Study Arms (2)

Flow-Controlled Ventilation Group

Patients undergoing elective suspension laryngoscopy who were ventilated using flow-controlled ventilation based on the attending anesthesiologist's clinical preference.

Volume-Controlled Ventilation Group

Patients undergoing elective suspension laryngoscopy who were ventilated using conventional volume-controlled ventilation based on the attending anesthesiologist's clinical preference.
