Mary,
Darcey used a nasal pillow with her Trilogy BiPAP for daytime use... and WHILE using Dragon. I can't stress enough how important the microphone is. Dragon has a recommended list. If the one that you are using is not on that list, that might be your problem. I have a Sennheiser Wireless Headset that Darcey used successfully until her voice was no longer strong enough to be recognized. They are expensive. So, I would be glad to send that to you to try, if you would like to see if that might help.
I also believe that I have two of the hand pumps that I used for the Roho. I'd be glad to look for and send you one of them for you to keep. Just let me know if that might be a help.
Also... for anyone interested... I have just received our Large Liko Hygiene Sling back from the last person who had borrowed it. Once I run it through the wash, it'll be ready for the next person who would like to try it out. Just let me know.
If I can help with anything more, just give a shout!
Always, my best...
Jim
