ResMed Double Limb Adapter CC — Astral Ventilator

Description

Quick answer: The ResMed Double Limb Adapter CC is an interchangeable circuit adapter for the ResMed Astral ventilator that lets you connect a double limb breathing circuit, with the expiratory valve built into the adapter. Double limb mode is supported on the Astral 150 only. It fits into the device’s adapter socket and is selected based on the circuit type your clinician uses. ResMed reference code: 27980.

What is the Astral double limb adapter used for?

The ResMed Astral supports single and double limb circuits through interchangeable circuit adapters that fit into the back of the device. There are three adapters — single limb leak, single limb (expiratory valve in circuit), and double limb — and the correct adapter must be fitted before the patient circuit is connected. This is the double limb adapter: it is used when the patient is on a double limb circuit, and the expiratory valve is integrated into the adapter itself. Double limb circuits are typically used in higher-acuity or invasive ventilation setups where precise control of inspiratory and expiratory flow is needed.

Key features

• Enables double limb ventilation — connects a double limb circuit to the Astral.
• Integrated expiratory valve — the exhalation valve is built into the adapter.
• Interchangeable fit — slots into the Astral adapter socket; swap adapters to change circuit type.

• Secure, clinical-grade connection — designed for reliable invasive and non-invasive ventilation.

Specifications

Is it compatible with my ventilator?

This adapter is for the ResMed Astral ventilator, and double limb circuits are supported on the Astral 150. After fitting a new adapter or changing the circuit, the Astral requires a “learn circuit” procedure. Always follow your circuit configuration and your clinician’s instructions.

Frequently asked questions

What does the double limb adapter do?
It is the circuit adapter that allows a double limb breathing circuit to connect to the Astral ventilator, with the expiratory valve integrated into the adapter rather than the circuit.

Does it work on the Astral 100 or only the Astral 150?
Double limb circuit operation on the Astral is supported on the Astral 150. Check your device model before ordering.

What is the difference between the single limb and double limb adapter?
The single limb adapters are used with single limb circuits (with intentional leak or with an expiratory valve in the circuit); the double limb adapter is used with a double limb circuit and has the expiratory valve built into the adapter.

Do I need to recalibrate after changing it?
Yes — the Astral requires a “learn circuit” step after the adapter or circuit is changed.

Can I get it delivered in Brooklyn or shipped nationwide?
Yes — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus FedEx shipping throughout the continental U.S.
