I'd like to get a better understanding of what the normal/typical range is for:
- Heart Rate Variability;
- Sleeping heart rate range for percentage above and below resting heart rate;
- Percentage of tossing and turning;
- High and low limits for estimated oxygen variation.
If age is a factor, I am a 75-year old male but also interested in other age ranges.
Thank you for any comments/clarifications you can provide.
