Analysis of Breath Sounds During Surgery

Recruiting now

Conditions studied: General Anesthesia, Intraoperative Monitoring, Respiratory Sounds

In brief

This study aims to analyze breath sounds during surgery by using electronic stethoscope sensors attached to patients under general anesthesia. The study will evaluate whether breath sound monitoring can provide useful information for respiratory management, assist anesthesiologists in early detection of abnormal breathing events, and support safer perioperative care. A total of 30 adult patients undergoing elective surgery under general anesthesia will be enrolled.
