Fig. 3From: High frequency jet ventilation through mask contributes to oxygen therapy among patients undergoing bronchoscopic intervention under deep sedationAnesthetic doses among the three groups. No significant differences among three groups in propofol and remifentanil at different periods. Induction (Indu), maintenance (Main) and total (Total) dose of anesthetics during bronchoscopic intervention in the three groups were recorded.
