Some Knowledge about HRV: 
About Pulse Oximeter with integrated HRV analysis. 
Chronic obstructive pulmonary disease (COPD) is characterized by progressive, non-reversible air flow obstruction. Although the smoking is a leading factor in the development of COPD, other factors, such as environmental cannot be excluded. It is well established that in rehabilitation process next to smoking cessation, pharmacological treatment and oxygen therapy, the physical activity plays important role i.e. breathing dynamic mostly. The parameters of heart rate variability (HRV) have demonstrated strong utility in clinical practice and they honestly reflect the activity of autonomic nervous system (ANS). Furthermore, ANS is a good indicator of any disturbance of physiological or psychological homeostasis. 
  
Which Patterns Matter?  
Monitoring your HRV can help you reach peak productivity, manage stress, and fine-tune your training regimen.
A single nightly HRV reading can show you:
A higher HRV score that reflects a rest day, cool bedroom, or “mindful” low/moderate intensity activities such as hiking or yoga
A lower HRV score that results from dehydration, alcohol, late meal or exercise, illness, a high-intensity workout, acute stress, or a hot bedroom.
