Objectives One-lung ventilation is considered to be mandatory in video-assisted thoracoscopic surgery. However, the authors showed in a previous report that two-lung ventilation with low tidal volume is feasible in thoracoscopic bleb resection (TBR). In this study, they evaluated optimal respiratory rate during TBR under two-lung ventilation with low-tidal volume anesthesia. Design A prospective, randomized, single-blinded intervention study. Setting An operating room in a teaching hospital. Participants Forty-eight patients who underwent scheduled TBR under general anesthesia. Interventions TBR was performed under low-tidal-volume (5 mL/kg), two-lung ventilation. Respiratory rate (RR) varied according to the protocol: 15 (group I), 18 (group II), and 22 cycles/min (group III). Using block randomization method, 16 patients were assigned to each of 3 groups. Measurements and Main Results Minute ventilation of group I was lowered significantly compared with the other groups (p
