Pulse-Respiration Quotient (PRQ)
What is Pulse-Respiration Quotient (PRQ)?
Pulse-Respiration Quotient (PRQ) analyzes the relationship between your heart rate and respiratory rate. It provides insights into your metabolic activity and how efficiently your body is using oxygen.

What does it mean to have high Pulse-Respiration Quotient (PRQ)?
A high PRQ may be caused by a significant increase in heart rate without a corresponding rise in respiration rate such as dehydration, fever, caffeine consumption, or response to stress or anxiety.
Both excessively high and low PRQ levels can signal an imbalance or potential health issues.
What does it mean to have low Pulse-Respiration Quotient (PRQ)?
A low PRQ may result from a slower heart rate not paralleled by a decrease in respiratory rate. This is commonly found in well-trained athletes, relaxation, or medications such as beta-blockers that reduce heart rate.
Both excessively high and low PRQ levels can signal an imbalance or potential health issues.
How does Vitals™ SDK measure it?
PRQ is measured by dividing the pulse rate by the respiratory rate.
