摘要:
A physiological monitoring system may determine physiological information, such as physiological rate information, and other information, such as noise information, from a physiological signal. The system may generate a difference signal based on the physiological signal and sort the difference signal to generate a sorted difference signal. The system may determine slope values for multiple segments of the sorted difference signal. The system may determine two end groups of the segments and determine at least one threshold based on the end groups. One or more end data points of the sorted difference signal may be identified as being associated with noise based on the at least one threshold. The system may determine a value indicative of noise based on the identified data points.
