🔍 Quick Summary
Blood pressure monitoring helps track how hard your heart is working.
Regular checks can detect problems early—even before symptoms appear.
1️⃣ Introduction
Blood pressure is the force of blood pushing against artery walls.
• measured using two numbers (systolic/diastolic)
• changes throughout the day
• important indicator of heart health
👉 Many people with high blood pressure feel completely normal.
2️⃣ Breakdown
Blood pressure depends on heart function and blood vessels.
• systolic = pressure when the heart pumps
• diastolic = pressure when the heart relaxes
• influenced by stress, activity, and health conditions
👉 Monitoring helps detect patterns—not just single readings.
3️⃣ Classification
• Normal blood pressure
- within healthy range (below 120/80)
- stable readings
• High blood pressure (hypertension)
- consistently elevated readings (more than 120/80)
- increased health risk
👉 Trends over time matter more than one reading.
4️⃣ Common reasons to monitor
• Routine health checks
- early detection of hypertension
• Existing conditions
5️⃣ Symptoms
• often no symptoms
• may feel normal even when elevated
👉 This is why it’s called a “silent” condition.
6️⃣ Associated signs (if severe)
• headaches
• dizziness
• blurred vision
• chest discomfort
👉 These may appear only when levels are very high.
7️⃣🩺 When it becomes dangerous 🚨
• very high readings (e.g. ≥180/120 mmHg)
• symptoms like chest pain
• shortness of breath
• confusion
• vision changes
👉 These may indicate:
• hypertensive crisis
• need for emergency medical care
8️⃣ How to monitor correctly
• rest for 5-10 minutes before measuring
• sit upright with arm supported
• avoid caffeine/exercise just before
9️⃣ Diagnosis
• repeated measurements over time
• home monitoring or clinic readings
• evaluation of risk factors
👉 Diagnosis is based on consistent readings—not one result.
🟢 Important message
Regular monitoring helps detect problems early.
👉 Knowing your numbers helps you stay in control of your health.
