CPAP Machines

CPAP machines are considered the "gold standard" for the treatment of obstructive sleep apnea, sleep disordered breathing, and snoring. CPAP is an acronym for continuous positive airway pressure. It works by filtering out room air and delivering pressurized air that keeps your airway open during sleep. Heated humidifiers are available and recommended to prevent dryness that can be caused by direct pressure. Our CPAP machines are available in standard and auto-adjusting models.

CPAP, APAP, and BiPAP - What’s the Difference?


Each is a type of PAP therapy that uses a machine, mask, and tubing to provide pressurized air to a patient and to treat sleep apnea.

    A standard CPAP machine delivers one pressure setting (steady or constant) during the night. See fixed pressure CPAP machines.
    An APAP or auto-adjusting CPAP machine detects when the airway closes and automatically adjusts the pressure accordingly. This machine has an auto or fixed pressure mode.
    A BiPAP or bi-level machine has two pressure settings, each for inhalation and exhalation.

Can I Buy a CPAP Machine?


Yes, you can buy a CPAP machine with a prescription. This is in line with the Food and Drug Administration’s (FDA) classification of positive airway pressure delivery systems as Class II medical devices for prescription use only.

We use the prescription to adjust or to program the device’s settings as prescribed. Items, such as CPAP masks without headgear, CPAP mask parts, and CPAP machine parts, do not require a prescription for purchase.

For more information, here’s our prescription policy.

What Are the Side Effects of Using a CPAP Machine?


You may encounter issues when undergoing CPAP therapy. Common side effects may include:

  • Dry nose, mouth, or throat
  • Nasal congestion
  • Discomfort
  • Claustrophobia
  • Skin allergies or irritation
  • Aerophagia (excessive air swallowing)
  • Dizziness or headache
  • Shortness of breath
  • Stomach bloating

Prevent side effects by choosing the best type of CPAP mask (full face masks, nasal pillow masks, nasal masks), cleaning your machine and mask to avoid infection, and carrying out strategies recommended by your physician.
