Abstract
Objective: To assess the dose response relationship of incentive spirometer on lung compliance among post-coronary artery bypass grafting (CABG) patients.
Methodology: This Quasi Experimental study was conducted at Begum Akhtar Memorial Hospital, Bahria, Islamabad and included 45 patients. Non-probability purposive sampling technique was used. Via PEFR meter Peak Expiratory Flow was taken and with IS Forced Expiratory Volume in 1 minute and Forced Vital Capacity were measured. Incentive Spirometer was performed
Results: Pre and post session PEFR, FEV1 and FVC of Groups A, B and C showed that p-values of Pre- Post 1st session, Pre-post 2nd session were not statistically significant.
Conclusion: Incentive Spirometer although can be clinically effective, but further studies are needed to quantify specific dosage of IS.
Key words: Incentive Spirometer, lung compliance, pulmonary complications.
