You are welcome. It may not be his situation at all, I hope it isn't but after 5 years of caregiving for my husband I often wished I had pushed him a little more. Do yourself a favor insist he go plus other test. You will be thankful you did. A c-pap is much easier to clean etc than pushing him in a wheelchair. Forgive me for being straight forward. I'm tired. I care about you and your husband even though we haven't met. Blessings to you both!!
