RR - CV
percentage
Coefficient of variation for respiratory rate: measures how consistently the rate that you breath across days.
Typical optimal range 0 - 5
Population median 4
Key factors
- Seasonal allergies and respiratory health
- Environmental air quality
- Hydration levels
What affects this metric
- Illness is the most common cause of a sudden rise in variability.
- Alcohol and altitude both disturb breathing consistency.
- Allergies and nasal congestion change night-to-night patterns.
