon dioxide levels at key times before, during, and after ventilation. This careful monitoring aims to measure how each ventilation method affects oxygen delivery and respiratory parameters. The study includes detailed data collection on patient characteristics and standard safety measurements throughout the procedure.
