Quick answer: The ResMed Astral Catheter Mount (smooth bore with port, 22F) is a flexible single-limb connector that links a patient's tracheostomy or endotracheal tube to the Astral ventilator breathing circuit. Its smooth internal bore minimizes airflow resistance, the integrated port allows suctioning or monitoring without disconnecting the circuit, and the 22F (22 mm female) fitting matches the standard Astral circuit connection. ResMed reference code:
21341.
What is the Astral catheter mount used for?
A catheter mount (also called a flexible connector or "swivel" connector) sits between the patient's airway interface and the main ventilator circuit. It gives the circuit flexibility so head and body movement does not pull or torque on the tracheostomy or ET tube, which improves patient comfort and reduces the risk of accidental dislodgement. The built-in capped
port provides access for suction catheters or monitoring lines, so caregivers can perform suctioning without breaking the circuit and interrupting ventilation.
Key features
- Smooth bore design — low-resistance internal lumen for optimal, stable airflow.
- Integrated access port — suction or monitoring access without disconnecting the patient.
- 22F connection (22 mm female) — standard fitting for ResMed Astral patient circuits.
- Flexible construction — reduces strain on the airway during patient movement.
- Single-patient use — designed for hygienic, single-patient application.

Is it compatible with my ventilator?
This catheter mount is designed for the
ResMed Astral ventilator family and connects to standard 22 mm Astral circuits. The Astral supports single and double limb circuits using interchangeable circuit adapters, and after assembling or changing a circuit the device requires a "learn circuit" procedure. Always follow your circuit configuration and your clinician's instructions.
Frequently asked questions
What does "smooth bore with port" mean? "Smooth bore" means the inside of the tube is smooth rather than corrugated, which lowers airflow resistance. "With port" means it includes a capped access point for suctioning or monitoring without disconnecting the patient from the ventilator.
What is the difference between the smooth bore and corrugated catheter mount? Both connect the patient to the Astral circuit. The smooth bore version (code 21341) offers lower flow resistance; the corrugated version (code 21342) is also available for the Astral. Your respiratory therapist can advise which is appropriate.
Is this a single-patient-use item? Yes. Catheter mounts are intended for single-patient use for hygiene and infection control.
Do I need a prescription? Ventilator accessories are typically 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 — Task Supply Corp offers FedEx shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
This product is a medical device accessory. Use it according to the ResMed Astral user guide and the directions of your healthcare provider.
