Does an adjusted calibration of a heated transcutaneous CO2 electrode accurately reflect arterial CO2 in infants and children?
Adjusting the calibration of a heated transcutaneous CO2 electrode by dividing the reading by 1.61 allows it to reliably predict arterial CO2 in pediatric patients.
Monaco et al. (1983) studied this question.
