S/T Patient Guide

Intended Use/Indications for Use

The BiPAP Harmony S/T is a non-invasive, pressure
support ventilator used to augment the breathing of
patients suffering from acute or chronic respiratory
insufficiency, or to maintain airway patency and provide
ventilatory support to patients who experience obstructive
sleep apnea.

It is not intended to provide the total ventilatory
requirements of the patient.

The Harmony S/T is intended for use in the home,
hospital, or other institutional settings.

Contraindications

The Harmony S/T ventilator should not be used if you
have severe respiratory failure without a spontaneous
respiratory drive.

If any of the following conditions apply to you, consult
your physician before using the Harmony S/T ventilator.
Consult your physician if you have:

• the inability to maintain a patent airway or adequately
clear secretions.

• a risk of aspiration of gastric contents.

• acute sinusitis or otitis media.

• an allergy or hypersensitivity to the mask materials
where the risk

from allergic reaction outweighs the benefit of ventila­tory assistance.

• epistaxis.

• hypotension.

The following are potential side effects of noninvasive
positive pressure therapy:

• Ear discomfort

• Conjunctivitis

• Skin abrasions due to noninvasive interfaces

• Aerophagia (gastric distention)

2 Introduction to the Harmony S/T

What is Bi-Level Ventilation?

Bi-level ventilation with the Harmony S/T Ventilatory
Support System helps you to breathe by supplying two
levels of air pressure. The Harmony S/T provides a higher
pressure—known as IPAP (Inspiratory Positive Airway
Pressure)—when you inhale, and a lower pressure—
known as EPAP (Expiratory Positive Airway Pressure)—
when you exhale. The higher pressure opens your airway
to increase the amount of air going into your lungs, and the
lower pressure makes it easier for you to exhale while still
keeping your airway open.

NOTE:Occasionally, cosmetic changes may be made to

the product that do not affect the performance or
specifications of the product. These kinds of
changes do not warrant a reprinting of this
manual. Illustrations are for reference only.

What is the Harmony S/T?

Introduction

The Harmony ventilator, shown in Figure 2-2, supplies
two levels of air pressure through a breathing circuit. The
circuit consists of:

• circuit tubing to deliver the air from the ventilator to
your interface (e.g., mask)

• an exhalation port to vent exhaled air from the circuit

• a mask or other interface to deliver the ventilation to
your nose or nose and mouth, depending on which
interface has been prescribed for you

The system senses your breathing effort and changes
pressure levels when you inhale and exhale.
