Information from pulse oximeter waves confirms the presence of a pulse and helps obtain waves from tissue when the supplying artery is not readily accessible.
This study determined the predictive value of pulse oximeters for detecting improved arterial pulses after angiography.
This cross-sectional, multi-center study included 467 4-day-old to 12-year-old patients and was conducted from January 2012 to January 2016. Angiographies were performed on 12-year-old or younger children for various medical reasons using venous, arterial, or both types of paths. The posterior malleolar or dorsalis pedis were palpated in punctured lower extremities. In the absence of a pulse, pulse oximetry was performed to identify pulse curves at 1 hour, 6 hours, and 12 hours after each angiography.
Pulse oximetry displayed the pulses of 319 patients immediately following each angiography. Of these, 262 patients had palpable pulses at 6 hours after angiography (P < 0.0001), while 57 patients had no palpable pulse. Of these 57 patients, 15 had no palpable pulse at 12 hours after angiography (P < 0.0001). The odds of pulse improvement in children 6 hours after catheter angiography were 76% for the arterial path, 90% for the venous path, and 83.2% for both paths. At 12 hours after catheter angiography, these values increased to 91.6% for the arterial path, 100% for the venous path, and 95.9% for both paths.
The pulse oximeter can display the pulse curve immediately (1 hour) after angiography and indicate pulse improvement at 12 hours maximally following an angiography. In this case, heparin alone may be used instead of thrombolytic agents.
脉搏血氧仪波形信息可确认脉搏的存在，并且在供应动脉难以触及的情况下有助于获取组织波形。
本研究确定了脉搏血氧仪在血管造影术后检测动脉搏动改善情况的预测价值。
这项横断面、多中心研究纳入了467例年龄在4日至12岁的患者，研究于2012年1月至2016年1月进行。因各种医学原因，对12岁及以下儿童采用静脉、动脉或两种路径进行血管造影。对穿刺的下肢触诊后踝或足背动脉。在无脉搏的情况下，在每次血管造影术后1小时、6小时和12小时进行脉搏血氧测定以识别脉搏曲线。
每次血管造影术后，脉搏血氧测定立即显示了319例患者的脉搏。其中，262例患者在血管造影术后6小时可触及脉搏（P<0.0001），而57例患者无可触及的脉搏。在这57例患者中，15例在血管造影术后12小时无可触及的脉搏（P<0.0001）。导管血管造影术后6小时，儿童脉搏改善的几率在动脉路径为76%，静脉路径为90%，两种路径均为83.2%。在导管血管造影术后12小时，这些数值在动脉路径升至91.6%，静脉路径为100%，两种路径均为95.9%。
脉搏血氧仪可在血管造影术后立即（1小时）显示脉搏曲线，并在血管造影术后最多12小时显示脉搏改善情况。在这种情况下，可单独使用肝素而非溶栓剂。
