What is Blood Pressure?
Blood pressure measures the force exerted by circulating blood against arterial walls. It consists of systolic pressure (heart contraction) and diastolic pressure (heart relaxation), providing crucial cardiovascular health information.
Cardiovascular Science
Blood pressure regulation involves complex interactions between cardiac output, peripheral resistance, blood volume, and arterial compliance. The renin-angiotensin-aldosterone system, sympathetic nervous system, and endothelial function all influence blood pressure control.

Blood Pressure Categories (AHA 2017)
🔬 Physiological Factors
- • Cardiac output (stroke volume × heart rate)
- • Peripheral vascular resistance
- • Blood volume and viscosity
- • Arterial elasticity and compliance
- • Autonomic nervous system activity
⚠️ Cardiovascular Risks
- • Coronary artery disease (2x risk at 140/90)
- • Stroke risk (4x higher with hypertension)
- • Heart failure development
- • Kidney disease progression
- • Peripheral arterial disease
- • Retinal damage and vision loss
🩺 Blood Pressure Analysis Examples
Example 1: Normal Blood Pressure
Reading: 115/75 mmHg, Age: 35, No risk factors
Category: Normal
Pulse Pressure: 115 - 75 = 40 mmHg
MAP: 75 + (40/3) = 88 mmHg
Risk: Low cardiovascular risk
Action: Maintain healthy lifestyle
Example 2: Stage 1 Hypertension
Reading: 135/85 mmHg, Age: 55, Diabetes
Category: Stage 1 Hypertension
Pulse Pressure: 135 - 85 = 50 mmHg
MAP: 85 + (50/3) = 102 mmHg
Risk: High (diabetes + HTN)
Action: Immediate medical consultation

❓ Frequently Asked Questions
What's the difference between systolic and diastolic pressure?
Systolic pressure (top number) measures arterial pressure when the heart contracts and pumps blood. Diastolic pressure (bottom number) measures pressure when the heart relaxes between beats. Both are important for cardiovascular health assessment.
How often should I check my blood pressure?
Adults should have blood pressure checked annually if normal. Those with elevated readings need more frequent monitoring (monthly to quarterly). People with hypertension may need daily home monitoring during treatment adjustment.
What factors can temporarily affect blood pressure readings?
Caffeine, exercise, stress, full bladder, talking, arm position, cuff size, and recent meals can all affect readings. For accurate measurement, rest 5 minutes, avoid caffeine 30 minutes prior, and use proper technique.
⚠️ Limitations & Considerations
- • Single Reading: One measurement insufficient for diagnosis; trends more important
- • White Coat Effect: BP may be elevated in medical settings
- • Age Considerations: Normal ranges may vary for elderly patients
- • Pregnancy: Different BP targets and considerations during pregnancy
- • Arm Differences: BP can vary between arms; use higher reading for assessment
- • Medical Conditions: Some conditions affect accurate measurement (arrhythmias, arterial stiffness)
