CPAP machine and mask according prescription

Hi,
I live in Canada, but I want to buy CPAP machine and mask in US (http://www.secondwindcpap.com/). There is much, much cheaper and I don't have any insurance for it etc.

In my prescription only one short phrase: "CPAP Auto 5-18 H2O"

Will ResMed S10 AirSense AutoSet with EPR + be OK with the prescription?
Additionally, I would like to use ResMed AirFit P10 - is it OK with the pressure (I am not asking about comfort etc)?

My second choice
Machine: Respironics DreamStation Auto CPAP with Heated Humidifier - DSX500H11
Nasal pillow: ResMed Swift FX or Swift FX

Thank you in advance.

P.S. I don't have any other diseases or conditions. My weight is normal. I prefer to sleep on my side. I have a mustache and beard (Spanish style).



My sleep investigation:

--

Yes, the ResMed AirSense 10 AutoSet will be fine with your prescription settings.
And yes, the P10 mask will work just fine at any pressures.
Good choices.
