Respiratory Physiotherapy and PMR After Cardiac Surgery

This study aims to evaluate the effects of respiratory physiotherapy combined with progressive muscle relaxation exercises on dyspnea, anxiety, hemodynamic status, and delirium symptoms in patients after cardiac surgery. This randomized controlled trial will include 116 patients who will be randomly assigned to an intervention group or a control group. The intervention group will receive respiratory physiotherapy and progressive muscle relaxation exercises in addition to routine postoperative care for 30 minutes per day over three consecutive days, while the control group will receive routine care only. Outcome measures will include dyspnea assessed by the Modified Borg Scale, anxiety assessed by the State-Trait Anxiety Inventory, hemodynamic parameters obtained from vital signs, and delirium symptoms assessed using the Nursing Delirium Screening Scale. It is hypothesized that the combined intervention will reduce dyspnea and anxiety levels, improve hemodynamic stability, and decrease delirium symptoms. The findings are expected to contribute to improved postoperative recovery and reduced complication risks following cardiac surgery.
