Anaesthesia for patients in a Magnetic Resonance Imaging (MRI) scanner provides some problems for the design of both the anaesthetic and the monitoring equipment. This report presents a technique for continuously displaying the heart rate during anaesthesia for children in an MRI scanner. The monitoring system used light to detect differences in skin capillary circulation, and the light was transferred to and from the patient via fiberoptic cables. After amplification, the signal was displayed "on line" on a cardioscope, thus continuously presenting heart rate and, in part, a qualitative view of the skin vascular resistance.
为在磁共振成像（MRI）扫描仪中的患者实施麻醉，给麻醉设备和监测设备的设计带来了一些问题。本报告介绍了一种在MRI扫描仪中为儿童麻醉期间持续显示心率的技术。该监测系统利用光线检测皮肤毛细血管循环的差异，光线通过光纤电缆传输至患者并从患者传出。信号经放大后在心脏示波器上“在线”显示，从而持续呈现心率，并部分呈现皮肤血管阻力的定性视图。
