Renal

Erika wants me to explain what "renal" means.

Renal is a sensor on the kidney, tracking blood flow and oxygenation to that organ. When the number dives, the body is deciding to take care of the brain and heart first, and is choosing not to send nutrients to that organ to help the heart and brain.

So...now that it's 94, it means the body has enough good stuff to share with heart, brain, kidneys...and beyond!
