Philips Respironics Threshold IMT

Threshold IMT provides consistent and specific pressure for inspiratory muscle strength and endurance training, regardless of how quickly or slowly patients breathe. This device incorporates a flow-independent one-way  valve to ensure consistent resistance and features an adjustable specific pressure setting (in cm H20) to be set by a healthcare professional. When patients inhale through Threshold IMT, a spring-loaded valve provides a resistance that exercises respiratory muscles through conditioning.

  • Flow-independent one-way valve
  • Constant pressure (regardless of patient’s airflow) eliminates the need for a pressure indicator
  • Easy to set, truly adjustable pressure (2 cm H2O increments)
  • Effective therapy when held in any position
  • Can be used with mouthpiece or mask
  • Easy to clean
  • Made of durable, high-impact acrylic
  • Increases respiratory muscle strength 1
  • Increases respiratory muscle endurance 1
  • Increases exercise tolerance 1
