In today’s fast-paced world, accurate and early health assessment is more important than ever. Nidan, an AI-powered diagnostic tool, brings advanced healthcare to your fingertips. In just 60 seconds, using a smartphone camera, Nidan provides 25+ vital parameters—completely non-invasively.
Here’s a breakdown of what Nidan measures and how each metric supports smarter diagnosis and better care.
🔹 Key Body Vitals
1. Heart Rate
Heart rate indicates how efficiently your heart is working. Abnormalities may point to underlying cardiac conditions, stress, or dehydration.
2. Respiration Rate
This measures the number of breaths per minute. It’s a key indicator of respiratory function and can help detect conditions like asthma or anxiety.
3. Oxygen Saturation (SpO₂)
SpO₂ shows how much oxygen your red blood cells are carrying. Low oxygen levels may indicate lung or cardiac issues, and are critical in emergency triage.
4. Blood Pressure (Systolic & Diastolic)
Monitoring both systolic and diastolic BP helps identify hypertension or hypotension, both of which impact heart and brain health.
🔹 Cardiac Health Metrics
5. SDNN (Standard Deviation of NN intervals)
A Hear Rate Variability (HRV) parameter that reflects overall heart health. Lower values may indicate stress, fatigue, or underlying disease.
6. RMSSD (Root Mean Square of Successive Differences)
RMSSD is used to assess parasympathetic nervous activity and is vital in monitoring recovery, resilience, and fitness levels.
7. PNN50
This measures the percentage of consecutive heartbeats that differ by more than 50 ms. It reflects heart rhythm stability and autonomic balance.
8. Cardiac Output
The amount of blood the heart pumps per minute—essential for evaluating heart performance.
9. Mean Arterial Pressure (MAP)
An average blood pressure reading that reflects the true perfusion pressure to vital organs.
10. Heart Utilised
This indicates how close a person is operating to their maximum heart rate—a key fitness and fatigue metric.
11. Heart Rate Max
The estimated maximum number of beats per minute your heart should reach during exercise.
12. Heart Rate Reserve
The difference between resting heart rate and maximum heart rate, often used in exercise prescription.
13. Target Heart Rate Range
This personalized range helps identify safe and effective intensity levels for physical activity.
14. VO₂ Max
VO₂ Max measures the maximum oxygen your body can utilize during exercise. It’s a powerful indicator of cardiovascular endurance.
🔹 Physiological Indicators
15. Body Mass Index (BMI)
A standard marker for weight categories that can indicate risk for obesity-related diseases.
16. Blood Volume
Represents the total volume of blood circulating in the body. It can indicate hydration levels and cardiovascular efficiency.
17. Total Body Water
Shows the percentage of water content in your body, helping evaluate hydration and overall cell function.
18. Body Water %
A refined breakdown of water distribution, helpful in assessing metabolic performance and fitness.
19. Total Body Fat
Reflects fat mass, important for assessing obesity risk, hormonal balance, and lifestyle changes.
20. Body Weight
A basic yet essential metric in monitoring trends in overall health, especially when viewed with BMI and body fat.
🔹 Stress & Autonomic Nervous System (ANS)
21. Stress Level (SL)
Derived from HRV analysis, this score reflects acute stress on the body—both physical and emotional.
22. Stress Index (SI)
This provides a numeric scale of how efficiently your body is managing stress and returning to balance.
23. ANS Interaction
A composite reading of how well your autonomic nervous system is functioning—critical for maintaining homeostasis.
🔹 Blood Biomarkers
24. HbA1c (Predicted)
An estimate of your average blood sugar level over the past 3 months. Useful in tracking diabetes and prediabetic conditions.
25. Diabetes Control Score (DCS)
This unique score reflects how well a person is managing their blood glucose, offering insights for early intervention and treatment plans.
