Quick answer: This is a Tri-Pack (3 units) of the ResMed AirCurve 11 ST-A (part 51203) — the most advanced device in the AirCurve 11 bilevel series, a noninvasive ventilator (NIV) for non-dependent patients with complex respiratory needs. The ST-A builds on the AirCurve 11 ST with higher pressure capability and iVAPS™ (intelligent Volume-Assured Pressure Support) with AutoEPAP — adaptive, self-adjusting ventilatory support. It supports COPD, neuromuscular disease (NMD), obesity hypoventilation syndrome (OHS), chest-wall disorders, and central sleep apnea. Integrated HumidAir™ 11 humidifier, color touchscreen with QuickNav, and cellular connectivity to AirView. This is a clinician-configured ventilator (not a consumer CPAP). The Tri-Pack is a provider/clinical bulk pack of three devices.
Important — clinician-directed device
The AirCurve 11 ST-A is a bilevel noninvasive ventilator, prescribed, configured, and monitored by the patient’s clinical/respiratory-care team. Therapy modes, pressures, backup rate, alarms, and interface are determined clinically. HCPCS E0470 / E0471 (bilevel, with/without backup rate).

What’s included (per device)
- AirCurve 11 ST-A device (Air11 platform)
- HumidAir 11 integrated humidifier (standard + cleanable tub)
- ClimateLineAir™ 11 heated tubing (or SlimLine™ tubing)

The Tri-Pack contains three complete units (part 51203). Masks sold separately.
About the device
The AirCurve 11 ST-A is ResMed’s top bilevel/NIV in the Air11 generation — for patients who need more than standard PAP:
- Therapy modes — CPAP, S (Spontaneous), ST (Spontaneous/Timed), and iVAPS (with AutoEPAP). S/ST pressure range 3–25 cmH₂O.
- iVAPS with AutoEPAP — auto-adjusts pressure support to maintain each patient’s target minute ventilation (tidal volume + respiratory rate), while automatically adjusting expiratory pressure (EPAP) within preset limits to help prevent upper-airway obstructions — with an intelligent auto backup rate synchronized to the patient’s breathing. (iVAPS is indicated for patients ≥30 kg / 66 lb.)
- Advanced synchrony — higher cycle-sensitivity options for a broader range of chronic obstructive conditions, plus adjustable Fall Time for a smoother, more comfortable transition to expiratory pressure.
- Touchscreen + QuickNav — intuitive color touchscreen; instantly toggle between Settings and Monitoring to see how settings affect ventilation.
- Climate Control — integrated HumidAir 11 humidifier + ClimateLineAir 11 heated tubing deliver consistent temperature and humidity (prevent dryness and rainout).
- Connectivity — integrated cellular to AirView for remote monitoring/management (Care Check-In with patient consent).
Key features
- ResMed AirCurve 11 ST-A — Tri-Pack of 3 (51203).

Frequently asked questions
What is a Tri-Pack?
A bulk pack of three AirCurve 11 ST-A devices (part 51203) — intended for providers/DMEs stocking multiple units. Each is a complete system.
Is this a CPAP machine?
No — it’s a bilevel noninvasive ventilator, configured by a clinician. It includes a CPAP mode among its therapy modes but is not a consumer CPAP.
What makes the ST-A different from the ST?
The ST-A adds higher pressure capability and the iVAPS mode with AutoEPAP (adaptive, volume-assured support) on top of the ST’s spontaneous/timed bilevel with backup rate.
Who is it for?
Non-dependent patients with complex respiratory needs — COPD, neuromuscular disease, OHS, chest-wall disorders, and central sleep apnea.
Do I need a prescription?
Yes — this is a clinician-directed device. Contact us to confirm requirements and configuration.
How is it delivered?
Given the clinical nature and the multi-unit pack, please contact us to confirm availability, configuration, and delivery.
The AirCurve 11 ST-A is a clinician-configured bilevel ventilator. Modes, pressures, backup rate, and interface are set by the patient’s clinical team. This listing is informational and is not medical advice.
