INTRODUCTION Thank you for choosing the S8 LIGHTWEIGHT™ flow generator. The S8 LIGHTWEIGHT is a compact, all-in-one package with an inbuilt power supply and the option of integrated data management and humidification. This user manual contains the information you need for the correct use of your S8 LIGHTWEIGHT.
INTRODUCTION
338239r1.book Page 1 Tuesday, July 5, 2005 1:58 PM
YOUR RESPONSIBILITY The owner or user 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 authorised instructions and by authorised 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 ABOUT THE S8 LIGHTWEIGHT™ The S8 LIGHTWEIGHT continuous positive airway pressure (CPAP) system is indicated for the treatment of obstructive sleep apnoea (OSA) in adult patients. The S8 LIGHTWEIGHT CPAP system is intended for home and hospital use.
CONTRAINDICATIONS The S8 LIGHTWEIGHT is not a life support device and may stop operating during power failure or certain fault conditions. It should not be used by patients who are dependent on continuous therapy. Positive airway pressure therapy may be contraindicated in some patients with the following pre-existing conditions: • severe bullous lung disease • pneumothorax • pathologically low blood pressure • dehydration • cerebrospinal fluid leak, recent cranial surgery, or trauma.

338239r1.book Page 2 Tuesday, July 5, 2005 1:58 PM
WARNINGS Read the entire manual before using the S8 LIGHTWEIGHT. Advice contained in this manual should not supersede instructions given by the prescribing physician. • A patient should not connect a device to the data communication port unless instructed to do so by their health care provider or physician. Only ResMed products are designed to be connected to the data communication port. Connecting other devices could result in injury, or damage to the S8 LIGHTWEIGHT device. • The S8 LIGHTWEIGHT should only be used with masks (and connectors)* recommended by ResMed, or by a physician or respiratory therapist. A mask should not be used unless the S8 LIGHTWEIGHT device is turned on and operating properly. The vent hole or holes associated with the mask should never be blocked. Explanation: The S8 LIGHTWEIGHT 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 devices. • •
In the event of power failure or machine malfunction, remove the mask. The S8 LIGHTWEIGHT can be set to deliver pressures up to 20 cm H2O. In the unlikely event of certain fault conditions, pressures up to 30 cm H2O are possible. • If oxygen is used with this device, the oxygen flow must be turned off when the device is not operating. If oxygen has been left on, turn off the flow generator, then wait 30 minutes before turning on the flow generatory again. Explanation: When the CPAP device is not in operation and the oxygen flow is left on, oxygen delivered into the air delivery tubing may accumulate within the CPAP machine enclosure and create a risk of fire. This applies to most types of CPAP machines. • Oxygen supports combustion. Oxygen should not be used while you are smoking or in the presence of an open flame. • Always ensure airflow is being generated by the device before the oxygen supply is turned on. • Always turn the oxygen supply off before stopping the airflow 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, the pressure settings, patient breathing pattern, mask selection and leak rate. • •
*
2
Ports may be incorporated into the mask or in connectors that are near the mask.
Do not use the S8 LIGHTWEIGHT if there are obvious external defects or unexplained changes in performance. • Do not open the S8 LIGHTWEIGHT case. There are no user serviceable parts inside. Repairs and internal servicing should only be performed by an authorised service agent. • Explosion hazard-do not use in the vicinity of flammable anaesthetics. •
CAUTIONS
MEDICAL INFORMATION
338239r1.book Page 3 Tuesday, July 5, 2005 1:58 PM
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. • The airflow for breathing produced by this device can be as much as 6°C higher than the temperature of the room. Caution should be exercised if the room temperature is warmer than 32°C. • When AC mains power (100–240V AC) is not available, always use a ResMed DC-12 converter. (The DC-12 converter is available as an optional accessory. It is not supplied with all models.) • If supplied, the Data Card module is designed for use with specific ResMed devices. • Only use the Data Card module (if supplied) as specified in this manual. Note: The above are general warnings and cautions. Specific warnings, cautions and notes appear with the relevant instructions in the manual. •
ADVERSE EFFECTS Patients should report unusual chest pain, severe headache or increased breathlessness to their prescribing physician. An acute upper respiratory tract infection may require temporary discontinuation of treatment. The following side effects may arise during the course of therapy with the CPAP device: • drying of the nose, mouth or throat • nosebleed • bloating • ear or sinus discomfort • eye irritation • skin rashes • chest discomfort.
