tidal respiration

Various parameters of pulmonary function were measured at 1st hour, 12 to 24 hour, 3 to 5 days after birth by using method of tidal respiration.

采用潮气呼吸法测定两组新生儿出生后第1小时内、第1224小时内（第1天）、第3天、第5天的潮气呼吸肺功能的各项指标。

All guinea pigs were general anesthetized, trachea incised, and muscles relaxed. Artificial respiration was used, the respiratory rate was set at 70 breaths/ min, with 1.5ml/breath of tidal volume.

全部豚鼠在实验过程中采用全身麻醉，气管切开插管，使用肌肉松弛剂并实施人工呼吸，呼吸频率70次／分，潮气量1.5ml／次，同时监测全身平均血压，保持直肠温38℃。

Cheyne-Stokes respiration with central sleep apnea is a form of periodic breathing in which apneas and hypopneas alternate with ventilatory periods having a waxing-waning pattern of tidal volume.

伴有中枢性睡眠呼吸暂停的Cheyne-Stokes呼吸是一种周期性的呼吸节律异常，其特征是交替性发生低通气、呼吸暂停与过度通气，在过度通气阶段，呼吸运动呈逐渐增强&逐渐减弱的形式。
