Hi K.-
I am very familiar with apnea...preemie twins (29 weeks 3 days) who will be 15 years old in october!
Anyway, they will no doubt release him home on an apnea monitor. There will be a 'belt' that goes around his chest...or 'little stickies' that go on his chest (depends on his size). The monitor is L O U D...to the extent with my girls, if there was an apnic (sp?) episode...the sound alone pretty much got them back breathing regularly. The machine I had would keep alarming until situation resolves...ie...moving the probes if one had fallen off etc. The machine was 'downloaded' as per pulmonologist recommendations. You will also probably required to take an infant CPR course before his release if you haven't had one already (A good idea for ANYONE IMHO....)
This is SO common for preemies that I am shocked he did not go home with a monitor to start...
Not to frighten you, but I would also inquire about the rsv 'vaccine' in his case...years ago it was several IV infusions...now I think it is called 'respigam' (sp?) and is easier to administer. He is at risk because of his lungs...and the time of year...Worth it to bring it up if they don't...It is pricy...but I got my insurance to cover it for my more challenged ex preemie after she was considered by them to be 'too old'...
I send healing thoughts your way...feel free to private me!!
Best Luck!
