Acid Reflux?

I'm starting to think that Greyson's problems involve some serious acid reflux. His stats dropped and he got really fussy and then he let out a huge burp and seemed much better. They are putting the High Flow Nasal Cannula on him right now and I decided to stop out of the room - it gets really crowded.
If this HFNC doesn't help they may start him on some meds for reflux. I just want something to work.

UPDATE: Well, they put the HFNC on and while the Respiratory Therapist said that Greyson fussed the whole time he was doing much better when I left. I hope he keeps it up!
