Post-operative Incentive Spirometry Changes From Preoperative Baseline at 4-8 Hours Post-operative4-8 hours post-operativeIncentive spirometry measures how much air you can inhale, which can help indicate how well your lungs are working after surgery. Incentive spirometry measures the volume (or amount) of air you inhale measured in cubic centimeters (cc). Higher numbers indicate that you're inhaling more air. This measure will be the change in incentive spirometry from baseline (baseline incentive spirometry - incentive spirometry 4 to 8 hours post-operative).

Post-operative Incentive Spirometry Changes From Preoperative Baseline at 0-4 Hours Post-operative

Incentive spirometry measures how much air you can inhale, which can help indicate how well your lungs are working after surgery. Incentive spirometry measures the volume (or amount) of air you inhale measured in cubic centimeters (cc). Higher numbers indicate that you're inhaling more air. This measure will be the change in incentive spirometry from baseline (baseline incentive spirometry - incentive spirometry 0 to 4 hours post-operative). A negative number reflects reduced volume of air.
