Embodiment Construction
[0049] As described above, the present invention provides a method for determining whether a blood pressure measurement is reliable (i.e., whether a blood pressure measurement is a reliable indicator of a subject's long-term blood pressure or whether a blood pressure measurement has been made before, during, or subsequently affected by the subject's pain and / or stress level).
[0050] figure 1 A block diagram of a device 2 that can be used to assess the reliability of measurements of blood pressure according to an embodiment of the invention is shown. As described below, in some embodiments device 2 is, or part of, a device that measures a subject's blood pressure, and in other embodiments device 2 may be separate from the device or apparatus used to measure a subject's blood pressure. In those embodiments, the measurement of blood pressure may be obtained by a separate device and provided to the device 2 either automatically (eg electronically via a wired or wireless connect...

There is provided a method of assessing the reliability of a measurement of blood pressure of a subject, the method in a control unit of an apparatus comprising obtaining a first measurement of at least one physiological characteristic of the subject that is indicative of the level of pain and / or stress of the subject, wherein the first measurement is made prior to a measurement of blood pressurebeing made; obtaining the measurement of blood pressure of the subject; obtaining a second measurement of the at least one physiological characteristic of the subject, wherein the second measurement is made after the measurement of blood pressure is made and prior to a subsequent measurement of blood pressure being made; and determining if the measurement of blood pressure is reliable based on thefirst measurement and the second measurement, wherein the measurement of blood pressure is determined to be reliable if the first measurement and the second measurement indicate a low level of pain and / or stress. A corresponding apparatus that implements the method is also provided.
Description
technical field [0001] The present invention relates to the field of measurement of blood pressure of a subject, and in particular to a method of assessing the reliability of a blood pressure measurement and a device for carrying out the method. Background technique [0002] Non-invasive arterial blood pressure (NIBP) is typically measured by slowly varying the pressure in a cuff wrapped around a subject's upper arm. NIBP works by measuring sounds away from the cuff (known as the auscultation method, based on Korotkoff sounds) or by measuring pressure pulsations in the cuff caused by volume pulsations in the arm and brachial arteries and extracting features from the envelope of these pressure pulses (known as arterial pulsation method) to determine. Arteriography methods are easily automated and widely used. However, the auscultatory method is the "gold standard" for cuff-based NIBP measurements. [0003] A subject's blood pressure (BP) is a dynamic value and is easily af...
