1. A method for the continuous monitoring of a hemodynamic condition of a patient, the method comprising:
measuring an electrocardiogram (ECG) signal stream at a biosignal detection device;
transmitting the ECG signal stream to a computing system;
with a set of training data comprising data from a set of healthy and sick patients, training a model to predict a physiological condition for the patient;
at the computing system, determining, a set of labels associated with the ECG signal stream, comprising, automatically, and at least in part with the trained model:
when a portion of the ECG signal stream is missing from the ECG signal stream, assigning a first label to the ECG signal stream;
when no portion of the ECG signal stream is missing from the ECG signal stream, determining a set of consolidated ECG waveform peaks based on the ECG signal stream;
checking the ECG signal stream for a set of criteria;
when at least one of the set of criteria is satisfied, assigning a second label to the ECG signal stream;
when none of the set of criteria is satisfied:
determining a set of hemodynamic stability values based on the set of consolidated ECG waveform peaks, wherein the hemodynamic stability values comprise a predicted time until hemodynamic instability; and
assigning one of a third and fourth label to the ECG signal stream based on the set of hemodynamic stability values;
displaying a visual graphic based on the set of labels at a display of a healthcare facility, wherein the visual graphic is used to initiate a treatment for the patient;
continuously updating the predicted time until hemodynamic instability, thereby enabling the continuous monitoring of the patient and an adjustment in the treatment;
classifying the hemodynamic condition of the patient as at risk based on the set of hemodynamic stability values; and
in response to classifying the hemodynamic condition of the patient as at risk, automatically initiating administration of a drug delivery to the patient at a therapeutic delivery system, wherein the therapeutic delivery system comprises at least one of: a smart pump, a smart infusion system, or an automated drug delivery system.
