About this study

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.

Primary outcomes

  1. Tidal Volume (TV) Assessed in Participants at Baseline and With Both Devices

    Time frame: 30 minutes

    Tidal Volume is the normal volume of air displaced between normal inhalation and exhalation, measured using standard sprirometry techniques

  2. Peak Expiratory Flow (PEF) Assessed in Participants at Baseline and With Both Devices

    Time frame: 30 minutes

    Peak Expiratory Flow (PEF) measures the peak flow during a forced exhalation, measured using standard spirometry techniques

  3. Forced Vital Capacity (FVC) Assessed in Participants at Baseline and With Both Devices

    Time frame: 30 minutes

    Forced Vital Capacity (FVC) is the total amount of air exhaled during the FEV test, measured using standard spirometry techniques

  4. Forced Expiratory Volume (1 Second) Assessed in Participants at Baseline and With Both Devices

    Time frame: 30 minutes

    Forced 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

  5. Forced Expiratory Flow (FEF25-75%) Assessed in Participants at Baseline and With Both Devices

    Time frame: 30 minutes

    Forced 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
