POWERbreathe KH2

Breathe-Link Medic Live Feedback Software

£1,020.00

POWERbreathe KH2 with Breathe-Link Medic Live Feedback Software provides inspiratory muscle training, instant monitoring and live feedback analysis for respiratory muscle training programmes for patients with dyspnoea, including patients with asthma, COPD, bronchitis, cystic fibrosis, emphysema, heart disease, neuromuscular disease, Parkinson’s disease and spinal injury.

KH2 Quality Control MIP Test:

To ensure accurate and repeatable MIP results, the POWERbreathe KH2 Breathe-Link Medic Live Feedback software has introduced the QC (Quality Control) MIP test: The maximum value of 3 manoeuvres that vary by less then 20% is recorded. When a patient is unable to complete a MIP test, the PIF test is a useful alternative.  

POWERbreathe KH2 can be utilised by healthcare professionals in the clinic using hygienic disposable filters, or by patients themselves for single patient use at home under medical supervision.

KH2 Features:

  • Auto-optimising IMT - automatically adapts to training requirements
  • Training Intensity - can be set to ‘auto’ or ‘manual’ for increasing/decreasing load intensity (cmH2O)
  • Training Guidance - guides breathing at an appropriate rate
  • Training Results - scroll between results for Load, Power, Volume, Flow Rate and Energy
  • Strength Index – calculates inspiratory muscle strength (cmH2O) based upon PIF
  • MIP/PIF RMT - Maximum Inspiratory Pressure and Peak Inspiratory Flow tests for inspiratory muscle assessment 
  • Endurance Programme – perform a 150-breath session to completely fatigue the inspiratory muscles
  • Breathing Energy – measures mechanical work of breathing during a session, combining force exerted and volume inhaled
  • Breathe-Link Medic Live Feedback Software - captures, organises and stores data and analysis of the respiratory muscles’ performance

TEST MODES

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 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.

The POWERbreathe KH series uses piezo-resistive pressure sensing technology for precise measurement of respiratory pressure 500 times/second. The triple-aperture rotary valve system makes up to 4000 precision movements every second.

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. 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.

This study concluded that the K-Series device "provides automatically processed and valid estimates of physical units of energy during loaded breathing tasks..."

How to use:

  1. The patient puts the nose-clip on so that it pushes their nostrils together (this is optional but prevents the patient from breathing in through their nose).
  2. The patient should then breathe in quickly and forcefully through POWERbreathe for 30 breaths twice a day (preferably morning and night to allow the inspiratory muscles time to recover in between sessions). This is the scientifially proven training regimen.
  3. As inspiratory muscle strength and stamina improve, the patient may adjust and increase the resistance.
  4. Full instructions are provided in the accompanying user manual.

Cleaning:

The POWERbreathe KH2 should be used in conjunction with disposable bacterial/viral filters for multi-patient use. For single patient use, please follow the guidelines below to ensure that the POWERbreathe KH2 remains hygienic and in good working order.

  1. POWERbreathe will be exposed to saliva during use. After each training session, remove the Valve Head from the POWERbreathe KH2 and soak it in warm water for about ten minutes. Now hold the valve head under warm running water whilst opening and closing the valve to aid cleaning of the valve surfaces. Shake off excess water and leave on a clean towel to dry ( the POWERbreathe Manual has full details).
  2. Once a week POWERbreathe should be soaked in a mild cleansing solution instead of water, using  POWERbreathe Cleansing Tablets - only 1 tablet is required each time. After cleaning, hold the valve head under a running tap allowing water to run through it. Shake off excess water and leave on a clean towel to dry.

Wipe-clean the POWERbreathe handset with a damp cloth. Do not immerse the handset or expose it to running water as this may damage the internal electronics.

NOTE: Never use scouring pads, abrasive cleaning agents or aggressive liquids such as petrol or acetone to clean the appliance. POWERbreathe KH2 is not suitable for dishwasher or autoclave use.

POWERbreathe 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 is used safely and appropriately.

Precautions:

  • The patient must not make changes to any prescribed medication or prescribed treatment programme without consulting their doctor.
  • POWERbreathe should not be used if the patient is suffering from a ruptured eardrum.
  • To prevent the potential transmission of infections, we recommend that patients do not share the POWERbreathe K-Series mouthpiece or valve head 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.
  • POWERbreathe KH-Series is 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.
  •  If the patient feels light headed or dizzy whilst training with POWERbreathe, they should slow down their rate of breathing or pause until they have fully recovered.
  • Patients with a pacemaker or other medical implant containing magnets or electronics should consult their doctor before using this product.
  • POWERbreathe is manufactured in a hygienic environment. However, POWERbreathe is not provided sterile – we recommend that the mouthpiece be cleaned prior to use.

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
