VORRICHTUNG ZUR IMPEDANZ-KARDIOGRAPHIE |
摘要 |
An impedance cardiograph which determines cardiac output from a measurement of variations of chest impedance, provides an improved method of calculating the effect of patient volume on the measurement from measurable patient height and chest circumference, and provides a correction process that identifies as a source of error variations in the first derivative of impedance. This latter source of error is minimized by preprocessing the impedance derivative value with a compression function which reduces the range of values of the impedance derivative when that value differs significantly from a norm of the population. |
