How Blood Pressure Works
- Blood pressure is the driving force that propels blood and delivers oxygen and nutrients to tissues.
- It has two components: systolic (when the heart beats) and diastolic (between beats).
Know Your Target Numbers
- Aim for systolic <120 and diastolic <80 to be in the normal range.
- Recognize 120–129 systolic is 'elevated' and ≥130/80 meets the current hypertension definition.
When Low Blood Pressure Matters
- Very low blood pressure can cause inadequate organ perfusion and symptoms like lightheadedness.
- Generally, BP <90/60 is considered low but some people tolerate it fine.
