Respiratory Strength Training in Cardiac Surgical Patients

Participants will complete RST exercises 5 days per week by performing 5 sets of 5 repetitions of both expiratory and inspiratory muscle strength training (a total of 50 repetitions per day). Trainer devices will be calibrated to 50% of participants' maximum expiratory pressure (MEP) and maximum inspiratory pressure (MIP) as determined via respiratory assessment prior to and during the RST program.
