SYSTEM FOR PERFORMING HISTOGRAM ANALYSIS OF THE TIME BASED CAPNOGRAPHY SIGNALS AND METHOD OF OPERATION THEREOF

摘要

A gas concentration monitoring system (100 600) may include a processor (110 610) configured to detect a concentration of a selected gas in a sample gas flow obtained from a physical interface (107) to a patient (101); form a dataset including a plurality of data points each data point corresponding to the detected concentration of the selected gas within the sample gas flow during a sampling time; group the data points according to a frequency of occurrence of the data points within the sampling time; and/or determine at least one of a signal confidence and signal quality based on relative characteristics between the groups of data points.
