The POWERbreathe KH2 with Breathe-Link Medic Live Feedback Software applies the tried and trusted principles of resistance (weight) training to the inspiratory muscles and can be thought of as ‘dumbbells for the diaphragm’. When the inspiratory muscles are overloaded regularly for a period of a few weeks, they adapt, becoming stronger and more resistant to fatigue. Activating stronger inspiratory muscles requires less effort during a given task, hence dyspnoea is reduced.
Dyspnoea, or breathlessness, is the main debilitating symptom of cardiorespiratory disease but it is also a common symptom in other conditions and in all cases, it has a profoundly impairing influence upon the quality of life and independence.
Strengthening the inspiratory muscles has a universally beneficial effect upon dyspnoea and dyspnoea can be improved by specific strength training of the inspiratory muscles.
KH2 Training Resistance
The POWERbreathe KH2 uses an electronically controlled, rapid-response valve to create a resistance to inhalation.
Training against this resistance causes the inspiratory muscles to adapt, becoming stronger and more resistant to fatigue. This leads to reduced breathlessness and improved exercise tolerance and quality of life.
As the patient breathes through the POWERbreathe KH2 you will notice that they gradually have to work harder to breathe in. This is the effect of resistance training acting on the inspiratory muscles (primarily the diaphragm and intercostal muscles). When breathing out, there is no resistance and the patient should breathe out normally, allowing the chest and breathing muscles to relax, naturally pushing the air from their lungs.
The POWERbreathe KH2 training resistance is specifically designed to match the dynamic changes in breathing muscle strength throughout the breath and can automatically adapt to increases in inspiratory muscle strength at the beginning of each training session.
How are results displayed?
Results are displayed on screen following a training or assessment session, or can be viewed in real-time using the Breathe-Link Medic PC software supplied. Parameters displayed include Maximal Inspiratory Pressure (cmH2O, highest 1 second average), Peak Inspiratory Flow (L/s), Training load (cmH2O), Average Power (Watts), Average inhaled volume (L) and Energy (Joules).
Training load is gradually introduced over the first five breaths of a training session. The first two breaths are unloaded. During these breaths, inhaled volume and flow are measured and used to set an appropriate training load.
Loading is then gradually introduced during breaths three and four until full loading is achieved for breath five and onwards.
The POWERbreathe KH2 training regime of 30 breaths, twice a day typically takes only a few minutes a day and, used properly, patients should start to observe the benefits within just a few weeks.

Advanced Personalised Variable Load Training
The patented POWERbreathe KH-Series has an electronically controlled resistance valve, that provides variable pressure threshold resistance, optimised to match the strength profile of the inspiratory muscles for maximum training effectiveness.
The POWERbreathe KH-Series Auto-optimising Inspiratory Muscle Training system automatically adapts to the patients personal training requirements.
Manual Training Intensity
This training intensity adjustment option allows resistance to be manually set from 5 to 200cm H2O to suit the patient’s personal training requirements.
The KH-Series training guidance system provides breathing pacing guidance, displays the number of breaths remaining in a training session and informs you when the session is complete.
Allows up to 150 breaths training stimulus to the respiratory/inspiratory muscles.
MIP Test with Breathe-Link Medic Software
Maximum Inspiratory Pressure (MIP) test. A test that measures the strength of the muscles used in breathing.
Real-time / Live feedback provides healthcare professionals with a detailed analysis of each breath to help respiratory and pulmonary rehabilitation assessment.
Predicted Normal Value Band. Highest One Second Average is your MIP score for the current breath.
S-Index / PIF Test Live Session
Strength index is a measure of the patient’s inspiratory muscle strength, based on the relationship between pressure and flow. PIF (Flow) is a measure of the maximum rate at which the patient can inhale air into their lungs.
This measurement is based upon the maximum measured flow rate during the test breath, which gives an indication of the speed at which the patient’s inspiratory muscles contract.

POWERbreathe IMT is drug free, suitable for almost anyone and should cause no harmful side effects when used properly. Please read the following precautions and contraindications to ensure that POWERbreathe IMT is used safely and appropriately.
- The patient must not make changes to any prescribed medication or prescribed treatment programme without consulting their doctor.
- A patient must not use the POWERbreathe IMT device whilst taking part in other activities where they may become distracted, such as walking, running and driving.
- POWERbreathe IMT 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 IMT if the patient has suffered from or are likely to suffer from Costochondritis.
- To prevent the potential transmission of infections, we recommend that POWERbreathe IMT is not shared with other users, including family members.
- This product is not intended to diagnose, treat, cure or prevent any disease.
- POWERbreathe IMT 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 IMT with supervision from an adult. POWERbreathe IMT contains small parts and is not suitable for children under 7 years.
- Whilst training with POWERbreathe IMT, the patient should feel resistance when inhaling but it should not be painful. If the patient feels pain whilst using POWERbreathe IMT, they should stop immediately and consult their doctor.
- Some users may experience slight ear discomfort when training with POWERbreathe IMT, 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 IMT until symptoms have disappeared.
- If a patient starts to feel dizzy using POWERbreathe IMT, please recommend that they pause until recovered and take longer gaps between breaths.
The Healthcare Professional should take into consideration the following conditions before patients use POWERbreathe IMT:
- 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.
- Pulmonary hypertension or large bullae on chest x-ray.
- Marked osteoporosis with history of rib fractures.
- 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:
- 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
- If a patient is suffering from a cold, sinusitis or respiratory tract infection, we advise that they do not use their POWERbreathe IMT device.
