An incentive spirometer is a handheld medical device used to help patients improve the functioning of their lungs. By training patients to take slow and deep breaths, this simplified spirometer facilitates lung expansion and strengthening. Patients inhale through a mouthpiece, which causes a piston inside the device to rise.
The iron lung, also known as the tank ventilator, Drinker tank or Emerson tank, was the first common pure-NPV device when it was developed in the 1920s by Drinker, Shaw and Mason.

Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation. The process by which oxygen is taken in by the bloodstream is called oxygenation. Lung compliance is the capacity of the lungs to contract and expand.
Measurements of lung function can vary both within and among groups of people, individuals, and spirometer devices. Lung capacity, for instance, may vary temporally, increasing and then decreasing in one person's lifetime.

The (FROPVD) has a peak flow rate of 100% oxygen at up to 40 liters per minute. To use the device, manually trigger it until chest rise is noted and then release. [2] Wait five seconds before repeating. The device must have a pressure relief valve that opens at 60cm of water pressure to avoid over ventilation and trauma to the lungs.
