well yes and no. incentive spirometers generally are used by patients after surgery or by people who suffer from an injury (such a fractured rib) that causes them not to breathe well or deeply. as you slowly breathe in through the spirometer it causes inflation of the small sacs in the lungs called alveoli. inflating the alveoli helps keep them free of fluid build-up. fluid build-up in the alveoli can lead to pneumonia. in a healthy individual using an incentive spirometer could theoretically increase air flow which would aid in lung function. studies have not shown that using an incentive spirometer increases or improves lung function in individuals with chronic pulmonary obstructive disorder (copd) or other chronic lung problems. i hope this is helpful!
can spirometers improve lung function
