Formula & Worked Example

The math behind the Blood Pressure Classifier

Mathematical Formula

MAP = DBP + \\frac{SBP - DBP}{3}
**ACC/AHA 2017 Guidelines**: - **Normal**: SBP < 120 AND DBP < 80 - **Elevated**: SBP 120–129 AND DBP < 80 - **Stage 1**: SBP 130–139 OR DBP 80–89 - **Stage 2**: SBP ≥ 140 OR DBP ≥ 90 - **Crisis**: SBP > 180 OR DBP > 120 - **Pulse Pressure** = SBP − DBP (normal 30–60 mmHg) - **MAP** normal range: 70–100 mmHg

Step-by-Step Worked Example

Blood pressure reading: **135/85 mmHg**: - Category: **Stage 1 Hypertension** (SBP ≥ 130) - Pulse Pressure = 135 − 85 = **50 mmHg** (Normal) - MAP = 85 + (135 − 85)/3 = **102 mmHg** (slightly elevated) - Action: Lifestyle changes + consider medication
