inquiry on resmed s7 pressure gain setting

[jacksonville]

I have been on cpap since 1991. usualy I can just about search and find anything I need to
know. I have a resmed auto set for home use. (yes, I program it myself) I recently acquired a resmed s7 for traveling. I went into clinical setup and set to 17.0 cm H20....the next option was pressure gain. it wouldnt change....I have looked all over for information on this setting. can anyone help ?

This is just a guess on my part...

I'm guessing the "pressure gain" setting has to do with adjusting the pressure delivery, if you checked the pressure with a manometer, found it to be a bit "off" and not actually delivering the amount of pressure the machine said it was delivering. But, I may be wrong about that since you say you've not been able to change that particular setting.

Anyway, this was in an old (2003) issue of rt magazine:

CPAP Flow Generator
ResMed Corp, San Diego, has added the S7™ Lightweight to its family of flow generators for the treatment of obstructive sleep apnea. A fixed CPAP flow generator, it features ResMed’s modular humidification system and gross-altitude and fine-gain adjustment for accurate pressure delivery.

The part I emphasized in bold red is what makes me think the adjustment you described is ... what I think it is.

Perhaps you could take the machine to a kindly DME who would take the few moments needed to give the machine a quick check with a manometer. If I couldn't find a DME willing to do that for free, I'd not worry about it.
