Background:Respiratory complications are among the most common causes of morbidity and mortality after cardiac surgery. Decreased oxygenation of arterial blood has been recognized as a postoperative complication after mitral valve replacement.Purpose:to determine arterial blood gases response to different deep breathing maneuvers after mitral valve replacement. Method:Forty patients from both sexeswho underwent MVR with age ranged from 20to 30 years old participated in this study. The practical work was recruited atthe surgical department at National Heart Institute. They were assigned into two groups equal in number: group A:included twenty patients (10 men and 10 women) who performed breathing exercises without resistance by using I.S in the form of 30 deep breaths( three sets of 10 deep breaths each set performed for 60-90sec and with a 30- 60 second pause between each set ). Then after 5 hours from using IS they performed breathing exercises against resistance by using IMT in the form of 30 deep breath (three sets of 10 deep breaths each set was 60-90sec and with a 30- 60 second pause between each set).group (B):included twenty patients (10 men and 10 women) who performed breathing exercises against resistance by using IMT in the form of 30 deep breaths (three sets of 10 deep breaths each set was 60-90sec and with a 30- 60 second pause between each set). then after 5 hours from using IMT they performed breathing exercises without resistance by using I.s in the form of 30 deep breaths three sets of 10 deep breaths each set was 60-90sec and with a 30- 60 second pause between each set
