Can you purchase a CPAP machine?

Continuous positive airway pressure (CPAP) machines are currently the most recommended treatment for obstructive sleep apnea, and patients often feel major improvement after using them for just one night.

Your prescription can be filled at a sleep clinic or another equipment retailer. It should include the following details.

The type of device—CPAP, BiPAP, or APAP, for example.

It can be generic, rather than a name brand or specific model, with some exceptions. Most CPAP machines are interchangeable and it may take some time to find the best one.
The correct pressure level. These levels are set before you receive the machine and should only be adjusted by a doctor or technician, never by the patient.

With your machine, you’ll usually receive a six-foot hose and carrying case. Doctors might also include a note for a heated humidifier, which makes the harsh airflow more tolerable and reduces side effects such as dry throat and nasal congestion. You can buy a humidifier without a specific prescription, but if it’s included on your slip you’ll be sure not to overlook it. Masks and other accessories can also be sold without a prescription.

Getting a CPAP machine

Many centers are equipped to provide you with a CPAP machine immediately after your sleep study, or they can refer you to a local durable medical equipment (DME) supplier that sells or rents them. They’ll also fit you for a mask and show you how the whole system works together.
