  1. Measurement data are expressed as means ± SD. Counting data were expressed as numbers and percentages. *was statistically significant compared with Group H, P < 0.05. Compared with group H, right and left lung residual volume were significantly (bold) increased in the group L (P = 0.04, P = 0.01)
  2. Group H, high negative suction pressure group; Group L, low negative suction pressure group
  3. PIP peak inspiratory pressure
