Intended Use/Indications for Use

The BiPAP Harmony S/T is a non-invasive, pressuresupport ventilator used to augment the breathing ofpatients suffering from acute or chronic respiratoryinsufficiency, or to maintain airway patency and provideventilatory support to patients who experience obstructivesleep apnea.

It is not intended to provide the total ventilatoryrequirements 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 youhave severe respiratory failure without a spontaneousrespiratory drive.

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

• the inability to maintain a patent airway or adequatelyclear secretions.

• a risk of aspiration of gastric contents.

• acute sinusitis or otitis media.

• an allergy or hypersensitivity to the mask materialswhere the risk

from allergic reaction outweighs the benefit of ventila-tory assistance.

• epistaxis.

• hypotension.

The following are potential side effects of noninvasivepositive 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 VentilatorySupport System helps you to breathe by supplying twolevels of air pressure. The Harmony S/T provides a higherpressure—known as IPAP (Inspiratory Positive AirwayPressure)—when you inhale, and a lower pressure—known as EPAP (Expiratory Positive Airway Pressure)—when you exhale. The higher pressure opens your airwayto increase the amount of air going into your lungs, and thelower pressure makes it easier for you to exhale while stillkeeping your airway open.

NOTE: Occasionally, cosmetic changes may be made tothe product that do not affect the performance orspecifications of the product. These kinds ofchanges do not warrant a reprinting of thismanual. Illustrations are for reference only.

S/T Patient Guide

What is the Harmony S/T?

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

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

• an exhalation port to vent exhaled air from the circuit

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

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