Smart algorithms have recently been developed for the automatic detection and correction of abnormal arterial pressure waveform damping, which can significantly impact hemodynamic measurements.
Abnormal damping in arterial pressure monitoring can lead to inaccurate hemodynamic measurements, and new smart algorithms offer a promising solution for automatic detection and correction.
Both over and underdamping of the arterial pressure waveform are frequent during continuous invasive radial pressure monitoring. They may influence systolic blood pressure measurements and the accuracy of cardiac output monitoring with pulse wave analysis techniques. It is therefore recommended to regularly perform fast flush tests to unmask abnormal damping. Smart algorithms have recently been developed for the automatic detection of abnormal damping. In case of overdamping, air bubbles, kinking, and partial obstruction of the arterial catheter should be suspected and eliminated. In the case of underdamping, resonance filters may be necessary to normalize the arterial pressure waveform and ensure accurate hemodynamic measurements.
