Blood pressure measurement using pulse oximeter waveform change was compared with an oscillometric measurement and the gold standard, intra-arterial measurement, in children after cardiac surgery. Forty six patients were enrolled and divided into groups according to weight. Simultaneous blood pressure measurements were obtained from the arterial catheter, the oscillometric device, and the pulse oximeter. Pulse oximeter measurements were obtained with a blood pressure cuff proximal to the oximeter probe. The blood pressure measurements from the pulse oximeter method correlated better with intra-arterial measurements than those from the oscillometric device (0.77-0.96 v 0.42-0.83). The absolute differences between the pulse oximeter and intra-arterial measurements were significantly smaller than between the oscillometric and intra-arterial measurements in children less than 15.0 kg. The pulse oximeter waveform change is an accurate and reliable way to measure blood pressure in children non-invasively, and is superior to the oscillometric method for small patients.
在心脏手术后的儿童中，将利用脉搏血氧饱和度仪波形变化测量血压的方法与示波测量法以及金标准——动脉内测量法进行了比较。纳入了46名患者，并根据体重分组。同时从动脉导管、示波测量设备和脉搏血氧饱和度仪获取血压测量值。脉搏血氧饱和度仪测量是在靠近血氧饱和度仪探头处使用血压袖带进行的。与示波测量设备相比，脉搏血氧饱和度仪法测得的血压与动脉内测量值的相关性更好（0.77 - 0.96对0.42 - 0.83）。在体重小于15.0千克的儿童中，脉搏血氧饱和度仪与动脉内测量值之间的绝对差值明显小于示波测量法与动脉内测量值之间的差值。脉搏血氧饱和度仪波形变化是一种准确、可靠的无创测量儿童血压的方法，对于小患者优于示波测量法。
