Vyvo Smart App: How does the Health Index work?

Vitals (Max Score: 35) 

Assesses cardiovascular, respiratory, and overall health through factors like heart rate, blood pressure, ECG, and SpO2 levels.

The Vitals category carries a total weight of 35% in the Health Index and is based on three subcategories:

Cardiovascular Analysis (40%):

• Heart Rate (17%): Graded based on the user’s average heart rate.
• Blood Pressure (13%): Graded based on the user’s average blood pressure.
• ElectroCardiogram (ECG) (25%): Only AI-analyzed ECG readings considered, with expected result being “Normal”. Any abnormal reading will result in negative points for this factor.
• Accelerated Photoplethysmograph (APG) (20%): Readings over 3 are considered risky and end up in negative points, there is a 10% tolerance.
• Atrial Fibrillation (AFib) (25%): Calculated based on AFib measurement, with expected results being “Normal”. Abnormal results will cause negative points, there is a 20% tolerance.

Respiratory Analysis (40%): 

• Breath Rate (30%): Graded based on the user’s average breath rate within the time period.
• Blood Oxygen Saturation (SpO2) (70%): Each result is evaluated individually, with readings over 94 considered normal, there is a 10% tolerance. 

Overall Analysis (20%):

• Body Mass Index (50%): Expected to be in healthy zone.
• Temperature (50%): Graded based on average of the user within the time period. 

Activity (Max Score: 30)

The Activity category contributes 30% to the Health Index.

It evaluates weekly sports participation, daily steps, and average calories burned. If you don't reach the goal you will not receive score for the subcategory.

Subcategories and Weights:

• Daily Steps (50%): Users are expected to take at least 6000 steps, five times a week. If the goal is missed, points will be deducted from total. 
• Weekly Sports (30%): Users are expected to do sport activities for at least 30 minutes, twice a week. If the goal is missed, points will be deducted from total.
• Average Calories Burned (20%): Users are expected to burn at least 300 calories to match the goal.

Well-being (Max Score: 35)

Includes sleep duration and quality, stress levels, energy levels, stand hours, and bioelectrical impedance analysis (BIA).

The Well-being category has a weight of 35% in the Health Index.

Subcategories and Weights:

• Sleep Duration Analysis (20%): Expected to be over 7 hours for adults.
• Sleep Quality Analysis (20%): Users are expected to have over 70% score for at least 4 days of the week.
• Stress Analysis (20%): Expected to maintain a stress level lower than 70, there is a 10% tolerance. 
• Stand Hours (20%): Users should stand at least once at 10 different hours of the day, five days a week.
• Energy Analysis (10%): Users should maintain a 50 energy level for at least two-thirds of the day.
• Bioelectrical Impedance Analysis (BIA) (10%):This evaluates various parameters such as Total Body Water, Intracellular Water, Extracellular Water, Sodium/Potassium Ratio, Extracellular Mass, and Body Cell Mass.
