Effects of Respiratory Muscle Training in Mechanically Ventilated Adults

Respiratory muscle training is done twice every day, with 3 series of 10 repetitions each, with a resting pause of two minutes between series (during resting time, patient is connected to mechanical ventilation again). We adjust initial load for respiratory muscle training as 50% of MIP. At the end of every training session, we assess dyspnea (perceived effort) using Modified Borg Scale (23). Four physical therapists are in charge of Respiratory muscle training, these therapists work at ICU and have experience with critically ill patients.

Control group receives Cardiopulmonary Physical Therapy every 6 hours, physical therapy and mechanical ventilation management
