Completed Studies With the WellO2 Breathing Trainer

Effects of counterpressure breathing with steam inhalation on lung function in stable asthma

Significant Findings: Light counter-pressure breathing training combined with steam breathing for four weeks increases respiratory muscle strength and vital capacity (VC) in patients whose asthma and medication are under control.

The following values measured at the end of the experiment improved significantly more in group A than in group B: MEP (mean +12.4%, vs. +3.5%, p=0.047), MIP (mean +20.1% vs. +0.82%, p=0.046), VC (mean +3.7 % vs. 1.5%, p=0.017) and FET (mean +15.5%, vs. -5.0%, p=0.024.). In group A, the improvement from baseline values was very significant: MEP (p=0.004), MIP (p<0.001), VC (p<0.001) and FET (p<0.001). No adverse effects from training were detected.
