In previous studies, oscillometric blood pressure measured from the supraorbital artery has been shown to agree quite well with pressure measured from the brachial artery in normal subjects. In this study, surgical patients whose conditions warranted the use of invasive blood pressure monitoring during the surgery were chosen. We compared systolic and diastolic blood pressure measured oscillometrically from the supraorbital artery with intraarterial blood pressures, measured invasively from the radial artery. A pressure bladder was attached to the forehead of each patient. The bladder was connected to a forehead blood pressure monitor. A catheter was inserted in a radial artery, and connected to a pressure monitor. Forehead blood pressure was measured every 5 min. Radial arterial pressure was averaged over the same period during which the forehead measurement was made. Blood pressures measured with the two methods were compared. For the systolic pressure, the difference between the two methods was -9.9 +/- 17.9 mm Hg (mean +/- SD). For diastolic pressure, the difference was -8.0 +/- 10.9 mm Hg. There was a significant difference between the two methods in the patient population chosen in this study.
在先前的研究中，已表明在正常受试者中，通过眶上动脉测量的示波血压与通过肱动脉测量的血压相当吻合。在本研究中，选择了手术中病情需要使用有创血压监测的手术患者。我们将通过眶上动脉示波测量的收缩压和舒张压与通过桡动脉有创测量的动脉内血压进行了比较。将一个压力气囊附着在每位患者的前额。该气囊连接到前额血压监测仪。将一根导管插入桡动脉，并连接到压力监测仪。每5分钟测量一次前额血压。在前额测量的同一时间段内，计算桡动脉压的平均值。比较了两种方法测量的血压。对于收缩压，两种方法之间的差异为-9.9±17.9毫米汞柱（平均值±标准差）。对于舒张压，差异为-8.0±10.9毫米汞柱。在本研究选择的患者群体中两种方法之间存在显著差异。
