Cardiac rehabilitation is defined by the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) as the delivery of all-inclusive, long-term services that include medical evaluation, prescription exercise, modification of cardiac risk factors, education, counseling, and behavioral interventions. The inspiratory muscle trainer device benefits includes improved pulmonary function, respiratory muscle strength and endurance, functional capacity, physical activity, and health-related quality of life used  patients.Efficacy of inspiratory muscle trainer during Phase 1 of cardiac rehabilitation has not been well studied.

This randomized clinical trial aimed to evaluate and  the effects of Inspiratory muscle trainer  who underwent  Phase 1 of their cardiac rehabilitation. 

Procedure : Participants will be selected and screened based on inclusion and exclusion criteria. Details about the study and intervention will be explained to the participants and an informed written consent form will be obtained. Patient’s will be Randomly divided through block randomisation method into Group A (control  ) and Group B ( IMT). Outcomes will be assessed on pod 1 and treatment will be given from POD 2 to POD 6 to Patients who underwent through cardiac rehabilitation  On Postoperative day 6 outcomes will be reassessed. Data will be collected from both groups and analyzed for significant differences in pulmonary function and airway clearance improvements. Statistical tests will be used to compare the efficacy of inspiratory muscle trainer  devices in enhancing respiratory outcomes in phase 1 cardiac rehab patients.
