DEVICES AND METHODS OF CALCULATING AND DISPLAYING CONTINUOUSLY MONITORED TIDAL BREATHING FLOW-VOLUME LOOPS (TBFVL) OBTAINED BY NON-INVASIVE IMPEDANCE-BASED RESPIRATORY VOLUME MONITORING

摘要

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.
