Life support ventilators

Astral provides mobile non-invasive and invasive ventilation to support daily living for less-dependent to fully dependent patients (>5kg)* in need of acute and/or long-term care. Astral features a variety of modes, circuits and interfaces to treat a wide range of conditions.

Powered for everyday life

Weighing just 3.2 kg with long-lasting batteries** and practical accessories, Astral is made for living life. With Astral, you can feel confident you’re receiving ventilation that suits your respiratory needs as prescribed by your doctor. A mobility bag can protect Astral when you’re on the move: the Astral mobility bag has room for all of Astral’s essential accessories, while the lighter but smaller SlimFit mobility bag has a pouch for the power supply or external battery. Transparent panels mean you can easily access the touchscreen.


Secure by design

Astral’s sophisticated technologies and advanced alarms simplify life for you and your caregivers. Astral features fixed and adjustable alarms, including an advanced disconnection alarm designed for added reassurance and the optional Remote Alarm II so you can stay connected to remote or hospital alarm systems. A big-button feature on the main display allows you to start or stop the ventilator, or mute the alarm, simply by touching the screen.

Astral’s large colour display means your clinicians and carers can easily access essential information about your condition.

Versatile, practical, liveable

When it comes to life support ventilation, everyone’s needs are different. Astral provides ventilation during the day and at night whether you are tracheotomised or non-invasively ventilated with a mask or mouthpiece. Astral makes it easy to manage complexity. There’s no need to change the circuit when you switch from a mask to a mouthpiece. Because your breathing needs may change throughout the day, Astral can save multiple programmes and settings. At the press of a button, you can switch to the pre-set programme that’s most suitable for you at the time.
