Introduction
The Astral device provides mechanical ventilation to both ventilation dependent and non-dependent
patients. It delivers pressure and volume ventilation through either a valve or leak circuit, and is
compatible with a range of accessories to support specific use cases.
The information in this guide applies to both the Astral 100 and the Astral 150 devices. Where
information applies to only one of these devices, that device will be specified.
Note: Some features may not be available on your device.
WARNING
•
Read the entire manual before using the Astral device.
•Use the Astral device only as directed by a physician or healthcare provider.
•Use the Astral device only for the intended use as described in this manual. Advice contained
in this manual does not supersede instructions given by the prescribing physician.
•Install and configure the Astral device in accordance with the instructions provided in this
guide.
Indications for use
The Astral 100/150 provides continuous or intermittent ventilatory support for patients weighing more
than 5 kg who require mechanical ventilation. The Astral device is intended to be used in home,
institution/hospital and portable applications for both invasive and non-invasive ventilation.
CAUTION
The Astral device is not intended for use as an emergency transport ventilator.
Contraindications
The Astral device is contraindicated in patients with the following pre-existing conditions:
•pneumothorax or pneumomediastinum
•pathologically low blood pressure, particularly if associated with intravascular volume depletion
•cerebrospinal fluid leak, recent cranial surgery or trauma
•severe bullous lung disease
•dehydration.
WARNING
AutoEPAP is contraindicated when using an invasive interface.
Adverse effects
Report unusual chest pain, severe headache or increased breathlessness to your physician. The following
side effects may arise during use of the device:
•drying of the nose, mouth or throat
•nosebleed
•bloating
•ear or sinus discomfort
•eye irritations
•skin rashes.

Introduction

General warnings and cautions
The following are general warnings and cautions. Further specific warnings, cautions and notes appear
next to the relevant instruction in the manual.
A warning alerts you to possible injury.
WARNING
•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 discontinue use
and contact your healthcare provider.
•For ventilator-dependent patients, always have alternate ventilation equipment available, such
as a back-up ventilator, manual resuscitator or similar device. Failure to do so may result in
patient injury or death.
•The Astral device is a restricted medical device intended for use by qualified, trained personnel
under the direction of a physician. Clinical supervision is required in critical care/intensive care
unit environments.
•Ventilator-dependent patients should be continuously monitored by qualified personnel or
adequately trained carers. These personnel and carers must be capable of taking the necessary
corrective action in the event of a ventilator alarm or malfunction.
•The internal battery is not intended to serve as a primary power source. It should only be used
when other sources are not available or briefly when necessary; for example, when changing
power sources.
•The Astral device is not intended to be operated by persons (including children) with reduced
physical, sensory or mental capabilities without adequate supervision by a person responsible
for the patient's safety.
•The Astral device is not intended to be operated by patients unless they have been given
adequate instruction concerning the operation of the device by a person responsible for the
patient's safety.
•The Astral device must not be used in the vicinity of an MRI or diathermy device.
•The effectiveness of ventilation and alarms should be verified including after any ventilation or
alarm setting change, any change in circuit configuration, or after a change to co-therapy (eg,
nebulisation, oxygen flow).
•The Astral device and AC Power Supply can get hot during operation. To prevent possible skin
damage do not leave the Astral device or AC Power Supply in direct contact with the patient for
extended periods of time.
•The device can provide therapies typically associated with both ventilator-dependent and
non-dependent patients. The mode of ventilation, circuit type, and alarm strategies should be
chosen after a clinical evaluation of each patient’s needs.
•The device must not be used at an altitude above 3000m or outside the temperature range of
0–40°C. Using the device outside these conditions can affect device performance which can
result in patient injury or death.

Introduction
English 3
A caution explains special measures for the safe and effective use of the device.
CAUTION
•Repairs and servicing of the device should only be performed by an authorised ResMed service
representative.
•The temperature of the airflow for breathing produced by the device can be as much as 6ºC
higher than the temperature of the room. Caution should be exercised if the room temperature
is warmer than 35ºC.
•Do not expose the device to excessive force, dropping or shaking.
•Dusty environments may affect device performance.
•The Astral device may experience interference in the vicinity of electronic article surveillance
(EAS). Keep the Astral device at least 20 cm away from the EAS.
A note advises of special product features.
Notes:
•When using Astral for long term invasive ventilation in the home, due consideration should be given to relevant
practice guidelines such as the AARC Clinical Practice Guideline for Long Term Invasive Mechanical Ventilation
in the Home - 2007 Revision & Update (www.rcjournal.com/cpgs/pdf/08.07.1056.pdf)
•For assistance and reporting of issues associated with the Astral device, contact your Health Care Provider or
authorised ResMed representative.

For information on attaching and using patient circuit accessories, refer to Attaching patient circuit
accessories (see page 48).
Power accessories
WARNING
•
The Astral device should only be used with accessories recommended by ResMed. Connection
of other accessories could result in patient injury or damage to the device.
•Connecting the Astral device to the battery of a battery-powered wheelchair may affect the
device performance and may result in patient harm.
The Astral device can be connected to a range of accessories as follows:
•Astral External Battery
•ResMed Power Station II
•Astral DC adapter
•ResMed Remote Alarm II
•Pulse Oximeter.

Power accessories
12
Power supplies
In addition to the internal battery and mains power sources, the Astral device can be powered from the
following sources:
•Astral External Battery
•ResMed Power Station II
•Astral DC adapter.
Astral External Battery
The Astral External Battery has been designed specifically for use with the Astral series of ventilators. It
is intended to provide Astral ventilators with eight hours of power when mains power is unavailable
during typical use.
ResMed Power Station II (RPSII)
The RPSII is an external lithium-ion battery that provides power when mains power is unavailable.
Remote Alarm II
The Remote Alarm II is self-powered (via battery) and connected to the Astral device via a cable. If
required, a second Remote Alarm can be attached to the first Remote Alarm. This enables Remote
Alarms to be placed in two separate locations. The Remote Alarm II can also be connected to a hospital
alarm management system. For more information, see the Remote Alarm II user guide.
Pulse oximeter
Attaching a pulse oximeter to the Astral device enables real-time SpO2and pulse readings to be viewed
from the Monitoring menu. For further information, refer to Attaching a pulse oximeter (see page 54).
