ResMed Astral Ventilators 100/150
The ResMed Astral 100 and Astral 150 are portable life-support ventilators designed for both invasive and non-invasive ventilation. In the U.S., they are indicated for patients over 11 lb (5 kg) who require continuous or intermittent mechanical ventilation, and they can be used in the home, hospital/institutional setting, and portable applications.
Key Highlights
- Invasive and non-invasive ventilation via mask, mouthpiece or tracheostomy
- Pressure and volume ventilation modes
- iVAPS™ with Intelligent Backup Rate and optional AutoEPAP
- Advanced leak compensation
- Approximately 7 lb with 8 hours internal battery
- Multiple configurable programs for changing patient needs

Key clinical and therapy features
Invasive and non-invasive ventilation — Supports mask, mouthpiece, and tracheostomy applications.
Pressure and volume ventilation — Provides flexibility for patients with different respiratory requirements.
iVAPS™ (intelligent Volume-Assured Pressure Support) — Automatically adjusts pressure support to maintain a targeted level of alveolar ventilation.
Intelligent Backup Rate (iBR) — Works with iVAPS to encourage spontaneous breathing while providing backup support when needed.
AutoEPAP option with iVAPS — Automatically adjusts EPAP to help maintain upper-airway patency. AutoEPAP is for non-invasive use and is contraindicated with an invasive interface.
Advanced leak compensation — Designed to maintain effective ventilation and patient-device synchrony despite changing leaks.
Adjustable trigger and cycle sensitivity — Helps clinicians tailor synchronization to an individual patient's respiratory effort.
Multiple configurable programs — Allows different ventilation programs to be established for changing patient needs throughout the day.
Portability and battery life
Portability is one of Astral's strongest differentiators. The ventilator weighs approximately 7 lb (3.2 kg) and incorporates an internal battery providing approximately 8 hours of operation under typical conditions. Optional external batteries can provide additional portable power; ResMed states that two external batteries can provide up to 16 hours of continuous portable power, with the internal battery providing additional backup.
