Editor—We read with great interest the study by Compton and colleagues1 comparing minimal invasive measurements of cardiac output obtained with two devices, the PiCCOTM and the FloTracTM/VigileoTM system. The latter has been introduced into clinical practice in 2005, and early studies comparing this device with established methods to determine cardiac output have shown limited agreement only. As a consequence, the algorithm for calculating stroke volume, heart rate, and hence cardiac output derived from the arterial pressure
