⚠ Two things to read before you buy
First the safety limit, then what “Certified Pre-Owned” means here. ASV therapy is CONTRAINDICATED in patients with chronic, symptomatic heart failure (NYHA class 2–4) with reduced left ventricular ejection fraction (LVEF ≤ 45%) and moderate to severe predominant central sleep apnea.
If ASV is right for you, this is the same therapy as the new unit for hundreds less — inspected before it ships, and supported by our team in Doral, FL.
The AirCurve 10 ASV (Certified Pre-Owned) is an adaptive servo-ventilation device prescribed for obstructive sleep apnea, central and/or mixed apneas and periodic breathing in patients over 66 lb. It learns your recent minute ventilation and adjusts pressure support breath by breath; in ASVAuto it also auto-adjusts EPAP. It includes an integrated heated HumidAir humidifier and works with ClimateLineAir tubing. American Oxygen inspects, tests and reconditions each unit, installs a new filter, and backs it with a 1-year warranty by American Oxygen — not the manufacturer. A prescription is required, and ASV is contraindicated in chronic symptomatic heart failure (NYHA 2–4) with LVEF ≤ 45% and predominant central sleep apnea. Ships from Doral, FL with any compatible mask at 10% off.
Certified Pre-Owned or new — which ASV should you buy?
| AirCurve 10 ASV (Certified Pre-Owned) | AirCurve 10 ASV (new) | AirCurve 11 ASV (new) | |
|---|---|---|---|
| Therapy | ASV · ASVAuto | ASV · ASVAuto | ASV · ASVAuto |
| Condition | Inspected, tested, reconditioned | Sealed, never used | Sealed, never used |
| Warranty | 1-year by American Oxygen | 2-year manufacturer | 2-year manufacturer |
| Air filter | New filter installed | New | New |

Quick pick: the therapy is identical on all three. Buy this one to spend the least on the same ASV night; buy new for the full 2-year factory warranty; buy the 11 if you need the higher oxygen limit or want the touchscreen.

Frequently asked questions
I have heart failure. Can I use ASV?
Not without your cardiologist’s clearance. ASV is contraindicated in chronic symptomatic heart failure (NYHA 2–4) with LVEF ≤ 45% and moderate to severe predominant central sleep apnea. Ask the clinician who prescribed it before you buy.
What does Certified Pre-Owned mean?
Each unit is inspected, tested and reconditioned by our technicians, fitted with a new filter, and backed by a 1-year warranty by American Oxygen. Low hours, cleaned and sanitised.
Is the warranty from the manufacturer?
No. The 1-year warranty is provided by American Oxygen, not the manufacturer. If you want the full 2-year factory warranty, buy the new AirCurve 10 ASV or the AirCurve 11 ASV instead — we sell all three.
Why doesn’t CPAP work for central apnea?
Obstructive apnea is a blocked pipe — air pressure alone can splint it open, which is why CPAP works. Central apnea is different: the airway is clear, but the signal to breathe doesn’t arrive. Pressure alone does nothing for that. ASV notices the missing breath and supplies the support for it.
Do I need a prescription?
Yes. ASV is a prescription device and the settings must come from your clinician. Masks, tubing and filters ship without a prescription.
Which mask should I use with it?
Most ASV users end up in a full face mask, because the pressures are higher and mouth leak breaks the therapy. Add one here at 10% off, or call us and we’ll pick it with you.
The same ASV night, for less.
Tell us what your prescription says and what your clinician told you — we’ll confirm this is the right device, and say so plainly if it isn’t.
