Comparison of prolonged exhalation end-tidal CO₂ and transcutaneous CO₂ monitoring in COPD patients.

ABSTRACT:

Background

Noninvasive evaluation of partial pressure of carbon dioxide (PCO₂) is clinically important for screening and monitoring of hypercapnia, especially in patients with chronic obstructive pulmonary disease (COPD). However, the comparative accuracy of end-tidal PCO₂ (PetCO₂) and transcutaneous PCO₂ (PtcCO₂) monitoring in COPD remains uncertain. This study aimed to evaluate the agreement between PetCO₂ obtained by using modified method of prolonged expiration with an integrated calculation algorithm (PetCO₂-PA) and PtcCO₂ with arterial PCO₂ (PaCO₂) in patients with COPD.

Methods

In this single-center study, 83 patients with COPD (48 at stable phase and 35 durin
