The invention provides a seismocardiograph system, which includes an accelerometer, adapted to obtain accelerometer data from user, and a bandpass filter, adapted to filter the accelerometer data. The system further includes an envelope filter, adapted to suppress S2 peaks in the band pass filtered accelerometer data, wherein the envelope filter comprises: a low-pass filter; and a comb filter, wherein the delay of the comb filter is tuned to a left ventricle ejection time (LVET).

The present invention relates to a processing device for processing accelerometer signals (-) for use in monitoring vital signs of a subject, comprising&#x2014;a signal input unit () for inputting an accelerometer signal (-) of the subject in time, the accelerometer signal (-) being related to at least one physiological event being a cardiovascular or a respiratory event of the subject and measured for at least one spatial direction, an envelope determination unit () for determining an envelope signal () of the input accelerometer signal (-), a calculation unit () for calculating an adjustment factor () based on an estimated time interval () between a first and a second physiological event of the subject, and a signal adjustment unit () for adjusting the determined envelope signal () by multiplying the envelope signal () with the calculated adjustment factor ().

Processing device, system and method for processing accelerometer signals for use in monitoring vital signs of a subject

A method, and corresponding system (), for monitoring patients based on activity state and posture. Activity state and/or posture of a patient are measured. Further, one or more vital signs of the patient are measured according to a schedule. Based on the measured activity state and/or posture of the patient and the measured one or more vital signs, the schedule is adjusted and/or patient deterioration is monitored for.

Patient monitoring for sub-acute patients based on activity state and posture

A medical device (), medical method and graphical user interface (GUI) () displaying data regarding measurement of a physiological parameter. A window () for the physiological parameter is displayed using a display device (). The window () includes an indicator () identifying a measured value of the physiological parameter. In response to automatic trigger of measurement of the physiological parameter, the window () is updated to further include a first indicator () indicating measurement of the physiological parameter is ongoing. In response to manual trigger of measurement of the physiological parameter, the window () is updated to replace the indicator () identifying the measured value with a second indicator () indicating measurement of the physiological parameter is ongoing. The second indicator () is prominent relative to the first indicator ().
