Quick answer: This is the genuine ResMed MPV circuit support arm (part 27955) — a support arm designed specifically for mouthpiece ventilation (MPV). It holds the mouthpiece and circuit in a stable, accessible position so the patient can reach it to take breaths on demand, while keeping the tubing routed and out of the way. Used with the ResMed Astral ventilator for mouthpiece (open-circuit) ventilation. It is a different, MPV-specific arm from the general premium circuit support arm (24917). Ventilator and circuit not included.
What’s included
- 1 × ResMed MPV circuit support arm (part 27955)
Ventilator, mouthpiece, and circuit not included.
About this part
Mouthpiece ventilation (MPV) is an open-circuit form of non-invasive ventilation where the patient takes assisted breaths from a mouthpiece on demand — often used during the day, for example by neuromuscular patients, alongside or instead of a mask. Positioning the mouthpiece so the patient can easily reach it is essential, and that’s what this arm does:
- Positions the mouthpiece — holds the mouthpiece and circuit in a stable spot within easy reach (e.g. mounted near a wheelchair or bed), so the patient can lean in and take a breath when needed.
- MPV-specific design — shaped and adjusted for mouthpiece ventilation setups.
- Keeps the circuit tidy — routes the tubing and holds its position during therapy.
- Adjustable — position and angle to suit the patient’s reach and posture.
Important — MPV arm (27955) vs premium circuit support arm (24917)
These are two different support arms — order the right one:
- 27955 (this) — the MPV circuit support arm, designed specifically for mouthpiece ventilation setups.
- 24917 — the premium circuit support arm, a general-purpose arm for holding single- or double-limb circuits/mouthpieces (Stellar/Astral/Lumis/S9), which uses tube clips (24919/24920) and mounts to a trolley/stand.
Match the arm to your setup and clinical configuration.
