Aim: To find the effectiveness of BBT versus Incentive Spirometry on reducing PPCs after CABG which will cause reduction in hospital stay and overall cost of CABG Methodology: A Quasi Experimental study design consisting of reviews of charts of CABG patients over the age of 60 years. All the patients are presented with post-operative Coronary Artery bypass Graft. Pre- and Post-Treatment scores of Breath hold are assessed to know their breathing capacity by Control Pause Test (CP). Results: The pre and posttest values were assessed by breath holding in Group A and Group B. The mean difference value, standard deviation, paired ‘t’ test and unpaired ‘t’ test were calculated and compared with table value. Conclusion: The paired ‘t’ test values have shown that BBT and IS technique has a better effect than the IS and thereby on reducing PPCs after CABG which will cause reduction in hospital stay and overall cost of CABG.
