了解呼吸模式的病理不稳定性可以为危重婴儿的心肺状态及其成熟水平提供有价值的见解。本文是关于早产儿呼吸频率的测量。我们比较了由胸阻抗肺图、心电图得出的呼吸节律和ppg得出的呼吸节律估计的速率与由临床工作人员在165次人工呼吸计数中提供的呼吸检测参考标准中测量的速率。我们证明，在40-80bpm（每分钟呼吸次数）范围内，可以从所有来源获得准确的RR估计。我们还得出结论，使用基于ECG或PPG的间接方法对这一人群构成了根本性的挑战，因为他们在快呼吸频率（高于80bpm）时表现不佳。
Knowledge of the pathological instabilities in the breathing pattern can provide valuable insights into the cardiorespiratory status of the critically-ill infant as well as their maturation level. This paper is concerned with the measurement of respiratory rate in premature infants. We compare the rates estimated from the chest impedance pneumogram, the ECG-derived respiratory rhythms, and the PPG-derived respiratory rhythms against those measured in the reference standard of breath detection provided by attending clinical staff during 165 manual breath counts. We demonstrate that accurate RR estimates can be produced from all sources for RR in the 40-80bpm (breaths per min) range. We also conclude that the use of indirect methods based on the ECG or the PPG poses a fundamental challenge in this population due to their poor behavior at fast breathing rates (upward of 80bpm).
