Abstract

Objective: To explore the accuracy of a continuous transcutaneous CO2 (TCCO2) monitor, used in an intermittent rather than a continuous fashion, to obtain quick (<5 mins) CO2 readings. Design: Prospective study. Setting: An urban pediatric intensive care unit in a university teaching hospital. Patients: A convenience sample of pediatric patients with indwelling arterial catheters. Intervention: Transcutaneous monitoring was done simultaneous with arterial blood gas monitoring. Measurements and Main Results: There were 49 simultaneous-readings on 19 patients, age 5 days to 16 years, with 13 different diagnoses. The TCCO2 was related to the PCO2 by a Pearson product coefficient of 0.79 (p < .0005), with a mean difference of 1.94 (TCCO2 > PCO2) and 95% confidence interval of -0.12 to 4.07. The scatterplot produces a regression line characterized by the following equation: PCO2 = (TCCO2 x 1.05) - 4.08. Conclusions: Further study to evaluate intermittent TCCO2 as a practical clinical variable is warranted. This study should encourage refinement of the technology to be more accurate for this use.
