The invention provides a method and apparatus for detecting respiratory rate, comprising the steps of: sampling a set of respiratory rate data in a time sequence; determining the variation degree for the set of respiratory rate data; determining the base length according to the variation degree for the set of respiratory rate data; calculating the weighted average length according to the base length; calculating the real-time degree for each of the set of respiratory rate data according to the variation degree for the set of respiratory rate data, the sequence number indicating the position for each of the set of respiratory rate data and the weighted average length, the sequence number indicating the position for a preceding respiratory rate data is less than the sequence number indicating the position for a following respiratory rate data; and calculating the weighted average respiratory rate according to the weighted average length and the real-time degree. According to the invention, the calculated respiratory rate data is advantageous in being both real time degree and smoothness of respiratory rate.
