The Role of Units in Accuracy While some regions use alternative units like kilopascals (kPa), the mmhg scale remains the predominant language in clinical guidelines. Hypertension Stage 2: Systolic at least 140 or diastolic at least 90 mmhg.
Understanding mmHg Units in Clinical Guidelines
Global Context and Standards Although the metric system dominates global measurements, pressure in mmhg persists due to historical precedent and research data. Precision is vital; a difference of 10 mmhg can shift a diagnosis from normal to hypertensive.
Historically, this unit was derived from mercury manometers, devices that translated internal pressure into a visible vertical column of liquid metal. This unit, millimeters of mercury, serves as the standard measurement for pressure within the arteries during the cardiac cycle.

The systolic number, displayed first, represents the force in the arteries when the heart contracts and pumps blood. Familiarity with mmhg empowers patients to navigate medical literature and international health recommendations effectively.
