Abstract
A system for monitoring arterial pressure of a patient determines a score that is predictive of responsiveness of the patient to a therapy. Sensed hemodynamic data representative of an arterial pressure waveform of the patient are received by a hemodynamic monitor. Magnitude data and trend data are derived from the hemodynamic data. The score that is predictive of the responsiveness of the patient to the therapy is determined based on the magnitude data and the trend data of the hemodynamic parameter. A representation of the score is output.

A system for monitoring arterial pressure of a patient and determining one or more scores that are predictive of responsiveness of the patient to a corresponding therapy, the system comprising:
- a hemodynamic sensor that produces sensed hemodynamic data representative of an arterial pressure waveform of the patient;
- a system memory that stores hemodynamic therapy scoring software code;
- a user interface;
- and
- a hardware processor that is configured to execute the hemodynamic therapy scoring software code to:
- derive, from the sensed hemodynamic data representative of the arterial pressure waveform of the patient, first magnitude data and first trend data of a first hemodynamic parameter selected from the group consisting of a stroke volume variation (SVV), a pulse pressure variation (PPV), a stroke volume (SV), and a stroke volume index (SVI), wherein the first hemodynamic parameter is indicative of a condition treatable by an intravenous delivery of a saline fluid to the patient;
- derive, from the sensed hemodynamic data representative of the arterial pressure waveform of the patient, second magnitude data and second trend data of a second hemodynamic parameter selected from the group consisting of a systemic vascular resistance (SVR) and a systemic vascular resistance index (SVRI), wherein the second hemodynamic parameter is indicative of a condition treatable by an intravenous delivery of a vasopressor to the patient;
- determine a first magnitude sub-score based on the first magnitude data and a second magnitude sub-score based on the second magnitude data;

- and
- output, via the user interface, a representation of the first score that is predictive of responsiveness of the patient to the intravenous delivery of the saline fluid and a representation of the second score that is predictive of responsiveness of the patient to the intravenous delivery of the vasopressor.
