The 90% Effective Flow of High Flow Nasal Oxygenation (HFNO) During Sedated Bronchoscopy — HFNO  

Hypoxia Clinical Trial

Official title:
The 90% Effective Flow of High Flow Nasal Oxygenation During Deeply Sedated Bronchoscopy

Clinical Trial Summary

Patients undergoing sedated bronchoscopy were randomized into six groups (10 Liters/minute [L/min], 20 L/min, 30 L/min, 40 L/min, 50 L/min, 60 L/min). The primary outcome was the incidence of hypoxemia.

Clinical Trial Description

It's a double-blind, randomized trial. The patients'demographic information, such as sex, weight, height, smoking status, present illness and history of past illness, were collected. After successful peripheral intravenous access, all patients, before sedation, received 20 min nebulization with lidocaine via a nebuliser facemask. The basic oxygen saturation, heart rate, and blood pressure of the patients were recorded by the investigators.Patients in the HFNO group received humidified oxygen at different rates via a high-flow nasal cannula (AIRVO2, New Zealand). After sedation with propofol and sufentanil, continuous electrocardiography and pulse oximetry were recorded, and the blood pressure of the patients was monitored throughout the procedure. . After bronchoscopy, patients were transferred to the post anesthesia care unit (PACU) if their vital signs were stable. ;
