What is Blood Pressure Analyser?

▾

Blood pressure is the force of blood pushing against artery walls. Systolic (top number) is pressure during heartbeat; diastolic (bottom number) is pressure between beats. Normal: below 120/80 mmHg. The AHA classifies five stages from normal to hypertensive crisis.

How to Blood Pressure Analyser

▾

1Pulse pressure = Systolic − Diastolic
2Mean arterial pressure (MAP) = Diastolic + (Pulse pressure / 3)
3Normal MAP: 70–100 mmHg
4MAP < 60 mmHg → inadequate perfusion to organs

Worked Examples

▾

Example 1

Given:120/80 mmHg

Výsledok:Normal · PP=40 · MAP=93 mmHg

Ideal blood pressure

Example 2

Given:145/95 mmHg

Výsledok:Stage 2 hypertension · PP=50 · MAP=112

Medication usually indicated

Elevated	120–129	< 80
Stage 1 high	130–139	80–89
Stage 2 high	≥ 140	≥ 90

Pro Tip

Measure blood pressure after 5 minutes of seated rest, twice per session, in the same arm each time. One reading means very little — trends over many readings are what matter.

Did you know?

Blood pressure naturally follows a circadian rhythm — it dips 10–20% during sleep (dipping) and rises sharply in the morning. This "morning surge" is associated with increased risk of heart attack and stroke.
