I played the blueprint 3 times in the ER yesterday
I was also lucky to meet a professional nephrologist
The ICU doctor just said
Dad’s serum potassium ion was 7.1 yesterday
Dropped to 6.5 today
Target 5.1 best
Observe for another 1~2 days
If there is a drop to 5.1
transfer to general ward
Again, thank you @Dreamweaver
