Philips Respironics 22 mm Passive Circuit with Proximal Pressure Line – 10 Pack

Quick answer: These are Philips Respironics passive breathing circuits, 22 mm bore, each fitted with a proximal pressure line — supplied as a 10-pack (SKU 1132340). In a passive circuit, exhaled gas escapes continuously through a fixed leak port rather than a valve; the proximal pressure line lets the ventilator sense pressure near the patient rather than only at the device, for more accurate delivery and triggering. Single-patient, disposable consumables.

What’s included

• 10 × 22 mm passive circuits with proximal pressure line (SKU 1132340)

Ventilator, exhalation port, and patient interface not included. Confirm compatible ventilator models and whether a leak device is included against your packaging.

About these circuits

Ventilator circuits divide into two broad types. In an active circuit, a valve controlled by the ventilator opens and closes to release exhaled gas. In a passive circuit — this type — exhaled gas escapes continuously through a fixed leak port, and the ventilator compensates for that known leak in its calculations. Passive circuits are simpler, with fewer moving parts, and are widely used in home ventilation.

The proximal pressure line is the thin secondary line running alongside the main tubing. It carries pressure information from near the patient back to the device, so the ventilator reads what’s actually happening at the patient end rather than inferring it from the machine end. That improves the accuracy of pressure delivery and of breath triggering — which matters most when the patient’s own effort is subtle.

The 22 mm bore is the adult size. A 10-pack is the practical fulfilment quantity for clinics, home-care agencies, and anyone changing circuits on a routine schedule.

Key features

• Philips Respironics passive circuits — fixed-leak design, no exhalation valve.
• Proximal pressure line included — pressure sensed near the patient.
• 22 mm bore — adult size.
• 10-pack — economical supply for scheduled changes.
• Single-patient use — hygienic, disposable design.

Specifications

Use & safety notes

Set up the circuit exactly as specified in the ventilator’s clinical documentation, and confirm the proximal pressure line is connected, not kinked, twisted, or occluded — a blocked pressure line gives the device incorrect information and can trigger alarms or affect delivered therapy. A passive circuit requires an appropriate leak/exhalation port in the setup; confirm what your configuration uses. Many ventilators require a circuit test or calibration after a circuit change — run it before returning the patient to therapy. Replace circuits per the manufacturer’s instructions and your clinical protocol.

Frequently asked questions

How many circuits are in the pack?
Ten.

What’s the difference between a passive and an active circuit?
A passive circuit vents exhaled gas continuously through a fixed leak port; an active circuit uses a valve the ventilator opens and closes. This is the passive type.

What does the proximal pressure line do?
It carries pressure information from near the patient back to the ventilator, so pressure delivery and triggering are based on conditions at the patient end.

Which ventilators do these fit?
Please confirm against the packaging, or contact us at (646) 933-0080 with your ventilator model and we’ll check before you order.

Is a leak/exhalation port included?
Confirm against your packaging — configurations vary. Contact us if you’d like us to check.

How often should they be replaced?
Per the manufacturer’s instructions and your clinical protocol, and sooner if soiled, damaged, or if the pressure line is blocked.

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

Can I get them 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.

For use under clinical direction. Follow the manufacturer’s instructions for use, the ventilator’s clinical documentation, and your provider’s or facility’s protocol — including any required circuit test after a circuit change.
