摘要： The invention relates to prediction of a rapid symptomatic drop in a subject's blood pressure, e.g. during a medical treatment or when operating an aircraft. To this aim, a pulse shape parameter (Pps) with respect to a peripheral body part (105) of the subject (P) is registered by means of a pulse oximetry instrument (110) adapted to detect light response variations in blood vessels. An initial pulse magnitude measure is calculated based on a pulse shape parameter (Pps) received at a first instance. During a measurement period subsequent to the first instance, a respective pulse magnitude measure is calculated based on each of a number of received pulse shape parameters (Pps). It is further investigated, for each pulse magnitude measure in the measurement period, whether or not the measure fulfills a decision criterion relative to the initial pulse magnitude measure. An alarm triggering signal (α) is generated if the decision criterion is found to be fulfilled.

摘要： A method of monitoring the integrity of a fluid connection between first and second fluid containing systems based on at least one time-dependent measurement signal from a pressure sensor in the first fluid containing system. The pressure sensor detects first pulses originating from a first pulse generator in the first fluid containing system and second pulses originating from a second pulse generator in the second fluid containing system. A parameter value representing a distribution of signal values within a time window is calculated by analyzing the measurement signal in the time domain and/or by using information on the timing of the second pulses in the measurement signal. The parameter value may be calculated as a statistical dispersion measure of the signal values, or from matching the signal to a predicted temporal signal profile of the second pulse. The integrity of the fluid connection is determined from the parameter value.

摘要： A monitoring arrangement 100 is configured to predict a rapid syruptomatic drop in a subject's blood pressure, e.g. during a medical treatment or when operating aircraft. To this aim, a pulse shape parameter (pps) with respect to a peripheral body part (105) of the subject (P) is repeatedly registered by means of a pulse oximetry instrument (110) adapted to detect light response variations in blood vessels. A respective pulse magnitude measure is calculated based on each of a number of received pulse shape parameters (pps), and a statistical dispersion measure is calculated based on the thus-calculated pulse magnitude measure. It is investigated whether or not the statistical dispersion measure fulfils a decision criterion relative to a reference measure. An output signal (α) is generated if the decision criterion is found to be fulfilled.

摘要： A device monitors a blood path from a blood vessel access of a human subject through an extracorporeal blood processing apparatus and back to the blood vessel access. A pumping device in the blood path is operable to pump blood through the blood path from the blood withdrawal device to the blood return device. The monitoring device obtains pressure data from a pressure sensor arranged upstream of the pumping device in the blood path, and processes the pressure data for detection of a disruption of the blood path downstream of the pumping device, e.g. caused by VND (Venous Needle Dislodgement). The disruption is detected by evaluating presence/absence of cross-talk pulses at the pressure sensor, where the cross-talk pulses originate from one or more pulse generators in the extracorporeal blood processing apparatus and have propagated on a propagation path in a direction downstream of the pumping device through the blood return device, the blood vessel access and the blood withdrawal device to the pressure sensor.

摘要： A device is configured to monitor a cardiovascular property of a subject. The device obtains measurement data from a primary pressure wave sensor arranged to detect pressure waves in an extracorporeal fluid circuit in fluid communication with the cardiovascular system of the subject. The device has a signal processor configured to generate a time-dependent monitoring signal based on the measurement data, such that the monitoring signal comprises a sequence of heart pulses, wherein each heart pulse represents a pressure wave originating from a heart beat in the subject; determine beat classification data for each heart pulse in the monitoring signal; and calculate, based at least partly on the beat classification data, a parameter value indicative of the cardiovascular property. The beat classification data may distinguish between heart pulses originating from normal heart beats and heart pulses originating from ectopic heart beats. The cardiovascular property may be an arterial status of the cardiovascular system, a degree of calcification in the cardiovascular system, a status of a blood vessel access used for connecting the extracorporeal fluid circuit to the cardiovascular system, a heart rate variability, a heart rate, a heart rate turbulence, an ectopic beat count, or an origin of ectopic beats. The device may be attached to or part of a dialysis machine.

摘要： A monitoring device is included in a medical system to implement a method for prediction of a rapid symptomatic drop in a subject's blood pressure, e.g. during a medical treatment such as dialysis. To this aim, a pulse shape parameter (pPS) with respect to a pulse generator of the subject is registered by means of a pressure sensor arranged in an extracorporeal blood flow circuit coupled to a cardiovascular system of the subject (P). The pressure sensor is configured to detect pressure variations in blood vessels of the subject (P). It is investigated, during measurement period, whether or not one or more of the pulse shape parameters fulfil a decision criterion. An output signal (a) is generated if the decision criterion is found to be fulfilled, to indicate a predicted rapid symptomatic blood pressure decrease in the subject (P). The decision criterion may operate on pulse magnitude measures calculated for the received pulse shape parameters (pPS), or statistical dispersion measures calculated based on the thus-calculated pulse magnitude measures.
