HFNC During Bronchoscopy in COPD Patients
Sponsor: The First Affiliated Hospital of Guangzhou Medical University
Summary
Bronchoscopy diagnosis and treatment is highly irritating, and the effect of local topical anesthesia is poor; the airway is shared; and COPD patients have low oxygen reserves due to impaired lung function. At present, clinical anesthesia generally uses nasal cannula for oxygen inhalation. If the anesthesia is too shallow, it may cause airway spasm, and if the anesthesia is too deep, it will inhibit breathing and lead to hypoxia. Hypoxemia has been reported in 66% of COPD patients undergoing sedation for bronchoscopy. Therefore, solving hypoxia is the biggest problem in anesthesia for bronchoscopy diagnosis and treatment.

group N used traditional nasal cannula for oxygen inhalation
1000 COPD patients who underwent bronchoscopy were randomly divided into 2 groups in a 1:1 ratio.Nasal high-flow oxygen therapy group（group N） and nasal cannula oxygen inhalation group(group HFNC）.The N group used traditional nasal cannula for oxygen inhalation, and the HFNC group used nasal high-flow oxygen inhalation.
Group HFNC used nasal high-flow oxygen inhalation.
