Abstract
Background: The patients who have done CABG are prone to pulmonary complications. Various physiotherapy management is present for prevention of lung complication. Literature shows lots of technique as treatment of choice, incentive spirometry is one of them. AIM: To asses immediate effect of incentive spirometry on arterial blood gas analysis in patient recently underwent coronary artery bypass surgery. Method: There was 30 patients. Blood was drawn from arterial line for pre-treatment ABG. Incentive spirometry was given 10 reps and 3 sets. Patient was prop up 30-40 degree. Romsons tri colour volume spirometry is used. Mouthpiece was placed in patient's mouth and made a good seal over the mouthpiece with lips. Exhaled through nose normally then breathe in slowly through mouth. Ball in the incentive spirometer will go up. The patient to hold or rise the ball as high as possible and hold it for 3 or 5 seconds the slowly exhale. This was done for 10 to 15 times. Blood was drawn from arterial line for post treatment ABG. Result: There was statistically extremely significant change in value of PaO2 (112.54 ±39.46 vs133.01 ±42.13) p value <0.0001, PaCO2 (38.75 ±4.2 vs 36.9 ±3.7) p value 0.0003 and SaO2 (96.8 ±1.84 vs 98.93 ±1.11) p value <0.0001 Conclusion: This study shows that there is immediate effect of Incentive Spirometry on ABG analysis in CABG surgery patient by significant improvement of PaO2 and SaO2 and decrease in PaCO2.
