Frequently Asked Questions


A. What is the difference between HFCWO and HFCC?

HFCWO (High Frequency Chest Wall Oscillation) and HFCC (High Frequency Chest Compression) are interchangeable terms that describe the same airway clearance therapy.

B. Is the AutoVest® only for patients with Cystic Fibrosis?

a. No, the AutoVest® may be prescribed by a physician for anyone with a disease or condition that requires aggressive airway clearance therapy for which HFCWO may benefit.

b. To date, HFCWO therapy has been prescribed by physicians for over 400 diagnoses.

C. Why is patient positioning not necessary as it is in manual Chest Physiotherapy (CPT)?

a. Unique single-hose design offers greater convenience and comfort

b. Full coverage (360 degrees) pulsation

c. Machine-washable AutoVest® (HomeCare) simplifies cleaning

d. Soft Start® technology reduces "squeeze effect" and "vest creep" on start up

e. Wheeled AutoVest® Carrier travels easily – fits inside airplane as carry-on

F. What if a patient has a tracheostomy? How does that work with the AutoVest®?

The medical literature reports that HFCWO works equally as well on patients with a tracheostomy and compromised airway clearance; however, such a medical decision should always be left up to the attending physician.

G. How does the AutoVest® enhance patient comfort?

The AutoVest® has patient comfort features such as Soft Start® technology, an offset single-hose, no direct pounding on the sternum or abdomen, and soft, breathable fabri
