Background: Patients post-cardiac surgeries are developed restrictive pulmonary impairment
postoperatively. Different respiratory modalities are used to reduce pulmonary complications. Aim: to compare
between patients using different respiratory modalities post-cardiac surgeries regarding pulmonary complications
rate. Design: Descriptive comparative research design. Subject: 150 patients post-cardiac surgeries, divided into
three groups (A, B & C), 50 for each group. Group (A) practiced deep breathing and coughing exercises, Group (B)
used incentive spirometer and the group (C) used all previous respiratory modalities. Setting: This study was
conducted at cardiovascular hospital affiliated to Ain Shams University. Tools: Patients' demographic & clinical
data form and postoperative pulmonary complications assessment sheet. Results: The studied patients post-cardiac
surgeries in group (C) who practiced different respiratory modalities had lower post-operative pulmonary
complications rate than the patients in other groups (A & B) with statistical significant difference ? < 0.01.
Conclusion: Using of different respiratory modalities had significant positive effective on reducing post-operative
pulmonary complication rate among patients post-cardiac surgeries. Recommendation: the importance of using
different respiratory modalities for all patients' post-cardiac surgeries in other setting.
