High frequency jet ventilation through mask contributes to oxygen therapy among patients undergoing bronchoscopic intervention under deep sedation

Table 4 Multiple linear regression analysis of blood gas PaO₂ related factors

Variables	Regression coefficient	95% Confidence interval	P Value
Body mass index	−4.6	(−9.0, −0.2)	0.040
Procedure duration	2.1	(0.8, 3.5)	0.002
Group COT/NFJV/HFJV	6.5	(−10.3, 23.3)	0.447

Multiple linear regression results showed that body mass index and procedure duration were independent influencing factors of blood gas PaO₂ respectively
COT conventional oxygen therapy; NFJV normal frequency jet ventilation; HFJV high frequency jet ventilation
