Thanks for the thoughts and suggestions. We did the bleach thing with the CPAP and he has new tubing and mask. He sees the FNP again today. He may just take longer to shake this.
I won't say that your thoughts are impossibel. I will say that there is a REALLY nasty para flu virus going around here. It looks like the flu only the swab is negative. Just guessing, but that is what I would think it is. My family got over it in 3 - 4 days. However, I ran a fever for 16 days and was almost hospitalized twice. I always tend to get harder with bugs than other people because of my asthma though.
I would definitely suggest that you clean the CPAP for him for a few days so that he doesn't just keep breathing his own germs back in.
Praying he feels better soon.
