Objective: To determine the accuracy and clinical utility of a continuous arterial blood gas (ABG) monitor during lung transplantation. Design: Prospective, observational cohort study. Setting: University hospital. Participants: Eleven patients undergoing bilateral sequential lung transplantation (BSLTx). Interventions: Repeated ABG sampling. Measurements and Main Results: Agreement was measured by the bias (limits of agreement): pH, 0.006 (-0.10 to 0.10); PaO2, -22 mmHg (-130 to 86 mmHg); and PaCO2, - 1.6 mmHg (-13.4 to 10.2 mmHg). Sensitivity and specificity of the Paratrend 7 (Biomedical Sensors, Ltd, Malvern, PA) PaO2 measurements (to detect PaO2 < 100 mmHg) were 84.6% and 97.6%, respectively. Conclusion: Continuous ABG monitoring with the Paratrend 7 shows sufficiently good agreement with laboratory blood gas analysis during BSLTx and thus is a convenient alternative to intermittent laboratory blood gas measurement. Because of the potential for significant (and sometimes rapid) acid-base disturbances, continuous ABG monitoring may have a role during most lung transplantation procedures.
