Fig. 4From: Noninvasive carbon dioxide monitoring in pediatric patients undergoing laparoscopic surgery: transcutaneous vs. end-tidal techniquesAgreement between PetCO2 and PaCO2 was analyzed using the Bland–Altman method. X-axis: (PetCO2 + PaCO2)/2; Y-axis: PetCO2 – PaCO2. The 95% LOA of PetCO2 – PaCO2 average was –4.4 ± 4.86 mmHg (mean ± 1.96 SD) (n = 128)Back to article page
