POWERbreathe K5

The POWERbreathe K-Series features Auto-Optimising Inspiratory Muscle Training (IMT) that automatically adapts to your own personal training requirements.

Why is this beneficial?

When your lungs are empty, your muscles are at their strongest. As they fill up with air, they gradually lose strength. Physiologically, this is to stop you being able to over-inflate your lungs. If you put a strong resistance against the in-breath, you will only be able to exercise the inspiratory muscle for the first part of the breath. The POWERbreathe K-Series automatically changes the resistance/load, decreasing gradually to match the strength curve of the breathing muscles during an entire breath to maximise the training effect and results.

The POWERbreathe training regime of 30 breaths twice a day, typically takes only a few minutes a day, and when used correctly you should start to feel the benefits within just a few weeks.

POWERbreathe is drug-free and natural with no side effects or drug interactions.

  1. A history of spontaneous pneumothorax (a collapsed lung that was not due to traumatic injury e.g. broken rib), as it may lead to a recurrence of the condition.
  2. Pulmonary hypertension or large bullae on chest x-ray.
  3. Marked osteoporosis with history of rib fractures.
  4. Desaturation during or following IMT (<94%).


Inspiratory muscle training, such as training with POWERbreathe, is not recommended for patients with certain conditions, including the following:

  • Patients who have undergone recent abdominal surgery and those with an abdominal hernia.
  • Asthma patients who have a very low symptom perception and suffer from frequent, severe exacerbations or with an abnormally low perception of dyspnoea
  • If a patient is suffering from a ruptured eardrum or any other condition of the ear
  • Patients with marked elevated left ventricular end-diastolic volume and pressure
