Your DME can provide an auto CPAP even if the prescription specifies a single pressure. The machine would have to be set to manual CPAP mode for the prescribed pressure. It can be changed to auto CPAP later if necessary.
They will make less money so they won't want to give you the auto machine. If your DME is part of a chain, their corporate management may not allow it.
If you have your doctor rewrite the prescription, try to have him specify a range of pressures. The DME may resist dispensing an auto machine if there's not an autopressure range. If he resists having autopressure, see if he'll prescribe a small range. For instance, if he wants 10 cmH20, prescribe 8-12 cmH20. The DME can't dispense a manual CPAP if the script specifies a pressure range.
If it's midnight and the DME tells you it's dark outside, check for yourself. One BIG LIE that DMEs use is "this machine is data capable." They love to sell you machines that record only the hours of use. They'll even show you the data card, but all it tells you is when it was turned on for some machines.
Do not accept:
Any Respironics machine that doesn't say "Philips Respironics." If it doesn't say "Philips," it's an older, less capable model.
ResMed machines that don't say "S9" on the back are also older models.
PRS1 "Plus". Remember "PLUS is a MINUS."
Resmed S9 "Escape" or "Escape Auto." Remember, "If it says ESCAPE, run away and try to escape."
PRS1 Pro (not PLUS) is a good manual CPAP with full data. PRS1 Auto is a PRO machine with Auto CPAP.
I would not accept the PRS1 "AutoIQ" or "PRO AutoIQ," because it's not really an AUTO CPAP machine.
ResMed S9 Elite (NOT Escape) is a good manual CPAP. The S9 AutoSet (NOT ESCAPE AUTO) is an Elite machine with Auto CPAP.
Be careful if the DME says it's an "S9 AUTO." You need "AutoSET."
PRS1 machines have the model name above or below the display.
S9 machines have the model name near the on/off button.
