Abstract: A system for determining a pulse velocity wave comprises an interface for receiving a signal indicating the proximal blood pressure in an artery and for receiving a signal indicating distal blood pressure in the artery. A processing device is configured to determine a proximal rising edge between a diastolic pressure and the systolic pressure of the proximal signal; determine a proximal pressure peak prior to the proximal rising edge; determine a distal rising edge between a diastolic pressure and a systolic pressure of the distal signal; determine a distal pressure peak prior to the distal rising edge and to determine whether the distal pressure peak is in phase advance with respect to the proximal pressure peak; and determine a propagation velocity of a regressive pulse wave depending on the phase advance of the distal pressure peak.

Abstract: An apparatus for determining coronary pulse wave velocity uses proximal and distal pressure sensors that are separated by a known distance to collect waveforms with rising and falling edges and to use times between those edges together with the known distance to determine coronary pulse wave velocity.

Abstract: The invention relates to the field of technological assistance for anaesthesia and intensive care practitioners, as well as to the field of simple, reliable medical monitoring for managing anaesthesia and/or predicting deleterious medical events. The invention aims to provide a system enabling prevention and anticipation of procedures necessary for patients and/or maintenance of patients in a suitable anaesthetic state for a surgical operation at a given time. For this purpose, the invention provides a method of predicting abnormal medical events and/or assisting in diagnosis and/or monitoring, comprising the continuous, real-time detection of a concomitant occurrence of a temporary inefficiency in cardiac baroreceptor reflex and an activation of non-baroreceptor reflex cardiovascular control. The invention also relates to the device used to implement said method.

The invention aims to provide a system enabling prevention and anticipation of procedures necessary for patients and/or maintenance of patients in a suitable anaesthetic state for a surgical operation at a given time. For said purpose, the invention provides a method of predicting abnormal medical events and/or assisting in diagnosis and/or monitoring, which is characterised in that it essentially comprises the continuous, real-time detection of a concomitant occurrence of a temporary inefficiency in cardiac baroreceptor reflex and an activation of non-baroreceptor reflex cardiovascular control. The invention also relates to the device used to implement said method.
