BTV
SECONDARY, PNEUMOPERITONEUM
The respiratory circuit was disconnected at T0, T1, and T2 time points as described by Seo H and Kim SH et al. [Method for measuring bronchial mucus transport velocity (BTV). Data were collected at the following time points:Baseline; 5 min after endotracheal intubation and before initiation of the pneumoperitoneum (T0)Post pneumoperitoneum (1 h after complete COPost pneumoperitoneum (2 h after complete COBTV at T0, T1 and T2 was the primary outcome. The secondary outcomes included heart rate (HR), mean arterial pressure (MAP), body temperature, PETCO2, VT, PIP, mean inspiratory pressure (P mean), respiratory rate (RR), and dynamic compliance (CDyn) at T0, T1, and T2.
