Threshold IMT/PEP

Overcome the pressure for consistent IMT and PEP therapy



The Threshold IMT (Inspiratory Muscle Trainer) and Threshold PEP (Positive Expiratory Pressure Device) are two innovative products that provide consistent and specific pressure, regardless of how quickly or slowly patients breath. 

The IMT is designed to increase respiratory muscle strength, respiratory muscle endurance and exercise tolerance.

The PEP prevents accumulation and mobilisation of secretions and promotes effective breathing patterns.  It improves gas exchange and improves central and peripheral airway function.
