摘要： A method and apparatus for estimating a respiratory rate of a patient. The method comprises the steps of recording respiratory sounds of the patient, deriving a plurality of respiratory rates from the recorded sounds using a plurality of respiratory rate estimating methods and applying a heuristic to the plurality of derived respiratory rates, the heuristic selecting one of the derived respiratory rates. The selected respiratory rate is the estimated respiratory rate. The apparatus comprises at least one sensor recording respiratory sounds of the patient, a plurality of respiratory rate processors, each of the processors comprising a respiratory rate calculating method, a heuristic means for selecting one of the calculated respiratory rates and a display means for displaying the selected respiratory as the estimated respiratory rate.
摘要翻译：一种用于估计患者的呼吸频率的方法和装置。该方法包括以下步骤：记录患者的呼吸声音，使用多种呼吸率估计方法从记录的声音中导出多个呼吸频率，并将启发式应用于多个派生呼吸频率，启发式选择一个导出呼吸频率。选择的呼吸频率是估计的呼吸频率。该装置包括至少一个记录患者的呼吸声音的传感器，多个呼吸率处理器，每个处理器包括呼吸率计算方法，用于选择所计算的呼吸频率之一的启发式装置和显示装置，选择呼吸作为估计的呼吸频率。

摘要： Respiratory rate can be calculated from an acoustic input signal using time domain and frequency domain techniques. Confidence in the calculated respiratory rate can also be calculated using time domain and frequency domain techniques. Overall respiratory rate and confidence values can be obtained from the time and frequency domain calculations. The overall respiratory rate and confidence values can be output for presentation to a clinician.
