Photoplethysmography (PPG) is an increasingly popular health and well-being tool for monitoring heart rate and oxygen saturation. Due to the pigmentation and hairiness of dogs and cats, a pulse oximeter is routinely placed solely on the tongue. As this approach is feasible only for pet monitor use during surgical procedures, we investigate PPG signal quality on several other measurement sites that would be better tolerated by conscious animals.
Acquired PPG signals are analyzed by four signal quality indices: mean baseline, signal power, kurtosis, and tolerance score.
In dogs, the metacarpus and tail can be substituted for oral pulse oximeter placement since both measurement sites exhibited high PPG signal kurtosis and were considered well-tolerated. In cats, the digit could be used with some limitations.
Pet monitors with pulse oximeter probes adjusted to promising measurement sites could enable veterinarians and owners to monitor animals when fully awake.
光电容积脉搏波描记法（PPG）是一种越来越受欢迎的健康和福祉监测工具，可用于监测心率和血氧饱和度。由于狗和猫的色素沉着和多毛，脉搏血氧仪通常仅放置在舌头上。由于这种方法仅适用于手术过程中的宠物监护使用，因此我们研究了其他几个测量部位的 PPG 信号质量，这些部位更能被有意识的动物所耐受。
通过四个信号质量指数分析获得的 PPG 信号：平均基线、信号功率、峰度和容限得分。
在狗中，掌部和尾部可以替代口腔脉搏血氧仪的位置，因为这两个测量部位的 PPG 信号峰度都很高，并且被认为是可以很好耐受的。在猫中，指部也可以使用，但有一些限制。
调整到有前途的测量部位的宠物监护仪脉搏血氧仪探头可以使兽医和主人在动物完全清醒时对其进行监测。
