Blood Pressure & MAP Calculator
Assess your blood pressure category and calculate Mean Arterial Pressure (MAP).
Understanding Your Blood Pressure Reading
Blood pressure is measured using two numbers: Systolic and Diastolic. Systolic blood pressure measures the pressure in your arteries when your heart beats. Diastolic blood pressure measures the pressure in your arteries when your heart rests between beats.
Mean Arterial Pressure (MAP)
Mean Arterial Pressure (MAP) is considered the average pressure in a patient's arteries during one cardiac cycle. It is often considered a better indicator of perfusion (blood flow) to vital organs than systolic blood pressure alone. A MAP of at least 60 mmHg is generally required to sustain the organs of the average person.
The MAP formula is: MAP = [Systolic + (2 × Diastolic)] / 3
Blood Pressure Categories
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120 – 129 | Less than 80 |
| Hypertension Stage 1 | 130 – 139 | 80 – 89 |
| Hypertension Stage 2 | 140 or higher | 90 or higher |
| Hypertensive Crisis | Higher than 180 | Higher than 120 |
Pulse Pressure
Pulse pressure is the difference between your systolic and diastolic blood pressure (Systolic – Diastolic). A pulse pressure greater than 60 mmHg is often considered a risk factor for cardiovascular disease, especially in older adults.
