User/Owner Responsibility The user or owner of this system shall have sole responsibility and liability for any injury to persons or damage to property resulting from: • operation which is not in accordance with the operating instructions supplied • maintenance or modifications carried out unless in accordance with authorized instructions and by authorized persons. Please read this manual carefully before use. This manual contains special terms and icons that appear in the margins to draw your attention to specific and important information. • Warning alerts you to possible injury. • Caution explains special measures for the safe and effective use of the device. • Note is an informative or helpful note.

Medical Information What the VPAP III and VPAP III ST Are Intended For The VPAP III and VPAP III ST systems are intended for the treatment of obstructive sleep apnea (OSA) in adult patients for home and hospital use.

!

CAUTION (USA ONLY) Federal law restricts this device to sale by or on the order of a physician.

Tell Your Doctor If... You must tell your doctor, and CPAP (continuous positive airway pressure) or bilevel therapy must not be used, if you have any of the following conditions: • pneumothorax or pneumomediastinum • severe heart failure, low blood pressure, or dehydration

Introduction

1

surgery to the brain, middle or inner ear, pituitary gland, or sinuses respiratory distress syndrome • middle ear infection or perforated ear drum • severe nosebleed. • •

Warnings CPAP or bilevel therapy should be used with caution if you have any of the following conditions: • respiratory failure • cavities or cysts in the lung, or previous history of pneumothorax • previous history of severe nosebleed • sinus infection. Tell your doctor if you have any of these conditions. Your doctor will advise you whether the likely benefits of CPAP or bilevel therapy outweigh the expected risks. Special care should be exercised if you are dehydrated, or may become dehydrated, for example as a result of fluid restriction or diuretic therapy (including changes in therapy). Discontinue therapy and seek medical advice if, during therapy or when you start therapy each night, you feel faint or light-headed. The following are general warnings that pertain to your use of a VPAP unit. Specific warnings appear next to the relevant instructions in the manual.

!

WARNING This is NOT a life support device. It may stop operating with power failure or if a fault occurs in the unit. • The air flow for breathing produced by this device can be as much as 11°F (6°C) higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 90°F (32°C). • The VPAP unit should only be used with masks (and connectors)* recommended by ResMed, or by your physician or respiratory therapist. A mask should not be used unless the VPAP unit is turned on and operating properly. The vent hole or holes associated with the mask should never be blocked. Explanation: The VPAP unit is intended to be used with special masks (or connectors)* which have vent holes to allow continuous flow of air out of the mask. When the device is turned on and functioning properly, new air from the device flushes the exhaled air out through the mask vent holes. However, when the device is not operating, insufficient fresh air will be provided through the mask, and the exhaled air may be •

• • •

rebreathed. Rebreathing of exhaled air for longer than several minutes can, in some circumstances, lead to suffocation. This applies to most models of CPAP or bilevel devices. The VPAP unit should only be connected to the components, humidifiers, or accessories specified in this manual. Connection of other items may result in injury, or damage to the VPAP unit. At low pressures, the flow through the exhalation ports of your mask may not clear all exhaled gas from the tubing. Some rebreathing may occur. Explosion hazard-do not use in the vicinity of flammable anesthetics. If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating. Explanation of the warning: When the device is not in operation and the oxygen flow is left on, oxygen delivered into the ventilator tubing may accumulate within the device enclosure. Oxygen accumulated in the device enclosure will create a risk of fire. This warning applies to most types of flow generators. Oxygen supports combustion. Oxygen should not be used while smoking or in the presence of an open flame. Always ensure air flow is being generated by the device before the oxygen supply is turned on. Always turn the oxygen supply off before stopping the air flow from the device.

Note: At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary, depending on where the oxygen is introduced, pressure settings, patient breathing pattern, mask selection, and leak rate. This applies to most types of flow generators.

Warnings related to treatment

!

WARNING If you stop your CPAP or bilevel treatment, your sleep apnea will return immediately. • Always consult your clinician if you expect to be in a situation where you cannot use your VPAP unit. • If you are admitted to a hospital or prescribed any other form of medical treatment, always inform the medical staff that you are being treated with CPAP or bilevel. It is also important to contact the clinician who is treating you for sleep apnea. • If you experience an infection of the upper respiratory tract, middle ear, or sinuses, contact your clinician before continuing your CPAP or bilevel treatment. You may be advised to stop treatment until the infection has cleared. If you continue with treatment during an infection, be sure to clean your mask and tubing after every use. •
