Patent ID: 8517950

Claim:
An apparatus for determining conditions of hemorrhage in a subject, comprising: at least an input line for: receiving one or more electrical signals coming from one or more electrodes predisposed to detect cardiac activity; and receiving a signal coming from a peripheral sensor predisposed to operate in a predetermined peripheral section of the subject's body; a control unit connected to the input line and configured for: determining, from the one or more electrical signals coming from the one or more electrodes through the input line, an instant of generation (TG j ) in which a pressoric wave is generated in relation to a heartbeat, determining, from the signal coming from the peripheral sensor through the input line, an instant of peripheral propagation (TP j ) in which the pressoric wave reaches the predetermined peripheral section, calculating at least one value of an indicator parameter (iHAT) as a function of a temporal delay (δT j ) occurring between the instant of generation (TG j ) and the instant of peripheral propagation (TP j ) divided by the temporal interval occurring between two successive heartbeats (ΔT j ), verifying whether or not said at least one value of the indicator parameter (iHAT) satisfies a reference criterion, and determining whether a condition of hemorrhage is present or not in the subject depending upon an outcome of said verifying.
