CALIBRATION METHOD AND ARRANGEMENT AND SENSOR FOR NON-INVASIVELY MEASURING BLOOD CHARACTERISTICS OF A SUBJECT

摘要

A calibration method for an apparatus for non-invasively monitoring blood characteristics of a subject is disclosed. The apparatus is provided with a computational model representing a relationship between in-vivo measurement signals obtained from the subject and the blood characteristics. The providing includes employing at least one tissue property variable in the computational model, in which the at least one tissue property variable is indicative of absorption and scattering characteristics of the subject's tissue. An arrangement for determining blood characteristics of a subject and a sensor for the arrangement are also disclosed.
