Which position is recommended when using an incentive spirometer?

• A. Sitting in high Fowler's or upright position
• B. Lying on the side with head tilted
• C. Standing with feet together
• D. Sitting with a reclined back

Answer: (A)

Position affects how fully the lungs can expand during a deep breath. An incentive spirometer works best when the patient can take slow, sustained, deep breaths to open collapsed airways and increase ventilation. Sitting upright, especially in high Fowler's position, allows the diaphragm to descend fully and the chest wall to expand more completely. This increases inspiratory capacity and improves the effectiveness of the device, helping prevent atelectasis after surgery or during limited activity. Lying on the side with the head tilted can restrict symmetric chest expansion; standing with feet together isn’t as stable or practical for patients recovering and may not optimize breathing mechanics; sitting with a reclined back limits chest wall expansion and diaphragmatic movement. So, the upright position is the best choice for using an incentive spirometer.
