Vital Signs

Definition

The basic measurements that tell doctors you are alive — temperature, pulse, blood pressure, and breathing rate — which seems like a low bar until you are in a hospital and being alive is genuinely the first thing they need to confirm.

Example Usage

"The nurse took my vital signs and said everything looked normal, which was the best review I have gotten since my mom said my painting was refrigerator-worthy in third grade."
