How the WHO Indicator Enhances Blood Pressure Monitors for Home Use
Empowering Health Management Through Clear Visual Guidance
With hypertension affecting a growing portion of the global population, personal blood pressure monitoring devices have become an essential part of home healthcare. For device brands, enabling users to quickly interpret their readings is more than just a convenience—it's a design priority. That's why integrating intuitive tools like the WHO Blood Pressure Classification Indicator can enhance both usability and clinical relevance.
Understanding the WHO Blood Pressure Classification
The World Health Organization (WHO) classification is widely accepted as the global standard for categorizing blood pressure levels. At Joytech, we incorporate this system directly into our upper-arm and wrist blood pressure monitors via a color-coded indicator bar on the device display. This intuitive visual cue helps users instantly identify their blood pressure status.
Here's how the classification breaks down:
Category
Systolic (mmHg)
Diastolic (mmHg)
Health Implication
Color Indicator
Optimal
<120
<80
Maintain a healthy lifestyle
Green
Normal
120–129
80–84
Monitor and maintain good habits
Green
High-Normal
130–139
85–89
Borderline—begin regular monitoring
Green
Mild Hypertension
140–159
90–99
Seek medical guidance
Yellow
Moderate Hypertension
160–179
100–109
Medical treatment recommended
Orange
Severe Hypertension
≥180
≥110
Seek immediate medical attention
Red
This design reduces ambiguity, bridging the gap between technical data and user understanding—an important factor when designing devices for both clinical accuracy and home use convenience.
Frequently Asked Questions (FAQ)
Q1: Which reading determines the color level? A: The Blood Pressure Monitor classifies based on the higher of the systolic or diastolic readings. For example, if your systolic pressure is 138 mmHg ("High-normal") and diastolic is 92 mmHg ("Mild Hypertension"), the monitor will display yellow, indicating "Mild Hypertension."
Q2: If the color changes daily, does that mean my blood pressure is unstable? A: Blood pressure naturally fluctuates due to emotions, diet, activity, and time of day. Minor variations are normal. For consistency, measure at the same time daily and focus on long-term trends rather than single readings.
Q3: If the indicator is green, am I completely safe? A: Green means optimal, normal or high-normal blood pressure, but if you have risk factors like family history of heart disease, obesity, or diabetes, regular monitoring and a healthy lifestyle are still recommended.
Q4: Will the color change if my blood pressure differs between morning and evening?
A: Yes, blood pressure follows a daily rhythm. Measure at consistent times and track long-term patterns.
Q5: Can the color indicator replace a doctor’s diagnosis? A: No. The WHO Blood Pressure Indicator is a helpful reference, but it cannot replace professional medical advice. If readings are frequently elevated (yellow or above), consult a doctor.
Q6: Do all blood pressure monitors use the same color system? A: Not necessarily. Some brands use their own classifications, but Joytech follows the WHO standard, ensuring accuracy and global relevance.

The WHO Blood Pressure Classification Indicator isn’t just a medical guideline, but a health management tool. Joytech integrates it into blood pressure monitors, empowering users with clear and meaningful insights every time they measure.
