Think happy thoughts
Jerry's dad was scheduled to undergo open heart surgery (two bypasses and a valve reconstruction) when his heart stopped. Because he is in a first-rate heart facility, they got it started again.

Several times.

There appears to be no brain damage, and they intend to go ahead with the surgery as planned. The risks just increased dramatically, but there is really no other option.

Jerry is in Albuquerque now. Prayers and happy thoughts are encouraged.

(I've just posted this same update to Milblog: I imagine further updates will appear there as well.)
