It looks like your sentence got cut off. If you meant “normal blood pressure values according to medical guidelines,” here they are clearly:
Normal Blood Pressure Values (Adults)
Blood pressure is measured in millimeters of mercury (mmHg) and has two numbers:
- Systolic (top number): pressure when the heart beats
- Diastolic (bottom number): pressure when the heart rests
Standard categories:
1. Normal
- Less than 120 / 80 mmHg
2. Elevated
- 120–129 / less than 80
3. High blood pressure (Stage 1)
- 130–139 / 80–89
4. High blood pressure (Stage 2)
- 140 or higher / 90 or higher
5. Hypertensive crisis (emergency)
- 180 / 120 or higher
- Requires immediate medical attention
Important clarification
- 120/80 is still considered normal, not dangerous
- There is no single “perfect” number for everyone
- Doctors look at trends over time, not one reading
Children and teens
Blood pressure in younger people is not fixed like adults. It depends on:
- Age
- Height
- Sex
Doctors use percentile charts instead of one standard number.
Key takeaway
- Normal adult BP: below 120/80
- Slight increases don’t always mean disease
- Persistent readings above 130/80 may require monitoring
If you want, I can also explain:
- what causes blood pressure to rise suddenly
- or how to measure BP correctly at home (many people get wrong readings without realizing it)
