ResMed Universal Disposable Bi-Level Circuit without Filter (72″)

Description

Quick answer: This is the ResMed universal disposable bi-level breathing circuit (part 21953) — a single-use circuit for bilevel/CPAP ventilators, with 72″ (6 ft) tubing, a swivel connector, an exhalation port with cap plug, and a pressure line assembly kit — supplied without an inline filter. A double-cap closure lets clinicians cap off the exhalation port for use with vented or non-vented interfaces. Universal design fits a range of bilevel/CPAP devices. Sold by the case. This version has no filter (a with-filter version, 21952, is also available). Clinician-directed.

What’s included

• Universal disposable bi-level circuits (no filter) — case quantity (each: 72″ tubing, swivel connector, exhalation port + cap plug, pressure line assembly kit)

Inline filter, ventilator, and mask/interface not included.

About this part

A bi-level breathing circuit carries pressurized air from a bilevel (BiPAP) or CPAP ventilator to the patient interface, with an exhalation path for CO₂ washout. This universal, single-use circuit is built for flexibility and hygiene — and this version comes without the inline filter (for setups that filter elsewhere or don’t require an inline circuit filter):

• 72″ (6 ft) tubing — ample length, with a swivel connector for freedom of movement.
• Exhalation port + cap plug (double-cap closure) — lets clinicians cap off the exhalation port so the circuit works with vented interfaces (mask has its own vent) or non-vented interfaces (circuit provides exhalation). This flexibility is what makes it “universal.”
• No inline filter — if you need a filter built into the circuit, choose the 21952 version instead.
• Pressure line assembly kit — a proximal pressure line so the ventilator can monitor pressure at the patient.
• Single-use, disposable — for hygiene and infection control; discard per guidelines.
• Universal fit — designed to work with a range of bilevel/CPAP ventilators.

Filter vs no-filter — get the right one

• 21953 (this) — universal disposable bi-level circuit without filter.
• 21952 — the same universal circuit with an inline filter.

Choose based on whether your setup calls for the inline filter.

Frequently asked questions

What is this circuit for?
It’s a single-use breathing circuit for bilevel/CPAP ventilators — it carries pressurized air to the patient interface with an exhalation path for CO₂ washout.

Does it include a filter?
No — 21953 comes without an inline filter. A version with the filter is available as 21952.

Can I use it with vented and non-vented masks?
Yes — the double-cap closure lets clinicians cap the exhalation port for vented interfaces, or leave it for non-vented setups.

How long is the tubing?
72 inches (6 feet).

Is it reusable?
No — it’s single-use and disposable, for hygiene. Discard per guidelines.

Do I need a prescription?
This is a clinician-directed ventilation component and may require a prescription or facility license. Contact us to confirm.

How is it delivered?
Given the clinical nature of ventilation circuits, please contact us to confirm availability and delivery options.

This is a single-use ventilator breathing circuit. Circuit selection and setup (including vented vs non-vented configuration) are determined by the clinical team. Discard per guidelines. This listing is informational and is not medical advice.
