Number of participants that the trial has enrolled

35

Results

R5, R20, Z5 and the resonance coefficient increased as the pregnancy progressed, but the changes were strong after 30 weeks, and the changes in R5, R20 and Z5 correlated with the amount of weight gain. It was suggested that the change in lung function associated with pregnancy was strong after 30 weeks, and that the degree of change was affected by weight gain.

Baseline Characteristics

The subjects were 35 cases scheduled for cesarean section at Showa University Hospital and Showa University Fujigaoka Hospital. The measurement period was from 17 to 37 weeks of gestation, and IOS was measured every 4 weeks.

Outcome measures

R5-R20 was calculated by measuring the respiratory resistance R5 and R20, impedance (Z5), reactance (X5), resonance coefficient, etc. when 5Hz and 20Hz impulses were applied using IOS in the sitting position.
