Understanding Blood Pressure

Blood pressure is the pressure of circulating blood against the walls of blood vessels. It is one of the vital signs along with respiratory rate, heart rate, oxygen saturation, and body temperature.

Blood Pressure Components
  • Systolic Pressure: The pressure when the heart contracts and pushes blood out.
  • Diastolic Pressure: The pressure when the heart relaxes and fills with blood.
Blood Pressure Categories
  • Normal: Less than 120/80 mmHg
  • Elevated: 120-129/less than 80 mmHg
  • Hypertension Stage 1: 130-139/80-89 mmHg
  • Hypertension Stage 2: 140 or higher/90 or higher mmHg
  • Hypertensive Crisis: Higher than 180/higher than 120 mmHg
  • Low Blood Pressure: Less than 90/60 mmHg
Factors Affecting Blood Pressure
  • Age: Blood pressure tends to increase with age
  • Family history: High blood pressure tends to run in families
  • Weight: Being overweight or obese increases the risk
  • Physical activity: Lack of physical activity increases the risk
  • Diet: High sodium, low potassium, and excessive alcohol consumption
  • Stress: Chronic stress may contribute to high blood pressure
  • Smoking: Tobacco use increases blood pressure
Measuring Blood Pressure

For accurate readings:

  • Sit with your back straight and supported
  • Keep your feet flat on the floor
  • Support your arm at heart level
  • Rest for 5 minutes before taking a reading
  • Empty your bladder before measuring
  • Avoid caffeine, exercise, and smoking for at least 30 minutes before measurement
  • Take multiple readings and record the results

Introducing the Blood Pressure Calculator

Understanding where you stand can help you take the right steps towards maintaining or improving your Health.

How to Use the Calculator

Using the calculator is simple and user-friendly. Just enter your systolic and diastolic readings in the provided fields. You can also add optional details like your pulse rate, the date and time of the reading, and whether you were sitting, standing, or lying down during the measurement. This information can give you and your doctor a clearer picture of your health.

Understanding Blood Pressure Readings

  • Systolic Pressure: This is the top number, showing the pressure when your heart beats.
  • Diastolic Pressure: This is the bottom number, indicating the pressure when your heart rests between beats.

These two numbers work together to measure your overall blood pressure. Knowing how these values affect your health is crucial for managing blood pressure effectively.
