Key result
Uncalibrated pulse contour systems offer less-invasive cardiac output monitoring but demonstrate limited accuracy compared to thermodilution in critically ill patients with altered systemic vascular resistance.

Limits adoption of uncalibrated pulse contour CO monitoring in shock; leaves open validation of calibrated alternatives in altered SVR.
Do uncalibrated pulse contour systems accurately estimate cardiac output compared to reference methods in critically ill patients?
Uncalibrated pulse contour systems provide less-invasive cardiac output monitoring but lack sufficient accuracy in critically ill patients with altered vascular resistance, requiring careful patient selection and waveform quality verification.
Jörn Grensemann (2018) conducted a review in Critically ill patients requiring hemodynamic monitoring. Uncalibrated pulse contour systems (PCS) vs. Thermodilution or other reference methods was evaluated. Uncalibrated pulse contour systems offer less-invasive cardiac output monitoring but demonstrate limited accuracy compared to thermodilution in critically ill patients with altered systemic vascular resistance.
