PiCCO limitations Atrial or ventricular arrhythmia: you need a stable pulse to measure the contour of Intra-Aortic Balloon pump: once again, the pulse contour is all wrong; but you can still get thermodilution cardiac output measurements. Aortic aneurysm: the contour will be bizarre because the arterial compliance is going to be weird, with the aortic aneurysm acting as a damping system by absorbing all the pressure wave. Extracorporeal circuit: when you are on bypass, there is no real arterial waveform Pneumonectomy: PiCCO relies on there being a relatively normal pulmonary vasculature Massive pulmonary embolism: as above; it is essentially a pneumonectomy by embolism. Intracardiac shunt: the PA catheter will also give an inaccurate thermodilution reading www.derangedphysiology.com
