Embodiment Construction
[0033] As described above, blood pressure measurement devices using 'alternative' blood pressure measurement techniques (i.e. measurement techniques that do not directly measure blood pressure but infer blood pressure from measurements of other physiological properties) must use Line) to measure blood pressure measurement results of blood pressure measurement equipment more directly for calibration. At least two blood pressure measurements / surrogate physiological characteristic measurements from each blood pressure measuring device are required, where those measurements were obtained for different blood pressures, in order to perform the calibration. In order for this calibration to be done within a short length of time (eg only a few minutes, or even within a few breathing cycles), it is necessary to induce changes in the blood pressure in the subject so that measurements at different blood pressures can be obtained.

An apparatus and method for determining a calibration parameter for a blood pressure measurement device. According to an aspect, there is provided an apparatus for determining a calibration parameterfor a first blood pressure, BP, measurement device, the apparatus comprising a control unit that is to be coupled to a first BP measurement device that is for obtaining physiological characteristic measurements of a physiological characteristic of a subject and for determining a blood pressure measurement of the subject from the physiological characteristic measurements, a second BP measurement device that is for obtaining measurements of the blood pressure of the subject and a ventilator that is for providing a controlled flow of gas to the subject.
Description
technical field [0001] The present invention relates to a blood pressure measurement device for obtaining a measurement of a subject's blood pressure, and in particular to an apparatus and method for determining calibration parameters for a blood pressure measurement device. Background technique [0002] In an acute care setting in a hospital, especially in an intensive care unit (ICU) or operating room (OR), a patient's condition may change rapidly and immediate action may be required. One vital sign that can provide an indication of a patient's condition is blood pressure (BP). BP is usually performed with an invasive circuit or with an arm cuff (e.g., automatically by using oscillometric techniques involving the analysis of the magnitude of pressure changes due to blood pulses, or manually by using auscultation techniques involving the detection of Korotkoff sounds). ground) measurement. However, both techniques have significant disadvantages: the invasive circuit carri...
