Threshold IMT/PEP


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.


  • Flow independent one-way valve
  • Works in any position for effective therapy
  • Constant pressure removes the need for a pressure indicator
  • Convenient and reliable design
  • Mouthpiece
