Fig. 3From: Noninvasive carbon dioxide monitoring in pediatric patients undergoing laparoscopic surgery: transcutaneous vs. end-tidal techniquesAgreement between PtcCO2 and PaCO2 was analyzed using the Bland–Altman method. X-axis: (PtcCO2 + PaCO2)/2; Y-axis: PtcCO2 – PaCO2. The 95% LOA of PtcCO2 – PaCO2 average was 0.66 ± 4.92 mmHg (mean ± 1.96 SD) (n = 128)Back to article page
