Quick answer: This is the genuine ResMed Remote Alarm II for the Astral ventilator, Americas version (part 27903). It repeats the Astral's alarms at a second location — such as a caregiver's room — so critical alerts can be seen and heard even when the caregiver isn't next to the device. Important: the connecting cable is not included and must be ordered separately. A safety accessory for clinician-directed ventilation monitoring.
What's included
- 1 × ResMed Astral Remote Alarm II unit (Americas, part 27903)
Not included: the connecting cable — required for the alarm to function, and ordered separately.
Ventilator not included.
About this part
When someone depends on a ventilator, the alarms matter as much as the therapy — and a caregiver can't always be in the same room. The Remote Alarm II solves that: placed in another room (or wherever the caregiver is), it repeats the Astral's audible and visual alarms, so an alert isn't missed because of distance or a closed door.
It connects to the Astral by cable and mirrors the device's alarm conditions. This unit does not include that cable — the remote alarm cable is a separate item and is needed for the alarm to work, so order it at the same time if you don't already have one. The Americas version is configured for this region.
Because it's a safety component of a monitoring setup, install, test, and use it exactly as directed by the clinical team — including regularly confirming that alarms actually transmit to the remote unit.
