Vital Monitor — Your Personal Vital Signs Guardian

Specialized skill for comprehensive vital signs tracking, trend analysis, and early warning detection. I help you monitor your body's key indicators and catch concerning changes early.

What I Monitor

Core Vital Signs

• Blood Pressure (Systolic/Diastolic) — Cardiovascular health
• Heart Rate (Pulse) — Heart rhythm and fitness
• Body Temperature — Infection and metabolic status
• Respiratory Rate — Lung function (when provided)
• Oxygen Saturation (SpO2) — Blood oxygen levels
• Weight & BMI — Metabolic health indicator

Derived Metrics

• Pulse Pressure (Systolic - Diastolic)
• Mean Arterial Pressure (MAP)
• BMI Classification
• Heart Rate Variability trends

Universal Reference Standards

I adapt reference ranges based on your region and demographics:

Blood Pressure Classification (ACC/AHA 2017 — Used Globally)

Category	Systolic (mmHg)	Diastolic (mmHg)	Action
Normal	<120	<80	Maintain
Elevated	120-129	<80	Lifestyle changes
Stage 1 Hypertension	130-139	80-89	Lifestyle + possible medication
Stage 2 Hypertension	≥140	≥90	Medication + lifestyle
Hypertensive Crisis	≥180	≥120	Emergency care

Note: Some regions use slightly different cutoffs (e.g., Europe: 140/90 for hypertension). I adapt to your location.

Heart Rate Targets (Resting)

Population	Normal Range	Athlete Range
Adults	60-100 bpm	40-60 bpm
Children (6-12)	70-110 bpm	—
Elderly (>65)	60-100 bpm	50-70 bpm

Body Temperature

Site	Normal Range	Fever Threshold
Oral	36.1-37.2°C (97-99°F)	≥38.0°C (100.4°F)
Rectal	36.5-37.7°C	≥38.0°C
Axillary	35.9-36.7°C	≥37.5°C
Tympanic	35.8-37.2°C	≥38.0°C

BMI Classification (WHO Standard)

Classification	BMI (kg/m²)	Health Risk
Underweight	<18.5	Moderate
Normal	18.5-24.9	Low
Overweight	25.0-29.9	Moderate
Obese Class I	30.0-34.9	High
Obese Class II	35.0-39.9	Very High
Obese Class III	≥40.0	Extremely High

Note: Asian populations often use lower cutoffs (Overweight ≥23, Obese ≥25) due to different metabolic risk profiles.

Analysis Capabilities

1. Trend Analysis

Linear Trend Detection:

BP Trend over 30 days:
Week 1: 138/88 → Week 2: 135/85 → Week 3: 132/82 → Week 4: 130/80
Trend: ↓ Improving (-8/-8 mmHg)
Significance: Statistically significant improvement

Variability Assessment:

BP Variability (CV = Coefficient of Variation):
CV = 8.2% (Target: <10% for stability)
Status: Good control consistency

2. Time-of-Day Patterns

Morning Surge Detection:

Morning BP (6-10 AM): 142/88
Evening BP (6-10 PM): 128/78
Morning surge: +14/+10 mmHg
Risk: Elevated morning surge associated with CV events
Recommendation: Take BP medication at bedtime

3. Classification Tracking

BP Classification History:
Jan: Stage 2 (148/92)
Feb: Stage 1 (138/86) ← Started medication
Mar: Stage 1 (132/84)
Apr: Elevated (128/82) ← Lifestyle changes
Status: ↓↓ Significant improvement

Early Warning System

🚨 Critical Alerts (Immediate Medical Attention)

Vital Sign	Critical Threshold	Response
BP	≥180/110 mmHg	Call emergency services
BP	<90/60 mmHg with symptoms	Seek urgent care
Heart Rate	>120 bpm at rest	Seek urgent care
Heart Rate	<50 bpm with symptoms	Seek urgent care
Temperature	≥39.5°C (103.1°F)	Seek medical care
SpO2	<92%	Seek urgent care

⚠️ Attention Alerts (Schedule Appointment)

Pattern	Threshold	Action
BP Trend	Rising >5 mmHg/week	Schedule doctor visit
Weight	Gain >1 kg (2.2 lb) in 3 days	Check for fluid retention
BP	Consistently >160/100 for 5+ days	Medication adjustment needed
HR	Irregular rhythm detected	Cardiology consultation

Risk Stratification

Cardiovascular Risk Score (Simplified)

Risk Factors:
- BP ≥140/90: +3 points
- BP 130-139/80-89: +2 points
- Age >55 (men) or >65 (women): +2 points
- BMI ≥30: +2 points
- Current smoker: +3 points
- Diabetes: +3 points
- Family history of premature CVD: +1 point

Total Risk:
0-2: Low risk
3-5: Moderate risk
6-9: High risk
≥10: Very high risk

Measurement Best Practices

Blood Pressure Measurement Protocol

Before Measuring:

1. Rest 5 minutes in seated position
2. Avoid caffeine, exercise, smoking for 30 minutes
3. Empty bladder
4. Sit with back supported, feet flat on floor
5. Arm supported at heart level

During Measurement:

1. Don't talk
2. Use correct cuff size (bladder encircles 80% of arm)
3. Take 2 readings, 1 minute apart
4. Record the average

Home Monitoring Schedule:

• New diagnosis: Twice daily (morning + evening) for 7 days
• Stable hypertension: 3-4 times per week
• Medication change: Daily for 2 weeks
• General monitoring: Weekly

Weight Measurement Protocol

1. Same time each day (morning, after bathroom, before eating)
2. Same scale
3. Light clothing or no clothing
4. Record weekly average (daily weights fluctuate)
