  • System for measuring the mean arterial pressure
    Patent number: 11638529
    Abstract: The present invention relates in particular to the field of anesthesia and to a method for real-time evaluation of the mean arterial pressure of a patient from plethysmography measurements. It also relates to a method for treating a patient comprising by continuously evaluating the mean arterial pressure of the patient, based on values continuously calculated by plethysmography.

  • Method for the continuous evaluation of the ventriculo-aortic coupling of at-risk patients by analysis of pressure-flow loops
    Patent number: 10653364
    Abstract: The invention relates to the field of cardiovascular resuscitation and, more specifically, it concerns a novel method of monitoring the ventriculo-aortic coupling of at-risk patients on the basis of the aortic pressure/flow loop of the patient and the zoning of this loop.

  • Method of prognosis associated with cases of postpartum hemorrhage
    Patent number: 8784313
    Abstract: Novel prognosis methods associated with cases of postpartum haemorrhage providing a predictive test enabling practitioners to provide better management of patients suffering from postpartum haemorrhage. Different risk factors exist on which a score allowing prediction of the need to carry out invasive procedures to stop bleeding has been developed.

  • NOVEL METHOD OF PROGNOSIS ASSOCIATED WITH CASES OF POSTPARTUM HEMORRHAGE
    Publication number: 20130190585
    Abstract: The present invention relates to an in vitro method of prognosis for the arrest of bleeding in a patient suffering from postpartum haemorrhage in the absence of an invasive procedure, comprising the following steps: (a) determining, using a biological sample from said patient, the plasma fibrinogen concentration, the blood troponin concentration and also the prothrombin time; (b) studying at least two clinical markers for said patient, selected from the group comprising heart rate and the presence of placentation abnormalities; (c) calculating a score Z according to the following equation: Z=a+b+v+d+e; where a is associated with the existence of placentation abnormalities in said patient, with a being 0 when no placentation abnormality is observed in said patient and a being 1 when one or more placentation abnormalities are observed in said patient; where b is associated with the heart rate of said patient, with b being 0 when the heart rate of said patient is less than or equal to 115 bpm (beats per minute)
