Effect of High Frequency Chest Wall Oscillation Vests on Spirometry Measurements

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.

About this study

The study will be broken into three (3) arms:

  • AffloVest® & The Vest®
  • AffloVest® & inCourage®
  • AffloVest® & SmartVest® Subjects will be randomly assigned to an arm. Within each arm, the order of products will be also 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 Compressor-based vest) 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. TV

    Time frame: 30 minutes

    Tidal Volume, the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied

  2. PEF

    Time frame: 30 minutes

    Peak Expiratory Flow, a person's maximum speed of expiration

  3. FVC

    Time frame: 30 minutes

    Forced Vital Capacity, the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible

  4. FEV1

    Time frame: 30 minutes

    Forced Expiratory Volume, the volume of air that can be forced out in one second after taking a deep breath

  5. FEF25-75%

    Time frame: 30 minutes

    Forced Expiratory Flow (25-75%), the peak expiratory flow at 25 - 75% FVC
