What does RR mean?
When talking about blood pressure, you'll often come across the abbreviation RR. It stands for Riva Rocci and is commonly used in medicine to refer to blood pressure.
The most common way of measuring blood pressure today is still very similar to the Italian doctor's method. An air-filled cuff briefly stops blood flow in a vessel and a pressure gauge then measures the blood pressure. Feeling the radial pulse is used less often now, but it still has its placeespecially in emergency care. More commonly, clinicians listen for the Korotkoff sounds with a stethoscope or detect the oscillations in the blood vessel, as most electronic blood pressure monitors do.
Blood pressure is measured in mmHg (millimeters of mercury).
