Why hemodynamic monitoring matters
During anesthesia and intensive care, cardiac output, vascular resistance, and perfusion can change rapidly. Advanced hemodynamic monitoring enables early detection of these changes and supports circulatory stability.
Transpulmonary Cardiac Output with Room Temperature Saline is Accurate and Tracks Directional Changes in Anesthetized Dogs, Cannarozzo P. et al.
This study investigated the measurement of cardiac output using transpulmonary thermodilution in anesthetized dogs. The results showed good accuracy and reliable detection of hemodynamic changes. Trending ability, in particular, proved to be clinically relevant.

Agreement Between Electrical Cardiometry and Pulmonary Artery Thermodilution for Measuring Cardiac Output in Anesthetized Dogs. Paranjape V. et al.
This study compared a non-invasive method for measuring cardiac output (electrical cardiometry) with invasive thermodilution. Although differences in absolute values existed, the method demonstrated a good ability to detect hemodynamic trends. Non-invasive methods can therefore be clinically useful.
