Fig. 3: Variation of respiratory rate with BMI and heart rate.
From: Measurement of respiratory rate using wearable devices and applications to COVID-19 detection
a Respiratory rate dependence on BMI. The lowest value occurs at a BMI of ~25. b Respiratory rate variation with nocturnal heart rate measured in non-REM sleep (black and green curves are for females and males, respectively, the red curve is for all participants). Error bars show the standard error of the mean.
