Update

This has all been quite a scare with an unknown outcome. I just got off the phone with Mom and dictated all of these seemingly good things:
Dad is showing slow steady improvement.
They are weaning him off the ventilator and hope to be done by this afternoon.
The Dr. from infectious disease is confident that they are treating him with the right combo of antibiotics.
His platelets are slightly better and his white blood cells are down a little (this is highly important).
The pulmonologist (lung Dr.) was positive about things turning in the right direction.
The cardiologist (heart Dr.) said that blood pressure and heart rate were okay- seeing slow steady improvement too. This is nice positive contrast to what he was saying two nights ago- whew.
The kidney stone is still there- we're not sure how it will be resolved- hopefully when it passes it won't cause too much stress on the heart and lungs.
Overall, once this grave blood infection is resolved, we'll know how much the heart was affected long term.
Dad slept decently last night, seems comfortable and isn't identifying any pain (back to the old thumbs up technique for communication! Tubes in the mouth aren't conducive to verbalizing).
Mom is a trooper as always. She's taking care of herself and getting sleep. We're trying to make sure she eats. Every health care professional at Paoli Memorial now probably knows her by name!
While Dad rested post procedure, we enjoyed a meal with everyone on the back patio at the house. Matt, John and Luis left to go back to DC last night. Now it's Jen, Greg and I with all of the kids. Woo hoo! There has been tremendous support from Mom & Dad's network of friends providing help with childcare and meals- a true godsend.
We hope these trends continue to be good and Dad's pain decreases steadily.
I hope to post later when Dad is hopefully off the ventilator and feeling comfortable.
Thanks again for everything.
