Abstract
This disclosure relates to methods and apparatus for detecting respiratory rate. The method for detecting respiratory rate may include: sampling respiratory waveform data in a time sequence; detecting respiratory cycles from the sampled respiratory waveform data; calculating variation degree for the sampled respiratory waveform data; calculating base length base on the variation degree; calculating smoothed length base on the base length; calculating real-time degree for each respiratory cycle base on the variation degree, sequence number of each respiratory cycle, and the smoothed length; and calculating respiratory rate base on the smoothed length and the real-time degree.
