Abstract: Systems and methods of evaluating a patient comprise the steps of obtaining temporal data of the patient after an event, monitoring a plurality of patient parameters, compiling patient data based on the temporal data and patient parameters, determining a state or change in state of the patient based on the compiled patient data, and alerting medical staff of the state or change in state.

Abstract: Methods and systems of displaying flow-volume loops of a patient and variability of the flow-volume loops across measured breaths are disclosed. The methods comprise obtaining a physiological dataset of the patient on a data acquisition device, applying a smoothing and curve fitting algorithm to the physiological dataset on a processing device to obtain real-time volume and flow data at a plurality of time instances, applying a visualization algorithm on the processing device to the volume and flow data to create a series of flow-volume loops based on the volume and flow data, and outputting a plot of the flow-volume loops on a display device to aid evaluation or diagnosis of the patient.
