  1. Bench testing conducted in 2017. Testing was performed at the following therapy settings: The Vest® System Model 105 and the Monarch® System Model 1000 with intensity/pressure set at 10, frequencies settings at 5, 14, and 20 Hz; the AffloVest® System was tested at the “Vibration” setting at “Low”, Medium” and “High” settings, which according to the AffloVest® web site operate at 5Hz, 13Hz, and 20Hz respectively. The AffloVest® Systems used were labeled as REF 8200 and 8300. Testing consisted of measuring impulse force, or applied force over a timeframe of 30 seconds, via 4 force sensors placed on a mannequin in upper and lower chest locations. Comparisons are not based on head to head clinical efficacy or safety studies.
  2. Independent lab testing conducted in 2017. Data was analyzed and compared average pulse airflows at the mouth generated by high frequency chest wall oscillation (HFCWO) therapy in 10 human subjects using home care garments. Airflows were measured via pneumotachometer at settings of the following: The Vest® System Model 105 and the Monarch® System Model 1000 with intensity/pressure set at 10, frequencies settings at 5, 10, 15, and 20 Hz; the AffloVest® System was tested at the “Vibration” setting at “Low”, Medium” and “High” settings, which according to the AffloVest® web site operate at 5Hz, 13Hz, and 20Hz respectively. The AffloVest® Systems used were labeled as REF 8200 and 8300. Comparisons are not based on head to head clinical efficacy or safety studies. Airflow test subjects were adult males with healthy lung function. Results for female subjects and patients with lung disease may vary from those in this study.
