AirLife spirometer (Dubuque)

This is a light-weight hand-held device used for deep breathing therapy to improve lung function after surgery or illness. It helps strengthen your lungs by requiring you to take slow, deep breaths to make a piston lift to a target level on its display tube. It has clear calibrations, an adjustable goal indicator, flexible tubing, and a mouthpiece for a proper seal. Needs no energy but your own. Like new.
