Success Story: Australian Police Diver

…Required to exhale more than 75% of my lung’s capacity in the 1st second of exhalation (FEV1) to pass my commercial dive medical…):

…The PowerLung machine is going well with very high recommendations on my part. I recently had great results in my lung function test (from 67% to 82%!!!!) I have not in the years past been able to produce such high results despite my level of fitness or activity. As a Police Diver I am required to undertake a commercial dive medical which is of high standard and it was a relief to pass the lung function test with ease for the first time ever.
