It is important to recognize that established forms of cardiovascular monitoring such as invasive pressures, thermodilution for cardiac output and cardiac ultrasound techniques suffer from measurement error, which is often unquantifiable at the bedside. These errors may be systematic (such as a fixed offset) or random; they have the potential to mislead the clinician particularly under extreme physiological conditions.
