Incentive spirometers are used to help patients improve the functioning of their lungs.The breathing exercises are designed to help patients take long deep breaths, similar to a yawn. The deep breathing improves the ability to clear mucus from the lungs and may also increase the amount of oxygen getting into the lungs.

The Coach 2 4000 Incentive Spirometer makes incentive spirometry easier for patients and clinicians alike.

The one-way valve ensures patients inhale, rather than exhale into the unit. Highly-visible pistons and universal graphics (indicating correct inspiratory flowrate) help patients perform and monitor their own post-surgical breathing exercises without direct supervision. Other features include an O2 connection for supplemental oxygen, convenient handle, flexible popple tubing and bedrail holder.
