Abstract:
1. A system for performing spirometry and pulmonary function testing comprising: a flow control adapter, an incentive spirometer, a tracheostomy tube and an exhalation spirometer that measures forced expiratory volume, the flow control adapter further comprising a subject port adapted to be in fluid communication with an airway of a tracheostomized patient and directly coupled to the tracheostomy tube, an inspiratory port directly coupled to the incentive spirometer, an expiratory port coupled to the exhalation spirometer, and an adapter body that defines an inspiratory fluid flow path between the inspiratory port and the subject port and that defines an expiratory fluid flow path between the subject port and the expiratory port during use, the adapter body including: an inspiratory one-way valve positioned within the adapter body and coupleable to the inspiratory port such that the inspiratory one-way valve substantially prevents air that flows substantially along the inspiratory fluid flow path from flowing through the inspiratory port during expiration; and an expiratory one-way valve positioned within the adapter body and coupleable to the expiratory port such that the expiratory one-way valve allows air flowing substantially along the expiratory fluid flow path to flow through the expiratory port during expiration.
