打开电源，接通血氧计。
提供借用的输注器、生理监察器及脉搏血氧计，以供医院应急之用；
Providing loaner unit of infusion pump , physiologic monitor , pulse oximeter etc for urgent use by hospitals.
当心血管搏动微弱甚至使用体外循环时，脉搏血氧计已无读数，但组织血氧参数无损监测仪仍能提供信息。
When the cardiovascular pulsation is weak even under cardiopulmonary bypass (CPB), pulse oxygen saturation at finger tip cannot be detected, but tissue oxygenation still can be monitored by NIRS.
方法：心血通经腹腔注射后，采用电磁流量计分别测量冠脉血流量，以血氧计测定血氧含量，计算心肌耗氧量。
Methods: After Xinxuetong was administrated intraperitoneally, the amount of blood in the coronary arteries and the amount of output from heart were determined by electric magnetic flowmeter.
各组应用激光多普勒血流计（LDF）及血氧饱和度（SpO2）检测计进行皮肤微循环血流监测，并对2组皮瓣成活面积及微血管造影的结果进行比较。
The laser Doppler flowmeter(LDF) and oxyhemograph(SPO2) were applied to detect skin microcirculation. The survival area and the results of microangiography of the two groups were compared.
