HelloCustomer and thank you for using


I called Fisher&Paykel (1-800-446-3908) and they informed me that the air pressure can only be changed by the doctor who prescribed the respirator, since its use is under the physician prescription.


I'm sorry but I'm afraid that only your primary care physician can do that.


If that information was helpful, please accept this answer.


Thank you,
