An apparatus () and method for detecting pulse-related parameters, such as pulse arrhythmia is presented. The apparatus () detects a series of pulses from a user, e.g. through a cuff-related measurement. Time differences, amplitude and pattern differences between multitudes of N pulses are determined. The apparatus investigates the degree of similarity of multiple pulse periods and/or pulse amplitudes and/or pulse pattern and subsequently generates a statistical set of similarity values based on a plurality of compared results. Basing on this, the apparatus generates a decision value based on the statistical sets of similarity values, and uses the decision value to determine whether or not the user discloses a normal pulse rhythm, atrial fibrillation, premature atrial or ventricular contractions, tachycardia, bradycardia and/or unspecified pulse arrhythmia. Further an artefact index is generated, informing the user whether a measurement was taken under sufficient artefact-free measurement conditions.

Detecting apparatus for arrhythmia and detecting method of the detecting apparatus

A blood pressure measuring method, according to which a pulse oscillogram of a patient is defined, the blood pressure is then determined from the pulse oscillogram and displayed. Reliable blood pressure values are obtained without additional cost to the user, by obtaining an evaluation criterion for the presence of haemodynamic stability from the individual pulse oscillogram, the determination of the blood pressure value or the determined blood pressure value being related to the criterion.

Blood pressure measuring method and blood pressure manometer

The method and device serve to measure a proportion of constituents in blood. To this end, electromagnetic radiation of different radiation wavelengths is directed through a tissue () containing blood vessels (). At least a portion of the radiation exiting the vessel is detected using sensors, and a corresponding measured value derived therefrom is fed to an evaluating device. The evaluating device () is connected to at least two sensors () and has an analyzer () for determining a dispersion of radiation by evaluating the intensity of the radiation received by the individual sensors. An individual calibration determination is carried out by evaluating the angle-dependent dispersion and can be drawn upon for conducting a pulse spectroscopic determination of concentrations of substances.

Device and method for measuring constituents in blood

By a method to measure the blood pressure of a patient, a series of measurements for the diastolic, the systolic blood pressure and for the pulse rate are made. The results are analysed in order to determine, and to display whether the patient is properly settled to a rest condition, and whether the patients blood pressure variation is found as being normal. Further it is investigated, whether there are high measurement result alterations due to artefacts. Highly altered results are excluded. If the results are sufficiently similar, an average of the result is made. If the results are not sufficiently similar, but still below pre-defined alteration limits, a weighted average is applied to the systolic and the diastolic blood pressure.

Non-invasive measurement of blood pressure

In a device or in a method for oscillometric measurement of the blood pressure, the pulse time differences are determined associated with the measurement of the blood pressure. Subsequent pulse time differences are stored in a storing unit ( ). A distribution of pulse time differences is calculated in a calculating unit ( ) and compared in a comparing unit ( ) with predetermined reference values. If the distribution or the values of pulse time differences exceed a predetermined amount, an indication means ( ) is activated which indicates existence of arrhythmic activities.

Method and a device for non-invasive measurement of the blood pressure and for detection of arrhythmia

A blood pressure measuring device is operatable in a first operating mode (M ) and in a second operating mode (M ). In the first operating mode, blood pressure values are based on one single measurement. In a second operating mode (M ), a mean value (S , D ) of the systolic and the diastolic blood pressure is calculated on the basis of subsequent measurement values. The blood pressure monitor ( ) is provided with means ( ) for switching between the first operating mode (M ) and the second operating mode (M ).
