What is Blood Pressure Classification?

Blood pressure classification refers to the categorization of blood pressure levels based on systolic (SBP) and diastolic (DBP) values. This classification helps in identifying whether a person’s blood pressure is normal, elevated, or indicative of hypertension.

How is Blood Pressure Classification Determined?

Blood pressure classification is based on the following ranges:

• Normal: SBP < 120 and DBP < 80
• Elevated: SBP 120–129 and DBP < 80
• Hypertension Stage 1: SBP 130–139 or DBP 80–89
• Hypertension Stage 2: SBP 140–179 or DBP 90–119
• Hypertensive Crisis: SBP ≥ 180 or DBP ≥ 120

Example Classification

For a patient with SBP = 135 mmHg and DBP = 85 mmHg:

SBP = 135, DBP = 85
Classification = Hypertension Stage 1

This indicates the patient is in Stage 1 hypertension, which requires monitoring and lifestyle modifications.

Why is Blood Pressure Classification Important?

• Early Detection: Helps identify elevated blood pressure levels early for preventive care.
• Management: Guides treatment plans and lifestyle changes to control hypertension.
• Risk Assessment: Indicates the risk of heart disease, stroke, and other health complications.
