NOTES:

The Vest® Airway Clearance System, Model 105 1
Instructions for Use(145330 REV 18)
Intended Use
INTENDED USE
The Vest® Airway Clearance System, Model 105 was developed to provide
effective Airway Clearance Therapy. The system consists of an inflatable
garment attached to an Air Pulse Generator that rapidly inflates and
deflates the inflatable garment. This causes the chest wall to be gently
compressed and released, which creates airflow within the lungs. This
process moves the mucus toward the large airways where it can be
cleared by coughing or suctioning. This type of Airway Clearance Therapy
is referred to as High Frequency Chest Wall Oscillation (HFCWO).
INTENDED PATIENT POPULATION
The Vest® Airway Clearance System, Model 105 can be used for the
pediatric to geriatric population. The system accommodates use across
the targeted population by providing a selection of garment sizes which is
used along with the air pulse generator.
INTENDED USERS
The users of the system can either be designated caregivers or patients in
both the acute care and home care environments. Users should have the
ability to read and understand western Arabic numerals and the native
language used in the manual. We recommend that the users of the device
have an education level comparable to that of an 8th grader. We
recommend that patients who do not meet this education level get
assistance from caregivers or respiratory therapists while using this device
for therapy.

Instructions for Use (145330 REV 18)
Introduction
INDICATIONS FOR USE
The Vest® Airway Clearance System is intended to provide airway
clearance therapy when external manipulation of the thorax is the
physician’s choice of treatment. Indications for this form of therapy are
described by the American Association of Respiratory Care (AARC) in the
Clinical Practices Guidelines for Postural Drainage Therapy. According to
AARC guidelines, specific indications for external manipulation of the
thorax include evidence or a suggestion of retained secretions, evidence
that the patient is having difficulty with the secretion clearance, or
presence of atelectasis caused by mucus plugging. In addition, The Vest®
Airway Clearance System is also indicated for external manipulation of the
thorax to promote airway clearance or improve bronchial drainage for the
purposes of collecting mucus for diagnostic evaluation.
INTRODUCTION
This manual includes instructions for setup, use, and maintenance of The
Vest® Airway Clearance System, Model 105. It is to be used as a reference
guide. Please review all the sections carefully before you use the system.
The Vest® Airway Clearance System, Model 105 is intended for use as
prescribed by a physician.
