Many customers of The MedEquip Shop ask, “what is the difference between a CPAP machine and an APAP machine?” The answer is simple.
A CPAP machines offer Continuous airflow throughout the night with an average pressure of 10cmH2O. This pressure is about what is needed to keep a person’s airways open and to prevent sleep apnea.
The APAP is like the CPAP in most circumstances, one of the only differences is that an APAP changes the air pressure depending on the patient. It does not do this for any medical reason besides to make sure that the patient is comfortable while sleeping. You may now ask, “ why would I get a CPAP, if the APAP is more comfortable?” The simple answer is, the APAP is much more expensive, but it may not be needed for your condition, please consult your doctor for further information.
Frequently asked questions
What is the main difference between CPAP and APAP?
CPAP delivers a fixed prescribed pressure. APAP adjusts pressure within a prescribed range in response to breathing needs during sleep.
Does an APAP machine change pressure during the night?
Yes. An APAP device can adjust pressure as breathing needs change. Its permitted pressure range should be set according to the clinician’s prescription.
Does everyone use the same CPAP pressure?
No. Therapy pressure is individualized. Use the settings prescribed for you and consult your healthcare provider if treatment is uncomfortable or symptoms persist.
Is APAP always the better choice?
No. The appropriate device depends on your diagnosis, treatment needs, and response to therapy. Discuss CPAP and APAP options with your clinician.
How can I compare CPAP and APAP machines before buying?
Compare the prescribed therapy mode, comfort features, compatibility, and cost. MedEquip Shop can explain product options, while your clinician determines the appropriate therapy.
