Embodiment Construction

[0019] figure 1 One embodiment of a monitoring device / system 10 for monitoring a subject 100 is illustrated. The monitoring device / system generally acquires a plurality of physiological signals 101 from the subject, wherein one physiological signal corresponds to one measurement channel. These physiological signals may typically include several types of signals, such as ECG, EEG, blood pressure, respiration and plethysmographic signals, among others. Based on the raw real-time physiological signal data obtained from the subject, a number of physiological parameters can be determined. Physiological parameters here refer to variables calculated from waveform data of one or more channel signals acquired from the subject. Although the physiological parameter is typically a discrete parameter derived from one or more measurement channels, the physiological parameter may also represent a waveform signal value determined during a predetermined period of time. Each signal parameter...

Abstract

A method, apparatus and computer program product are disclosed for non-invasively determining blood pressure of a subject. To improve the specificity of automatic blood pressure determinations in a patient monitor provided with a non-invasive blood pressure determination unit, a physiological index indicative of sympathetic activity is derived from a subject, variations in the physiological index are monitored, and the blood pressure determination unit is instructed to initiate blood pressure determination when the variations fulfill a predetermined condition.

Description

technical field [0001] The present disclosure generally relates to automatic activation of non-invasive blood pressure measurements. Background technique [0002] Blood pressure measurement can be divided into non-invasive and invasive measurement methods. Invasive blood pressure measurement is performed with an endovascular catheter by placing a cannula needle in the artery. Invasive measurements can be used when continuous tracking of blood pressure is required and when accurate information about the waveform of blood pressure is required. However, invasive blood pressure measurement has some inherent disadvantages, including risk of infection, thrombosis, damage to vessel walls, and bleeding. Therefore, patients with invasive blood pressure monitoring require more work and supervision than patients who do not require invasive measurements. In addition, non-invasive measurements are simpler to perform and require less training for caregivers. Therefore, invasive measur...
