When a physician orders a pressure change, or a patient moves to an area with a very different altitude and does not have an altitude compensating machine, there are a number of ways to ensure you are receiving CPAP therapy at the correct pressure.
The first and most common way is to contact your Homecare Provider. The company that sold you your machine is normally more than willing to help you adjust your pressure.
A second way is to call the sleep laboratories and/or sleep disorder centre, as they may be willing to make this pressure change for you. Be sure to take your prescription.
It is the law and good common sense to run all sleep disorder devices at the prescribed pressure. If you think your prescribed pressure is wrong, talk to your physician.
