Transcutaneous carbon dioxide (PtcCO2) monitoring is a non-invasive method increasingly being used to assess acute respiratory failure (ARF).However there are conflicting findings when evaluating high levels of PaCO2. The aim of our study is to evaluate the accuracy of this method in ARF patients according to the severity of hypercapnia. Method: prospective study including patients with ARF admitted in a RICU, who required arterial blood gas (ABG) analysis. Simultaneously, PtcCO2 was measured (SenTec digital monitor). Data: patients demographics, diagnosis, ABG and PtcCO2. Data are presented as mean ± SD. Relations between PaCO2 and PtcCO2 were assessed by Pearson correlation coefficient and the intraclass correlation coefficient (ICC). Bland-Altman analysis was used to test data dispersion. ANOVA test was used for comparing the difference of PaCO2 and PtcCO2, in different levels of PaCO2: level 1 60 mmHg. Results: 74 patients, mean age 66 ± 11 years. Most frequent diagnosis was AECOPD (40%). Mean PaCO2 was 58 ± 11 and mean PtcCO2 was 54 ± 10 mmHg. Correlations between PaCO2 and PtcCO2 was r =0,92 (p Conclusions: our study showed good agreement of PtcCO2 monitoring with ABG. However, we have to take into account two aspects: PtcCO2 undervalues PaCO2 levels and PtcCO2 is less reliable in patients with sever hypercapnia.

Transcutaneous carbon dioxide (PtcCO2 ) monitoring is being used increasingly to assess acute respiratory failure. However, there are conflicting findings concerning its reliability when evaluating patients with high levels of PaCO2 . Our study evaluates the accuracy of this method in subjects with respiratory failure according to the severity of hypercapnia. We included subjects with respiratory failure, admitted to a respiratory intermediate care unit, who required arterial blood gas analysis. Simultaneously, PtcCO2 was measured using a digital monitor. Relations between PaCO2 and PtcCO2 were assessed by the Pearson correlation coefficient. Bland-Altman analysis was used to test data dispersion, and an analysis of variance test was used to compare the differences between PaCO2 and the corresponding PtcCO2 at different levels (level 1, <50 mm Hg; level 2, 50-60 mm Hg; level 3, >60 mm Hg). Eighty-one subjects were analyzed. The main diagnosis was COPD exacerbation (45%). PtcCO...
