Abdominal Weight Training Assisted by Cough Assist Machine on Lung Function

Cough machine training is based on the cough assist machine Comfort Cough II (CC20), in which the inhalation and exhalation times are adjusted to 1-3 seconds, and the positive and negative pressure of the lower pressure 10-15 cmH2O is gradually increased to 30-40 cmH2O for the first time, 4-6 cycles/time, repeated 4-6 times, twice a day, five days a week, until the subject is weaned off the ventilator or transferred out of the ward. A modified Borg scale was used as an indicator of perceived dyspnea.

abdominal weight exercise training (sandbag) is maintained for 30 minutes; the starting weight is 1kg to 2kg, and the previous day's weight is maintained each day as well as adding 0.5kg daily.
