Assignee: PHILIPS MEDIZIN SYSTEME BÖBLINGEN GMBH
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A method for administering a fluid to a patient, comprising:
receiving measured patient pulse signals over a measurement period corresponding to a plurality of patient respiratory cycles of the patient, wherein the patient pulse signals are detected by an oscillometric non-invasive pulse measurement method using a pressure cuff;
determining a signal envelope curve based on the measured patient pulse signals;
determining a signal fit function based on the signal envelope curve, wherein the signal fit function represents a curve progression of the signal envelope curve over the plurality of patient respiratory cycles without comprising pulse variations caused by ventilation or respiration induced heart-lung interaction;
determining a respiration envelope curve associated with the pulse variations caused by ventilation or respiration induced heart-lung interaction over the patient respiratory cycles based on the signal envelop curve and the signal fit function;
determining a respiration fit function based on the respiration envelope curve, wherein the respiration fit function represents a curve progression of the respiration envelope curve over the plurality of patient respiratory cycles;
determining an indicator associated with a patient volume responsiveness based on the signal fit function and the respiration fit function;
determining an administration of fluid based on the determined indicator; and
administering the determined administration of fluid to the patient.
