故障现象１血氧饱和度无波形曲线显示和脉搏跳动显示分析检修ＮＰＢ -４００监护仪血氧饱和度测量是将传感器连接在搏动的微动脉血管床上。该传感器有一个双重光源和一个感光器。当手指放入指夹套内。微动脉血管床不断搏动。在收缩与舒张期间。随着血流量的增减 ,不同程度地吸
Symptom 1 Oxygen saturation No waveform curve display and pulse beats Display analysis Maintenance NPB -400 monitor SpO2 measurement is connected to the sensor in the pulsating micro-vascular bed. The sensor has a double light source and a photoreceptor. Put your finger into the finger grip. Micro-arterial vascular bed constantly beating. During contraction and relaxation. As the blood flow increases and decreases, suck to different degrees
