About this product

Quick answer: This is a genuine ResMed single-limb breathing circuit (corrugated, 15 mm) for the Astral ventilator. A breathing circuit is the tubing that carries air between the ventilator and the patient. This is the single-limb configuration in the 15 mm bore, with a corrugated (flexible, expandable) wall. The 15 mm corrugated circuit is intended for paediatric patients. Set up and use as directed by the patient's clinical team.

About this circuit

Breathing (ventilator) circuits connect the Astral ventilator to the patient interface. The Astral supports single- and double-limb circuits using interchangeable circuit adapters. In a single-limb circuit, one tube carries air to the patient (with exhalation managed by a valve or vent in the setup). This circuit has a corrugated wall — flexible and expandable, so it bends easily and adjusts to positioning — and is the 15 mm diameter. Per ResMed, the 15 mm corrugated circuit is suitable for paediatric patients only. Because the Astral requires a "learn circuit" procedure when the circuit type changes, follow the clinical team's setup instructions.

Is it right for my setup?

Breathing circuits come in different types, diameters (10, 15, or 22 mm), and configurations (single vs double limb), corrugated or smooth bore, with or without water traps. The right circuit depends on the patient and the prescribed ventilation setup — your clinical team will advise which circuit to use and how to assemble it. This 15 mm corrugated single-limb circuit is intended for paediatric patients. The Astral requires a "learn circuit" step whenever the circuit type is changed. If you're unsure whether this circuit matches your prescription, confirm with your provider before ordering.

Frequently asked questions

What is a single-limb circuit? It uses one tube to carry air to the patient, with exhalation managed by a valve or vent in the setup — as opposed to a double-limb circuit with a separate expiratory limb.

What does "corrugated" mean? The tubing wall is ribbed and flexible (rather than smooth), so it bends easily and can expand — helpful for positioning.

Who is the 15 mm size for? Per ResMed, the 15 mm corrugated circuit is for paediatric patients only. Your clinical team confirms the correct circuit.

Which ventilator does it fit? The ResMed Astral, using the appropriate circuit adapter.

Do I need a prescription? Yes — ventilator circuits are used under clinical direction. Confirm your prescribed setup with your provider.

Can I get it delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.

This is a prescription medical device accessory for use under clinical direction. Follow the Astral clinical/user guide and your healthcare team's instructions, including the required "learn circuit" procedure.
