Abstract
Objective: To assess the dose response relationship of
incentive spirometer on lung compliance among postcoronary artery bypass grafting (CABG) patients.
Methodology: This Quasi Experimental study was
conducted at Begum Akhtar Memorial Hospital,
Bahria, Islamabad and included 45 patients. Nonprobability 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 PrePost 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.
Keywords: Incentive spirometer, coronary artery
bypass grafting (CABG), dose response relationship.
