Afflovest Clinicial Support & Evidence
Tactile Medical is committed to providing clinical evidence to support our products. View a collection of recently completed clinical studies on HFCWO therapy vests and their impact on lung function scores, spirometry measurements, EMI output and noise production.
Reduction in Antibiotic Use, Emergency Visits and Hospitalizations in COPD/Bronchiectasis Patients after Initiating AffloVest® HFCWO Therapy
In a recent study, COPD and bronchiectasis patients using AffloVest high frequency chest wall oscillation therapy showed reduced hospitalizations for respiratory causes and better overall respiratory health.
Clinician’s Data Analysis: Lung function improvement maintained over 16 to 24 months with use of AffloVest™
Ongoing data collected for this clinician paper was collected from the same five patients after 16 to 24 months of treatment using the AffloVest. The data collected on the five AffloVest patients shows that lung improvement overall was maintained over that total time period.
AffloVest® Demonstrates Improved Lung Function in Patients with Cystic Fibrosis
In the following case study, five adolescent patients used the AffloVest by Tactile Medical for 3–5 months each and saw increased Pulmonary Function Test (PFT) scores. The objective of the study was to measure lung function scores before and after use to determine efficacy.

Effect of High Frequency Chest Wall Oscillation Vests on Spirometry Measurements
Dr. Thomas O’Brien performed this study to investigate the effects of the short-term application of motor and compressor-based HFCWO vests on the spirometry parameters and to assess if there were significant differences between the two device types.
