In this part of the study the materials and methods will be presented under the following headings: subjects, equipments, procedures of the study and statistical procedures 1. Subjects. Ninty patients of both sexes will participate in this study with an age range of 40 to 50 years old. They will be chosen from outpatient clinic, Qena University Hospital. Patients will be randomely assigned into three groups: Group A: patients will receive a two supervised sessions using acapella device three sets for 10 repetitions from the first day postoperative until 7 days, in addition to routine physiotherapy program (phase I cardiac rehabilitation, breathing exercises, postural drainage, percussion and vibration. Group B: patients will receive a two supervised session using power lung device three sets for 10 repetitions two times daily from first day postoperative until 7 days, in addition to routine physiotherapy program (phase I cardiac rehabilitation, breathing exercises, postural drainage, Percussion and vibration). Group C. Patients will receive only routine physical Therapy program. 2. Equipment: 1\. For evaluation: Arterial blood gases including: - paO2, paCO2, PH and O2 saturation. Spirometry measurements: - as forced vital capacity (FVC) andbforced expiratory volume in the first second (FEV1). The incidence of PPCs and the length of postoperative stay: - using the Melbourne Group Scale Dyspnea. According to the revised or modified Borg scale or rating of perceived exersion. The Rand SF 36 health survey questionnaire. 2. For treatment The power lung device. Acapella device.
