Trachs and Vents 101--The Pulse Oximeter

pulse ox
The pulse oximeter (ox-im-eat-er), lovingly referred to as the pulse ox, is another important little machine in our lives these days.  It measures the amount of oxygen Abby is getting, and the higher, the better!  We want 100%, or as close to it as we can get.  It alarms at 94%, but she usually isn't any lower than 98%.  It also measures her heart rate, which alarms if it drops below 80 or goes higher than 200.  Neither of these happen very often at all, so we're mostly concerned with her oxygen levels.

The probe is attached to a band-aid kind of a thing that wraps around the foot or hand.  We just do the foot because she moves her hands too much to get a good read. 

In those scary early days in the NICU, the pulse ox didn't even alarm until 82% because Abby's baseline was in the mid to upper 80s (yeah, I know---not so hot!)  When the percentage drops down below the alarm parameter, it's called a desat.  This is short for desaturation, which means that Abby is not getting enough oxygen to her brain.  It wasn't uncommon for Abby to desat to the 30s fairly often, which would require lots of stimulation, oxygen, and praying.  In the beginning, she desated soooo frequently (like 10+ times an hour) that she had a nurse strictly assigned to her.  I knew things were getting better when her nurse had another baby to take care of! 

Thankfully, those days are LONG over (I shake my head in amazement at just how far God has brought us when I stop to think of those early NICU days) and now Abby's idea of a desat is to maybe 90%.  That, I can handle!

So that's the pulse ox's job.  Abby only has to wear it when she's sleeping.  Otherwise, her kicking sets it off and keeps it from getting a good read anyway.  Yep, this is another boy-who-cried-wolf alarm, just like the apnea monitor.  This one isn't as ridiculously loud though, and it's easy to take off if we need to give her foot a break.

I enjoy these '101' lessons and am continually in awe at the level of knowledge and understanding you must have to care for and respond to Abby's needs. It is also interesting to hear what some of her levels were in the NICU and how far Abby has come - understanding things better, including the numbers, I can only say that you are amazing parents(and of course you know your family is also amazing). And, then we can never forget our Lord who has never left anyone's side during this period; He is truly amazing in how far he has brought this precious jewel and her family.

And so I ramble, but I must add that now when I look at this weekend's pictures of Abby w/her toy, doing reps and chewing on it, (all the normal things a growing baby does), one's heart can only become bursting with joy (yes JOY)!

Have a great week

:)

All those desats scared me in the NICU! I was only there an hour but prayed through 10 or more and watched in fear & amazement as you and the nurses rubbed her back and held her hand till the level went back up. God has brought her so far! And brought you guys too!

Cerebrocostomandibular Syndrome

If you happen to pick up the latest Reader's Digest, there is an article in there about Piper Breinholt , a four year old with CCMS.  If you've been around here a while, you'll remember wayyyyyy back when we first received Abby's diagnosis that I was able to speak to Piper's mom, Reagan.  The article is more about their story and not as much about the ins and outs of CCMS, but I think it's probably enough to get some people googling it and I'm hoping a few will end up here. Every once in a while, I give a blog post the title of Cerebrocostomandibular Syndrome so that it would show up in Google.  My ever-present hope is that people will stumble across my blog and 1) be encouraged by the hope we have in Christ, 2) feel a connection with someone in a similar situation as them, or 3) get excited over the miracles that have been performed in Abby's life!!  (a combination of all 3 is great too!)  :)   Notice that it's not to get famous and it never wi

The Potty Man

Caleb LOVES to go potty! I have never heard a potty training story like this one....Caleb tells us when he needs to go, we take his diaper off, and he goes! Now, is it perfect? No, not at all! We aren't trying to potty train at at all, but we figure every time he goes is one less diaper we have to change! The only time we consistantly put him on the potty is when we give him a bath (he always pees in the tub, so we know he needs to go!) He almost always goes on the potty now instead of the tub though. When he's not "really" going potty, he's pretending to go potty! He's such a funny kid!

Lego Party: Favors

I'm a little slow in posting the Lego Party pictures, but I think I have a few excuses I could use.  At any rate, I wanted to share what I did for the party!  It will take a few posts, so stay with me.  I'll start with how I did the favors. These are the goody bags I made.  I just bought solid colored gift bags and matched scrapbook paper to each bag.  Then I punched circles and attached them with the 3D foam tape so that the circles were raised. I used the keychain (explained below) as a name tag on the outside. These are Duplo blocks.  I put a round magnet on the back and...voila!  A magnet!  (note:  hot glue doesn't work so well...I ended up reglueing them with my apoxy because the magnets fell off.) I made crayons using Lego man crayons.  Yes, I know this guy has lost half of his leg.  The others were already packaged and I didn't want to open one up just to get a picture.  I used a Lego mold  to make the crayons.  Caleb put small pieces of crayon in each m
