These cardiopulmonary disorders like COPD, heart failure and post-cardiac surgery often influence functional capability, physical stamen and lifestyle. These chronic diseases are frequent causes of disability and mortality around the globe and, therefore, require inclusive and efficient approaches to rehabilitation. Cardio-pulmonary rehabilitation involves using physical PT exercise routines, breathing techniques and lifestyle modification to enhance the clients' physical fitness and ultimately enhance the clinical results. PT evidence-based writings centred on the improvement of aerobic fitness, respiratory muscles, symptoms decrease, and increased functional mobility. These include diaphragmatic breathing, inspiratory muscle training (IMT), as well as progressive respiratory muscle strength training with due consideration to the strengths and realities of every patient. Using HIIT, telerehabilitation and VR-based therapies is changing the conventional methods of PT and is making rehabilitation more interactive, feasible and efficient. These methods use contemporary technology to enhance medicines compliance, counselling and feedback, and quality greatly in extent fewer served. Besides exercise interventions, other approaches in different professional disciplines, such as dietetics, counselling, and informative support for the patient, all augment results. These general intervention models include: These approaches consider much more than simply the physiological disabilities of cardio-pulmonary diseases, but also the psychological and social aspects involved. Papers show that PT is an important factor that helps prevent readmissions, mortalities and better long-term outcomes.
