AutoSet™ CS-A
ADAPTIVE SERVO-VENTILATOR
Information Guide
English
Please read the entire Information and Welcome Guides before using your device.
Indications for use
The AutoSet CS-A is indicated to stabilise the ventilation of adult patients exhibiting central sleep
apnoea (CSA), mixed sleep apnoea and periodic breathing, with or without obstructive sleep apnoea.
It is intended for home and hospital use.
Contraindications
ASV therapy is contraindicated in patients with chronic, symptomatic heart failure (NYHA 2-4) with
reduced left ventricular ejection fraction (LVEF ≤ 45%) and moderate to severe predominant central
sleep apnoea.
Positive airway pressure therapy may be contraindicated in some patients with the following preexisting conditions:
• severe bullous lung disease
• pneumothorax or pneumomediastinum
• pathologically low blood pressure, particularly if associated with intravascular volume depletion
• dehydration
• cerebrospinal fluid leak, recent cranial surgery, or trauma.
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 device:
• drying of the nose, mouth, or throat
• nosebleed
• bloating
• ear or sinus discomfort

WARNINGS
• Read the entire manual before using the device.
• Use the device only as directed by your physician or healthcare provider.
• Use the device only for the intended use as described in this manual. Advice contained in this
manual should not supersede instructions given by the prescribing physician.
• If you notice any unexplained changes in the performance of the device, if it is making unusual
or harsh sounds, if the device or the power supply are dropped or mishandled, if water is spilled
into the enclosure, or if the enclosure is broken, discontinue use and contact your ResMed
Service Center.
• Beware of electrocution. Do not immerse the device, humidifier, power supply or power cord in
water. In the event of a spill, disconnect the device from the power supply and let the parts dry.
Always unplug the device before cleaning and make sure that all parts are dry before plugging in
the device.
• Explosion hazard—do not use in the vicinity of flammable anesthetics.
• Make sure the power cord and plug are in good condition and the equipment is not damaged.
• Keep the power cord away from hot surfaces.
• The device should only be used with masks (and connectors
1
) recommended by ResMed, or by
a physician or respiratory therapist. A mask should not be used unless the device is turned on.
Once the mask is fitted, ensure that the device is blowing air. The vent hole or holes associated
with the mask should never be blocked.
1
Ports may be incorporated into the mask or in connectors that are near the mask.
English 15
Explanation: The device 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.
• Oxygen supports combustion. Oxygen must not be used while smoking or in the presence of an
open flame.
• Always ensure that the device is turned on and airflow generated before the oxygen supply is
turned on. Always turn the oxygen supply off before the device is turned off, so that unused
oxygen does not accumulate within the device enclosure and create a risk of fire.
• Do not leave long lengths of air tubing around the top of your bed. It could twist around your
head or neck while you are sleeping.
• Do not use electrically conductive or antistatic air tubings.
• Do not use the air tubing if there are any visible signs of damage.
• Only ResMed air tubing and accessories should be used with the device. A different type of air
tubing or accessory may alter the pressure you actually receive, reducing the effectiveness of
the treatment.
• Only use the ResMed 90W or 30W power supply unit. Use the 90W power supply unit to power
the system comprising the device, H5i, air tubing, DC/DC converter and battery pack. The 30W
power supply unit is designed to power the device only and recommended for travelling.
• Only ResMed products are designed to be connected to the module connector port. Connecting
other devices could damage the device.
• Blocking the air tubing and/or air inlet of the device while in operation could lead to overheating
of the device.
CAUTIONS
• Do not open the device enclosure. There are no user serviceable parts inside. Repairs and
servicing should only be performed by an authorised ResMed service agent.
• Do not use bleach, chlorine, alcohol, or aromatic-based solutions, moisturizing or antibacterial
soaps or scented oils to clean the device, humidifier or air tubing. These solutions may cause
damage and reduce the life of these products.
16
• Incorrect system setup may result in incorrect mask pressure reading. Ensure the system is
correctly set up.
• Be careful not to place the device where it can be bumped or where someone is likely to trip
over the power cord.
• Make sure that the area around the device is dry and clean and clear of bedding, clothes or other
objects that could block the air inlet or cover the power supply unit.
• Ensure that the device is protected against water if used outdoors. Enclose the device in the S9
travel bag for transport.
