Why the study?
Noninvasive methods for accurate physiological dead space (VD/VT) assessment during exercise in patients with COPD are lacking.
Does transcutaneous PCO2 accurately estimate arterial PCO2 and physiological dead space fraction during exercise in COPD patients?
Population
10 COPD patients
Comparison
TcPCO2 vs PaCO2, end-tidal CO2, and the Jones equation
Design
Comparative physiological study during incremental exercise

TcPCO2 may enable accurate noninvasive VD/VT estimation during exercise in COPD; leaves open prospective validation before clinical adoption.
Does transcutaneous PCO2 accurately estimate arterial PCO2 and physiological dead space fraction during exercise in COPD patients?
Transcutaneous PCO2 provides an accurate, noninvasive alternative to arterial blood gas for estimating arterial PCO2 and physiological dead space fraction during rest and exercise in COPD patients.
