RR stand for blood pressure.
A normal resting blood pressure reading is 120/80.( RR 120/80 )
were as systolic 120 and diastolic 80,
Systolic pressure (the first and highest number) is the pressure or force the heart places on the walls of your blood vessels as it is working/pumping with each heartbeat.
Diastolic pressure (the second and lowest number) is the lowest pressure the blood places on the walls of your blood vessels when the heart is relaxed between beats.
Both of these measurements are important. A high systolic pressure indicates strain on the blood vessels when the heart is attempting to pump blood into your bloodstream. If your diastolic pressure is high, it means that your blood vessels have little chance to relax between heartbeats.

RR could be respiratory rate, or R-R interval on EKG/ECG. 120/80 is the blood pressure possibly, good luck
