Brief summary

The impact of high-frequency chest wall oscillation therapy on spirometry values (Forced Expiratory Volume, Forced Vital Capacity, Peak Expiratory Flow, Forced Expiratory Flow and Tidal Volume is investigated during use of several products and comparing to baseline values

Detailed description

The study will be broken into one (1) arm: • AffloVest® & Monarch™ Within the arm, the order of products will be randomized. Baseline spirometry (Forced Expiratory Volume (FEV1), Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF), Forced Expiratory Flow (FEF25-75%) and Tidal Volume (TV)) will be taken at the beginning, middle and end of each series of measurements with each subject, without any device on the subject. A product (AffloVest or Monarch) will be placed onto subject and turned ON to the highest frequency and intensity settings. Then the subject will be given a certain period of time to adjust and spirometry measurements will then be repeated, then the product will be removed and the subject will be allowed a recovery period, then the other product will be placed on the subject, turned ON and spirometry measurements will repeated.

Forced Vital Capacity (FVC) Assessed in Participants at Baseline and With Both Devices30 minutesForced Vital Capacity (FVC) is the total amount of air exhaled during the FEV test, measured using standard spirometry techniques
Forced Expiratory Volume (1 Second) Assessed in Participants at Baseline and With Both Devices30 minutesForced Expiratory Volume in 1 second (FEV1) measures how much air a person can exhale during a forced breath during the first one (1) second, measured using standard spirometry techniques
Forced Expiratory Flow (FEF25-75%) Assessed in Participants at Baseline and With Both Devices30 minutesForced Expiratory Flow (25-75%) is the average flow from the point at which 25% of the FVC has been exhaled to the point at which 75% of the FVC has been exhaled, measured using standard spirometry techniques
