1. A vital signs information measuring apparatus comprising:
- a calculating section which calculates a baroreflex index, a sympathetic nerve index, a heart rate, an estimated cardiac output, and an alternative index of blood pressure by using at least one of an electrocardiographic signal of a living body, and a pulse wave of the living body; and
a displaying section that displays changes of the baroreflex index, sympathetic nerve index, heart rate, estimated cardiac output, and the alternative index that are calculated by the calculating section.

12. A vital signs information measuring method comprising:
-
calculating an estimated-cardiac output calculation coefficient by using a cardiac output, electrocardiographic signal, and pulse wave in a resting state of a living body; calculating a baroreflex index, a sympathetic nerve index, a heart rate, and an alternative index of blood pressure by using at least one of an electrocardiographic signal and pulse wave in a load state of the living body, and calculating an estimated cardiac output of the living body by using the electrocardiographic signal and pulse wave in a load state of the living body, and the estimated-cardiac output calculation coefficient; and displaying changes of the baroreflex index, sympathetic nerve index, heart rate, estimated cardiac output, and alternative index of blood pressure which are calculated. - View Dependent Claims (13, 14, 15, 16)
