摘要:
An intracoronary catheter measures pressure distal to a lesion (Pd) and has a fluid lumen for administers adenosine to a patient's vasculature. A controller is configured to provide an injection of adenosine, wait for a period of time, measure Pd, and compare Pd to the Pd measured before the injection of the adenosine. If the difference between the pressures is small or below a threshold, the controller will stop further injections of adenosine because Pd has been determined to be at a relatively constant value. If the pressure difference is large or above a threshold, the controller will provide another adenosine injection, wait for a time period and again measure Pd and compare it to the previous Pd. This process will continue until the measured Pd reaches a relatively constant value.
摘要(中):
冠状动脉内导管测量病变远端的压力(Pd),并具有用于向患者的脉管系统施用腺苷的流体腔。 控制器配置为提供腺苷的注射,等待一段时间,测量Pd,并将Pd与注射腺苷之前测量的Pd进行比较。 如果压力差小或低于阈值,控制器将停止进一步注射腺苷,因为Pd已被确定为处于相对恒定的值。 如果压力差大于或高于阈值,控制器将提供另一次腺苷注射,等待一段时间并再次测量Pd并将其与先前的Pd进行比较。 这个过程将继续,直到测量的Pd达到一个相对恒定的值。 p>
