ResMed Astral Double Limb Coaxial Circuit – 30 mm

Description

Quick answer: This is a double limb coaxial breathing circuit (30 mm outer diameter, 1.6 m) for the ResMed Astral ventilator. The coaxial “tube-within-a-tube” design combines both the inspiratory and expiratory limbs into a single compact tube, reducing bulk and clutter compared with two separate limbs while still delivering full double limb ventilation. Adult, single-patient use. ResMed reference code: 21323.

What is a coaxial circuit?

A breathing circuit carries air between the ventilator and the patient. A double limb circuit has separate inspiratory (to the patient) and expiratory (away from the patient) paths. In a coaxial circuit, one limb runs inside the other within a single outer tube, so instead of two parallel hoses you have one neat 30 mm tube. This makes the circuit easier to manage and less prone to tangling, while keeping the benefits of double limb ventilation. The Astral supports single and double limb circuits through interchangeable circuit adapters, so a coaxial circuit is used with the appropriate double limb adapter fitted to the device.

Key features

• Coaxial (tube-within-a-tube) design — both limbs combined into one 30 mm tube.
• Less bulk and tangling — neater than two separate limbs.
• Full double limb ventilation — separate inspiratory and expiratory flow paths.
• 1.6 m length — practical reach for most setups.
• Adult, single-patient use — supports hygiene and infection control.

Specifications

Is it compatible with my ventilator?

This circuit is designed for the ResMed Astral ventilator and is used with the double limb circuit adapter fitted to the device. After assembling or changing a circuit, the Astral requires a “learn circuit” procedure. Always follow your circuit configuration and your clinician’s instructions.

Frequently asked questions

What is a coaxial breathing circuit?
It’s a double limb circuit where one limb runs inside the other within a single outer tube, so you get separate inspiratory and expiratory paths in one compact 30 mm hose instead of two.

What’s the difference between a coaxial and a standard double limb circuit?
A standard double limb circuit uses two separate tubes; the coaxial version combines them into one, which reduces bulk and tangling. Both provide double limb ventilation. Your clinician will advise which is appropriate.

Is it single-patient use?
Yes — it is intended for single-patient use to support hygiene and infection control.

Do I need a prescription?
Ventilator circuits are supplied as part of clinician-directed respiratory care. Use this product as directed by your healthcare provider.

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.
