計算式
Formula: Categories: Normal < 120/80, Elevated 120-129/<80, Stage 1 130-139/80-89, Stage 2 ≥ 140/90. MAP = (SBP + 2×DBP) / 3.
よくある質問
What is normal blood pressure?
Normal blood pressure is below 120/80 mmHg. The top number (systolic) measures pressure during heartbeat. The bottom number (diastolic) measures pressure between beats.
What is mean arterial pressure?
MAP represents the average pressure in your arteries during one cardiac cycle. A healthy MAP is between 70-100 mmHg. It is calculated as (Systolic + 2 × Diastolic) / 3.
When should I seek medical help?
Seek immediate medical attention if systolic exceeds 180 or diastolic exceeds 120 (hypertensive crisis). Consistently elevated readings above 130/80 should be discussed with your doctor.
