Excerpt

Sir: The accuracy of the PiCCO (Pulsion Medical Systems) pulse contour (PC) cardiac output (CO) method is known to be affected by marked changes in vascular tone. However, the need for recalibration, using transpulmonary thermodilution (TDtp), of the PC method has not been studied under stable clinical conditions. Therefore we assessed the degree of drift in the PC method over varying time intervals in patients who were in sinus rhythm and not receiving a vasoactive or inotropic drug infusion. …
