Common causes of dyspnoea in athletes

This article published in the European Respiratory Society’s June issue of Breathe explains how dyspnoea, (shortness of breath or breathlessness), during exercise is a common complaint in seemingly otherwise healthy athletes, and which may be associated with fatigue and underperformance. As dyspnoea may be caused by numerous factors, from poor aerobic fitness to serious, potentially fatal respiratory and nonrespiratory pathologies, the article explains why it is important for clinicians to obtain an appropriate case history and ask relevant exercise-specific questions to fully characterise the nature of the complaint so that a targeted diagnostic plan can be developed for the athlete. The article looks into asthma and exercise-induced bronchoconstriction, and exercise-induced laryngeal obstruction and vocal cord dysfunction, the most common treatments for which have included diaphragmatic breathing control. Even for those athletes experiencing expiratory flow limitation it is suggested that this could be overcome through controlled breathing methods or respiratory muscle training.

POWERbreathe respiratory muscle training (RMT) strengthens the breathing muscles, improving their stamina and reducing fatigue. POWERbreathe RMT has been clinically proven to reduce dyspnoea during exercise and daily activities, as well as improving exercise tolerance and quality of life particularly in patients with COPD (see References below.).

K-Series Selected For Front Cover Of ERS Buyers Guide

The ERS (European Respiratory Society) Buyers’ Guide Editor selected (at no cost) the POWERbreathe KH-Series to feature on the front cover of the ERS Buyers’ Guide for 2011 / 2012.

The Buyers’ Guide provides respiratory clinicians with an up-to-date source of information about respiratory products and devices that are transforming the lives of patients with respiratory illness and disease.

The patented POWERbreathe KH-Series and other respiratory care products by POWERbreathe were featured in a full-page of evidence based, drug-free breathing rehabilitation and training products.

POWERbreathe was delighted to have the KH-Series selected for the front cover as the KH-Series represents a revolution in respiratory muscle training with its piezo-resistive pressure sensing technology for the precise measurement of respiratory pressure 500 times/second. The KH-Series’ triple-aperture rotary valve system makes up to 4000 precision movements every second.

POWERbreathe has been recognised in providing ‘Gold Standard’ K-Series devices for important research in a multi-nation COPD study, reporting,

“We conclude that the handheld device provides automatically processed and valid estimates of physical units of energy during loaded breathing tasks. This enables health care providers to quantify the load on inspiratory muscles during these tests in daily clinical practice.”

The printed version of the ERS Buyers’ Guide was distributed to 20,000 delegates who attended the ERS Annual Congress.

A New Device For IMT In Patients With Tracheostomy Tube In ICU: A Randomized Trial

The objective of this randomised controlled trial was to compare the inspiratory muscle strength between two groups of tracheostomy patients: Inspiratory Muscle Training with POWERbreathe and breathing through a humidified t-piece (T-tune).

POWERbreathe KH2 promotes increased muscle strength in tracheostomy patients

Following another successful ERS (European Respiratory Society) Congress this year, the European Respiratory Journal has published Abstracts from the 24th International Congress in their Official Scientific Journal.

We’re delighted to be able to share this paper Abstract with you (Eur Respir J 2014; 44: Suppl. 58, page 2, Abstract No. 4297) which concluded that the new and soon to be launched POWERbreathe KH2 “promotes increased muscle strength in tracheostomy patients”.

Here’s the Absract…

Background: Evaluation and training of the respiratory muscles are essential to reducing time of weaning invasive mechanical ventilation (VMI) in intensive care units (ICU). Powerbreathe® is indicated for inspiratory muscle training (IMT) with a progressive resistance and adjustable load in respiratory disease patients.

Objective: Compare the inspiratory muscle strength between two groups of tracheostomy patients: IMT with Powerbreathe® and breathing through a humidified t-piece (T-tube).

Methods: 25 tracheostomy patients were selected under VMI and randomized into two groups: T-tube (control) and IMT with Powerbreathe®. Patients of both groups received respiratory physical therapy and the MIP measurements with a digital manometer (MVD300, Globalmed®), with a one-way valve connected to tracheostomy, with occlusion for 20 seconds. In control group patients underwent T-tube until complete 48 hours of continuous nebulization. In the IMT group was used Powerbreathe® KH2 model (Powerbreathe®, POWERbreathe International Ltd., England) for 30 cycles (three sets of 10 cycles with 1 minute interval between them), adjusted load 30% of the initial MIP, increasing 10% daily. For statistical analysis, were applied Wilcoxon test for comparison of related and Mann-Whitney test for independent samples variables. P values <0.05 were considered statistically significant.

Results: Of 19 patients, 8 in the IMT group with 7 men and 11 in the control, with 8 men. Were increased final MIP compared to initial in IMT group (p=0.017), with no significant difference for the control group (p=0.304).

Conclusion: The IMT with Powerbreathe® in tracheostomy patients promotes increased muscle strength.


POWERbreathe at European Respiratory Society Congress 2013

Earlier in September POWERbreathe attended the 23rd Annual ERS Congress in Barcelona where 10,000 delegates with an interest in respiratory health and disease from around the world came to learn more about raising awareness of lung health and improve prevention, management and treatment of respiratory diseases.

The objective of the ERS Congress is to share knowledge and in turn to “alleviate suffering from respiratory disease” which the congress does by ensuring every aspect of respiratory research is covered; from basic research to clinical practice to intensive care.

The new edition of the ERS’s European Lung White Book was announced at the congress by Professor John Gibson who said: “We hope that this White Book will help to inform decision making about the future provision of healthcare for patients with respiratory disease and to highlight the conditions for which more facilities and resources are likely to be required, as well as areas where further research is most needed”.

Included in the White Book is a chapter on Pulmonary Rehabilitation that looks at other interventions, including respiratory muscle training which, it says, ‘increases the strength and endurance of the respiratory muscles.’ It goes on to say, ‘A recent meta-analysis showed that inspiratory muscle training improves muscle strength and endurance, functional exercise capacity, dyspnoea and HRQoL in COPD patients.’

Reflecting on what needs to be done in order to prevent the rise of respiratory diseases in the future, ERS has produced a forward-looking Roadmap outlining the necessary action.

The ERS Roadmap for Healthcare Professionals offers recommendations for the future of respiratory medicine and in Chapter 1, Prevention, explains how “most of the chronic disability and death in Europe can be accounted for by four major health determinants:

1. Tobacco
2. Physical inactivity
3. Alcohol
4. Poor diet

ERS says, “We need to develop robust and simple methods to screen for sleep breathing disorders, lung cancer, chronic obstructive pulmonary disease and other chronic respiratory conditions as well as respiratory infections, as these will remain significant challenges at the clinical level. More effective screening would enable us to anticipate respiratory health burdens of the future.”

“Research and innovation are crucial to our understanding, optimal management and future treatment of respiratory disease.”

And this is why every year POWERbreathe attends the ERS Annual Congress: to be a part of a team with the same objective, of helping to make a difference to those people with respiratory conditions by improving their quality of life, and for us it’s through respiratory muscle training with POWERbreathe.
