AirLife spirometer (Dubuque)

This is a lightweight handheld device used for deep breathing therapy to improve lung function after surgery or illness. It helps strengthen your lungs by requires 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. Requires no energy but your own. Like new.
