Hemodynamic monitor for triaging patients with aortic stenosis

A hemodynamic monitor for detecting aortic stenosis, the hemodynamic monitor comprising:

• a non-invasive blood pressure sensor comprising an inflatable blood pressure bladder, a pressure controller pneumatically connected to the inflatable blood pressure bladder, and an optical transmitter and an optical receiver that are electrically connected to the pressure controller;
• an integrated hardware unit comprising:
• a system processor;
• a system memory;
• a display comprising a user interface;
• and
• wherein the system memory comprises instructions that, when executed by the system processor, are configured to:
• adjust, by the pressure controller, a pressure within the inflatable blood pressure bladder to maintain a constant volume of an artery of a patient for a period of time based on a feedback signal generated by the optical transmitter and the optical receiver;
• generate an arterial pressure waveform data of the patient based on the adjusted pressure within the inflatable blood pressure bladder over the period of time;
• extract a plurality of signal measures from the arterial pressure waveform data of the patient;
• extract input features from the plurality of signal measures that are indicative of an aortic stenosis score of the patient;
• determine the aortic stenosis score of the patient based on the extracted input features;
• generate a first sensory alarm signal configured to generate a first sensory alert that indicates that the patient has severe aortic stenosis when the aortic stenosis score exceeds a threshold score, or generate a second sensory alarm signal configured to generate a second sensory alert that indicates that the patient does not have severe aortic stenosis when the aortic stenosis score is below the threshold score;
• transmit the first sensory alarm signal or the second sensory alarm signal to the user interface;
• and
• output the first sensory alert or the second sensory alert through the user interface.
