Settings for ResMed Adapt-SV S9 VPAP machines

I was given a new script and have been told by two different DME companies that it can’t be filled.

The proposed new settings are
epp 7,
psv min 7,
psv max 10

According to the techs the PSV min setting has no setting of 7. The PSV Min can be set only as high as 6.

Is that your understanding, as well?

The prescribing doctor and the dme respiratory therapist should be talking to each other about this.
