摘要

A method of and a device for non-invasively measuring the hemodynamic state of a subject or a human patient involving steps and units of non-invasively or minimally invasively measuring cardiac cycle period, mean arterial pressure, stroke volume, diastolic interval and ejection interval and converting the measured mean arterial pressure, stroke volume, diastolic interval and ejection interval into the cardiac parameters such as Preload, Afterload and Contractility, which are the common cardiac parameters used by an anesthesiologist. In the current invention, the use of electrical-mechanical interval has been eliminated for various advantageous reasons.;The converted hemodynamic state of a patient is displayed on a screen as a three-dimensional vector with each of its three coordinates respectively representing Preload, Afterload and Contractility. Therefore, a medical practitioner looks at the screen and - quickly obtains the important and necessary information.
