The POWERbreathe K-Series is the 3rd generation of POWERbreathe Inspiratory Muscle Trainers (breathing trainers) and the world’s first portable precision electronic inspiratory muscle training and monitoring system. POWERbreathe K-Series is rechargeable and supplied with a recharging and display stand.

The POWERbreathe K-Series uses the basic principles of resistance training – just as you might use weights to strengthen your arm muscles, breathing in through POWERbreathe against the electronically controlled, rapid-response valve creates a resistance to inhalation – thereby increasing inspiratory muscle strength and endurance.

The POWERbreathe K3 training resistance is specifically designed to match the dynamic changes in breathing muscle strength throughout your breath and can automatically adapt to increases in your inspiratory muscle strength at the beginning of each training session. Training measurement results are displayed on the screen, allowing you to monitor training progress and to optimise your training technique.

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.

Cleaning your K3

Your POWERbreathe will be exposed to saliva during use. We recommend that a few times a week you remove the valve head and soak it in warm water for about 10 minutes (see POWERbreathe Manual for full details), but once a week soak the valve head in a mild sterilising solution instead of water, using these POWERbreathe Cleansing Tablets – only 1 tablet is required each time

Precautions & Contraindications

  • The patient must not make changes to any prescribed medication or prescribed treatment programme without consulting their doctor.
  • The K-Series devices are not intended for use by persons with reduced physical, sensory or mental capabilities, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
  • Do not use the POWERbreathe whilst taking part in other activities where you may become distracted, such as walking, running and driving.
  • If you have a pacemaker or other medical implant containing magnets or electronics, please consult with your doctor before using the POWERbreathe K-Series devices.
  • POWERbreathe should not be used if the patient is suffering from a ruptured eardrum or any other condition of the eardrum.
  • It is not recommended to use POWERbreathe if you have suffered from or are likely to suffer from Costochondritis.
  • To prevent the potential transmission of infections, we recommend that POWERbreathe is not shared with other users, including family members.
  • This product is not intended to diagnose, treat, cure or prevent any disease.
  • POWERbreathe is designed for exercising the inspiratory muscles only. No other use is intended or implied.
  • Anyone who is under the age of 16 should only use POWERbreathe with supervision from an adult. POWERbreathe contains small parts and is not suitable for children under 7 years.
  • Whilst training with POWERbreathe the patient should feel resistance when inhaling but it should not be painful. If the patient feels pain whilst using POWERbreathe they should stop immediately and consult their doctor.
  • Some users may experience slight ear discomfort when training with POWERbreathe, especially if they are recovering from a cold. This is caused by inadequate equalisation of pressure between the mouth and ears. If symptoms persist, patients should consult their doctor.
  • If a patient is suffering from a cold, sinusitis or respiratory tract infection, we advise that they do not use POWERbreathe until symptoms have disappeared.
  • If you start to feel dizzy using POWERbreathe IMT, please pause until recovered and take longer gaps between breaths.

Healthcare Professional should take into consideration the following conditions before patients use POWERbreathe:

  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
  • Patients with worsening heart failure signs and symptoms after RMT / IMT
