CHEST

CHEST M.I. is a Japanese respiratory medical device company focused on pulmonary diagnostics and home respiratory care. Founded in 1965, the company develops and markets spirometers, pulmonary function testing systems, forced oscillation technique devices, pulse oximeters, and related accessories and software. Its products are used for evaluation and management of respiratory conditions including asthma and chronic obstructive pulmonary disease, and its business description also includes ventilators, oxygen concentrators, CPAP, and polysomnography in Japan. The company appears to operate as a commercial-stage healthcare company rather than a therapeutic drug developer, with revenue derived from marketed medical devices and respiratory-care products.
