What is CF?

Cystic Fibrosis is a genetic disease that affects the respiratory & digestive systems.  There is excessive thick mucus that clogs the lungs and blocks enzymes from reaching the intestines for food digestion.

Can you "catch" CF?

No!  It's a genetic disease so you can only get CF if both parents pass you the CF gene.  You can be a carrier of the gene and not have CF.
Here's a matrix I learned to show who can get CF:
Both Parent 1 and 2 are carriers of the CF defective gene (CF).   If only one parent is a carrier, then they cannot have a child with CF, but can pass on the defective gene.

Parent 1

CF=Defective CF gene
Parent 2

SmartVest Review & CF Appointment

Well, here is the long awaited official review of my new SmartVest SQL.  I don't have any current or updated vests to compare this too, so my feed back is based upon what I like/dislike versus the old and out-dated vest.

Pros:
Weight - it is MUCH lighter than my ancient Hilrom Vest.  By all means, it isn't light but definitely a great improvement from my older model.  I can at least carry it myself!Comfort of vest - the fabric is much softer and less scratchy when wearing it.Technology - it has a digital screen, so I can set the time and know for sure how long I'm using it (the old one had a knob to turn).  Also, I can set different programs based on how long I want to use it, etc.  It's quieter!!  Will still doesn't enjoy watching TV with me while I vest, but I don't have to turn the TV to its max volume!  And, the dogs aren't scared of this one as much!There is only 1 hose...so I'm not tangled up :)And it comes with a rolling case (that looks like a re…

CF Updates

I had my quarterly CF appointment on August 9th.  I left that day for WV, and forgot my notebook so I couldn't share all the numbers until I was back home.  And now, I'm home...watching the eclipse :)  It just happened, we were at 99% totality and it was pretty amazing to see!

So, here are the PFT results:

                          8/9/17                5/9/17               8/16/16                8/4/15
FVC                  101%                   99%                  99%                     94%
FEV1                  89%                   87%                  88%                     83%
FEF25-75%        61%                   62%                  64%                     57%

I'm happy! Glad that the FVC went over 100, just got to work on that FEV and get it back in the 90s.   I was on my 4th week of Cayston and feeling good for the appointment.

I did go early as I had to have my glucose test done - Yuck!  I'm sure that will be fine.

Nothing else to really report.  BMI is…

Pupdate

My little bully babies are growing up.  Sarge & Stella turned 6 at the beginning of July and T-Bone turned 8 at the end of July.

We celebrated Sarge & Stella's birthday at home with some special treats from the local pet store.  T-Bone got to be at his favorite place on his birthday (our cabin in WV).  Unfortunately I was a bad dog mom and forgot his birthday hat and treat, but he got extra loving and sang to multiple times.

T-Bone had his bi-annual check up just before his birthday and had a good report.  We are changing his eyedrops due to the formula change in what he was using - it was making his eyes red and itchy. And then, in his ear (not the one that just had surgery) we noticed a tick like thing in one of the folds. He got very irritated with us when we messed with it, so thankfully his appointment was the next day, so I figured I'd let them piss him off.  Turns out, its not a tick.  The vet said it looked just like the mass that he saw in his other ear cana…
