Secure by design

Astral’s systems have been thoughtfully designed so, whatever setup is chosen, caregivers can feel confident that each transition will be smooth and effective.

A disconnection alarm can be titrated to a wide range of setups. Even small changes, like disconnection of a small diameter tracheotomy tube, will trigger the alarm. For confident adjustment, the Learn Circuit automatically measures the circuit resistance and compliance of the breathing circuit components, then adapts and compensates accordingly.

Versatile, practical, liveable

Astral delivers a suite of therapy modes in a broad range of scenarios. It can be used during the day and at night, for tracheotomised patients or non-invasively ventilated patients with a mask or mouthpiece. This versatility enables you to cater for a wide variety of patients, from adults to children weighing as little as 5kg.

Astral makes it easy to manage complexity. There’s no need to change the circuit when you switch from a mask to a mouthpiece. You can choose from a range of trigger options to match your patient’s inspiratory effort. It’s easy to flex between different circuit configurations and settings and to keep track of them, with four configurable programmes and the option to name them.

Work fast and efficiently

From initial setup to ongoing care, Astral is designed to provide the best user experience possible. Its intuitive interface gives you the tools and information you need to make fast and early decisions.

ResMed worked closely with clinical experts to make Astral easy to use and understand. The intuitive interface provides breath-by-breath statistics and auto-scaling real-time pressure and flow waveforms. Device and battery management is simplified by maintenance reminders and fast USB cloning of settings between devices.

The expert’s voice

“We tried to see the results and if patient comfort was improved. And the trials were pretty positive.”

“Due to this tidal volume computation, the leak configuration is also much more flexible and much more powerful in terms of leak compensation”
