The Mediflo Duo is a single patient use incentive spirometer and can be used for two types of respiratory therapy: Sustained Maximal Inspiration (SMI) and Positive Expiratory Pressure (PEP). SMI is an inhalation exercise performed by breathing in slowly, continuously and as deeply as possible. PEP is an exhalation exercise performed by slowly breathing out against an expiratory resistance.

Resistance to flow is easily adjusted to perfectly fit each patient’s physical ability. Monitor improvement with the resistance indicator scale and increase therapy compliance.

 With only a few adjustments the Mediflo Duo can be transformed from a respiratory exerciser for inspiration exercises to a breathing trainer for expiration exercises.
