Blood Pressure Value Parsing

Recognize format: XXX/YY or XXX YY

• Systolic: First value
• Diastolic: Second value

Measurement Time Keywords

Measurement Position Keywords

Measurement Arm Keywords

Target Organ Assessment Keywords

Heart Assessment

Kidney Assessment

Retina Assessment

Step 2: Check Information Completeness

BP Record Required:

• Systolic (mmHg)
• Diastolic (mmHg)

Target Organ Assessment Required:

• Assessment type
• Assessment result

Cardiovascular Risk Assessment Needs:

• Age
• Gender
• Systolic BP
• Smoking status
• Diabetes status
• Total cholesterol
• HDL cholesterol
• Antihypertensive treatment status

Step 3: Interactive Prompts (If Needed)

Scenario A: Incomplete BP Values

Please provide complete BP reading, format: systolic/diastolic
Example: 135/85

Scenario B: Additional Information Inquiry

Please supplement the following information (optional):
- Heart rate (pulse XX)
- Measurement time (morning/evening)
- Measurement position (sitting/standing/lying)
- Measurement arm (left/right)

Scenario C: Missing Target Organ Assessment Parameters

Please provide assessment results:
- Echocardiogram: normal/abnormal/lvh
- ECG: normal/abnormal
- Urine microalbumin (UACR): value (mg/g)
- eGFR: value (ml/min/1.73m²)
- Retina grade: grade_0-4

Step 4: Generate JSON

Step 5: Save Data

1. Read data/hypertension-tracker.json
2. Update corresponding sections based on operation type
3. Update statistics
4. Write back to file

Execution Instructions

1. Identify operation type (record/trend/average/history/status/risk/target/heart/kidney/retina/medication)
2. Extract parameter information
3. Check required field completeness
4. If missing, ask user to supplement
5. Generate JSON compliant with schema.json
6. Save to data/hypertension-tracker.json
7. Output confirmation and medical recommendations

Example Interactions

Example 1: Record Blood Pressure

User: record 135/85 pulse 78

AI: Blood pressure measurement recorded
Time: 2025-01-02 08:00
Systolic: 135 mmHg
Diastolic: 85 mmHg
Pulse: 78 bpm
Classification: High-normal

Target: <130/80 mmHg
Status: Not on target (elevated systolic)

Recommendation: Reduce sodium intake, exercise regularly, monitor regularly

Example 2: View Blood Pressure Trend

User: trend

AI: Blood pressure trend analysis (past 7 days)
━━━━━━━━━━━━━━━━━━━━━━━━━━
Average BP: 132/83 mmHg
Morning average: 135/85 mmHg
Evening average: 128/80 mmHg

Circadian rhythm: Dipper (normal)
Achievement rate: 71.4%

Trend: BP control stable, morning BP slightly elevated

Recommendation: Continue monitoring, pay attention to morning BP control

Example 3: Cardiovascular Risk Assessment

User: risk

AI: Cardiovascular Risk Assessment
━━━━━━━━━━━━━━━━━━━━━━━━━━
10-year ASCVD risk: 12.5%
Risk level: High

Major risk factors:
- Hypertension (currently poorly controlled)
- Age >55
- Elevated total cholesterol

Recommendations:
1. Strict BP control to target
2. Consider statin therapy
3. Low-salt diet, regular exercise
4. Quit smoking, limit alcohol

Recommendation: Seek medical attention soon, consult doctor for treatment adjustment

Example 4: View Achievement Status

User: status

AI: Blood Pressure Achievement Report
━━━━━━━━━━━━━━━━━━━━━━━━━━
BP Target: <130/80 mmHg

Past 7 days:
- Average BP: 132/83 mmHg
- Days on target: 5/7 (71.4%)
- Achievement rate: 71.4%

Past 30 days:
- Average BP: 128/81 mmHg
- Days on target: 22/30 (73.3%)
- Achievement rate: 73.3%

Control Evaluation: BP control approaching target, keep working
