C.O./CCO Curve Alert Messages
After each measurement trial, the monitor analyzes the thermodilution curve. If the curve appears
abnormal, a curve alert message appears in the procedure window. A question mark symbol ("
?") may
appear next to the cardiac output numeric if any of these messages appear. The curve alert messages
are not error messages and do not necessarily mean that the measured values are invalid.
