What is an AVAPS Machine?

Average volume-assured pressure support (AVAPS) is a relatively newer modality of non-invasive ventilation that integrates the characteristics of both volume and pressure-controlled non-invasive ventilation.

AVAPS is designed specifically for taking over the control of and adapting automatically to each patient’s changing therapy needs. It is a noninvasive home ventilator that provides the patient with the accurate pressure volume required to maintain adequate treatment.

Philips CPAP / AVAPS Recall

In June 2022, Philips Respironics announced a voluntary recall of millions of Philips CPAP, BiPAP, AVAPS and Ventilator machines due to potential health risks, including potential cancer risk.

The Philips CPAP recall is related to the polyester-based polyurethane (PE-PUR) sound abatement foam used in the affected devices. The PE-PUR foam can reportedly degrade into small particles that can be inhaled or ingested, or emit chemicals that pose health risks including possible carcinogenic effects.

Which AVAPS Were Recalled?

Continuous Ventilator, Non-life Supporting

  • DreamStation ASV
  • DreamStation ST, AVAPS
  • SystemOne ASV4
  • C-Series ASV
  • C-Series S/T and AVAPS

AVAPS Side Effects

Philips Respironics has received reports of possible patient impact due to foam degradation in recalled Philips AVAPS machines.

The potential health risks of particulate exposure in a defective Philips AVAPS, CPAP, sleep apnea machines, ventilator devices, and other similar medical devices include:

  • Headache
  • Irritation
  • Inflammation
  • Chest pressure
  • Respiratory issues
  • Toxic effects
  • Cancer (carcinogenic effects)
  • Other health issues

Potential risks of chemical exposure due to Philips breathing machines off-gassing include:

  • Headache
  • Irritation
  • Hypersensitivity
  • Nausea/vomiting
  • Sinus infection
  • High blood pressure
  • Toxic effects
  • Carcinogenic effects


Although both AVAPS and BiPAP are reliable in the treatment of acute hypercapnic respiratory failure, AVAPS is associated with a speedy improvement of the patient clinically. The patients have also experienced greater comfort and satisfaction comparatively, and therefore, improved treatment compliance.

What Should I Do If I’m Using a Recalled Philips AVAPS Device?

If you or a loved one are using one of the recalled Philips AVAPS machines, Philips says you should speak with your physician to figure out the best options for continued treatment.

“Philips recognizes that alternate ventilator options for therapy may not exist or may be severely limited for patients who require a ventilator for life-sustaining therapy, or in cases where disruption is unacceptable,” the recall notice states. “In these situations, and at the discretion of the treating clinical team, the benefit of continued usage of these ventilator devices may outweigh the risks.”

The company has begun replacing the PE-PUR foam in the recalled AVAPS machines with new material.

Tell your doctor about any symptoms you have that may be related to the use of a recalled Philips CPAP machine.

So far, dozens of Philips AVAPS lawsuits have been consolidated into multidistrict litigation (MDL) and sent to a Pittsburgh federal court.
