Implementing transcutaneous CO2 monitoring improves test accuracy and capacity in pulmonary diagnostics.

The research aims to evaluate the effectiveness of transcutaneous CO2 monitoring in estimating arterial PCO2 during cardiopulmonary exercise testing.
Utilized a loaned transcutaneous CO2 monitor for 3 months.
Compared measurements of transcutaneous CO2 to resting arterial blood PCO2 in 18 subjects.
Evaluated clinical significance of measurement differences.
The average difference between PtcCO2 and PaCO2 was 0.3 torr ± 2.0 SD.
Only 1 of 18 subjects exceeded the clinically meaningful difference of 3 torr.
Integration of TCM allowed the lab to increase CPET capacity from 2 to 4 studies per week.

McCurdy et al. (2023) studied this question.
