Today he really surprised us, we did a trial of a couple of hours on only his nasal canula instead of the bipap vent mask nor the rebreather mask. Much to our amazement he was wide awake and happily maintaining high O2 levels and a comfortably low heart rate which meant his body was at ease with the canula. From his demeanor we could plainly see how content he was without his entire face covered up with all that equipment!! What an amazing string of improvements he has made these past couple of days! We are so proud of him!
