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.
