Description
Quick answer: This is a genuine ResMed double-limb breathing circuit (smooth bore, 22 mm) with water traps for the Astral ventilator. A breathing circuit is the tubing that carries air between the ventilator and the patient. This is the double-limb configuration in the 22 mm (adult) bore, with a smooth interior and integrated water traps that collect condensation. 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 double-limb circuit, one limb delivers air to the patient and a second limb carries exhaled air back. This circuit has a smooth bore (smooth inner wall) for low resistance, is the 22 mm diameter (typically for adult patients), and includes water traps — small reservoirs that collect condensation (“rainout”) from humidified air so it doesn’t pool in the tubing. Because the Astral requires a “learn circuit” procedure when the circuit type changes, follow the clinical team’s setup instructions.
Key features

- Smooth bore — smooth interior wall for low resistance.
- 22 mm diameter — adult bore size.
- Integrated water traps — collect condensation to keep the circuit clear.
- For the ResMed Astral ventilator — via the appropriate circuit adapter.
- Clinician-directed use — set up per the Astral clinical guide.

Is it right for my setup?
Breathing circuits come in different types, diameters (10, 15, or 22 mm), and configurations (single vs double limb), 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. The Astral requires a “learn circuit” step whenever the circuit type is changed. If you’re unsure whether this 22 mm double-limb smooth-bore circuit with water traps matches your prescription, confirm with your provider before ordering.
Frequently asked questions
What is a double-limb circuit?
It uses two limbs — one to deliver air to the patient and one to carry exhaled air away — as opposed to a single-limb circuit.
What do the water traps do?
They collect condensation from humidified air so it doesn’t pool in the tubing, helping keep the circuit clear and airflow consistent.
Who is the 22 mm size for?
The 22 mm bore is the adult diameter. Your clinical team confirms the correct size.
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 — Stark Medical Supplies offers local pickup and delivery in Brooklyn and across NYC, plus USPS shipping throughout the continental U.S.
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.
