Embodiment Construction

[0032] As mentioned above, the present invention provides for automatic and reliable determination of a subject's baseline for use in standardizing physiological properties obtained from the subject, which overcomes the problems associated with the variable nature of physiological properties due to external factors. existing problems.

[0033] figure 1 A block diagram of an apparatus 100 that can be used to determine a baseline of one or more physiological characteristics of a subject is shown in accordance with an embodiment of the present invention.

[0034]The device 100 comprises a control unit 102 which controls the operation of the device 100 and is capable of implementing the methods described herein. Briefly, the control unit 102 is configured to determine a baseline of one or more physiological properties of the subject based on the detected value of at least one physiological property during the time period in which the subject is in a baseline state (eg, a stable o...

Abstract

There is provided a method and apparatus for determining a baseline for one or more physiological characteristics of a subject. One or more physiological characteristics of a subject and contextual information associated with the subject is acquired. A time period in which the subject is in a baseline state is detected based on the acquired one or more physiological characteristics of the subjectand the acquired contextual information associated with the subject. The baseline for the one or more physiological characteristics of the subject is determined from a value of at least one of the acquired one or more physiological characteristics in the detected time period.

Description

technical field [0001] The present invention relates to the field of measuring and in particular determining a baseline of one or more physiological properties of a subject. Background technique [0002] Quantification of pain and pressure in subjects has been a longstanding clinical need. More recently, for this purpose, physiological characteristics (including vital signs such as heart rate, blood pressure, etc.) have been used to objectify a subject's or patient's response to painful stimuli. The basic underlying mechanism is that painful stimuli are known to activate the autonomic nervous system and have effects on physiological properties. Thus, changes in a subject's pain or stress level can sometimes be determined by observing changes in the subject's physiological characteristics. [0003] Examples of using a subject's physiological characteristics in assessing a patient's physical or emotional state include using electrocardiography (ECG) and photoplethysmography ...
