Drug-Free IMT Reduces Use Of Asthma Inhalers

A recent report claims that switching to ‘green’ inhalers could reduce carbon emissions and cut costs. The study, led by researchers at the University of Cambridge, finds that metered-does inhalers contribute approximately 3.9% of the carbon footprint of the NHS. This is due to the hydrofluoroalkane (HFA) propellants found in these asthma inhalers. HFAs, like CFCs before them, are potent greenhouse gases. As a result, there is a call to switch to alternatives that have a lower carbon footprint.

Effective alternatives

The report suggests alternatives to metered-dose inhalers include dry powder inhalers and aqueous mist inhalers. However, these have a higher “up-front” price.

“It’s important to stress that patients shouldn’t stop using their usual treatments to reduce their carbon footprint. Instead we recommend patients review their condition and treatment at least annually with their healthcare professional and at this point discuss whether a more environmentally-friendly inhaler is available and appropriate in their situation.”

Dr Alexander Wilkinson, Consultant in Respiratory Medicine from East and North Hertfordshire NHS Trust.

IMT reduces asthma inhaler use

In other research, Inspiratory Muscle Training (IMT) reduces the number of puffs on asthma inhalers, from 3.9 to 1.6 per day.

Reduction in use of asthma inhalers

Three separate studies into the use of inspiratory muscle training in patients with asthma observe an average 51% reduction in β2-agonist consumption1,2,3. A further study2 finds a decrease in corticosteroid use by asthma patients ~80%. Beta agonists relax muscles of the airways while corticosteroids reduce airway inflammation.

Breathing not only presents a limitation to athletes but also impacts people with respiratory illness, such as asthma. It is this recognition that began research into Inspiratory Muscle Training.

POWERbreathe Medic for asthma

One such IMT device, the POWERbreathe Medic, is available for prescription in the UK by the NHS. It is an evidence-based, drug-free treatment for patients with difficult or laboured breathing, especially those with asthma, COPD and heart failure.

POWERbreathe International Ltd. Managing Director Harry Brar says:

“Because POWERbreathe IMT is drug-free it can be used in combination with traditional asthma medication.

“By using POWERbreathe IMT to strengthen their breathing muscles, asthma patients will find that their breathing technique improves too, enabling them to inhale their medication past the back of the throat to reach the areas where it can be of most benefit.”

Developed by scientists at leading UK universities, POWERbreathe IMT is being used in clinical trials for use in clinical medicine and home healthcare.

POWERbreathe Inspiratory Muscle Training is a recent topic of interest at the European Respiratory Society’s International Congress, Madrid. Furthermore, the pre-conference workshop at Transform uses the POWERbreathe device to demonstrate IMT. Transform is the physiotherapy conference in Adelaide, led by Rik Gosselink, Professor of Rehabilitation Sciences KU Leuven, PT Respiratory Rehabilitation, University Hospital Leuven.

New online resource for Asthma Management

The Asthma and Allergy Foundation of America have announced the launch of ‘Get Smart About Asthma’, a comprehensive online asthma management resource that takes a look at the underlying cause of asthma – inflammation.

You’ll find information about asthma triggers and asthma types; asthma tips for adults and children; a glossary; research and resources; how to control your asthma; and asthma treatments.

If you suffer with asthma, you’ll be familiar with the two types of medications you require: quick-relief medicine for immediate symptom relief during an asthma attack; and long-term control medicine for controlling inflammation in the airways.

The most common quick-relief medicine you’ll be familiar with is the inhaled short-acting bronchodilator, known as Short-Acting Beta Agonists (SAMA) that quickly relaxes tightened muscles in the airways allowing them to open. But did you know that in laboratory studies and randomised trials, inspiratory muscle training was shown to generate:

And did you know that 9% of people with asthma use complementary therapies for their asthma (Asthma UK 2012)?

In the randomised, controlled trials, on mild / moderate asthmatics, POWERbreathe inspiratory muscle training (IMT) increased inspiratory muscle strength by a mean of 11% in just 3 weeks.

And inspiratory muscle training has been shown to relieve the symptoms of asthma by improving lung function, resulting in reduction of medication and a fall in hospitalisations.

Asthma patients experience a reduction in dyspnoea (difficult or laboured breathing; shortness of breath) after as little as 3 weeks’ POWERbreathe inspiratory muscle training (IMT), as well as improvements in quality of life.

The Get Smart About Asthma website includes really useful online tools, including: Asthma Symptom Checker; Assess Your Asthma Control and Asthma Action Plan.

These online tools have been created to enable you to provide relevant information to your asthma nurse or healthcare professional when you visit for a consultation.

When you visit your doctor to discuss your asthma treatment it would be worth asking about the POWERbreathe Medic which is available for prescription in the National Health Service (NHS) UK Drug Tariff, and is being prescribed by UK medical professionals as either a standalone intervention or as part of a rehabilitation programme.
