患者监视器 - 5个参数12.1英寸 - NSL CMS 9000 CONTEC（中国）

In medicine, Patient Monitor is the observation of a disease, condition or one or several medical parameters over time.

可以通过使用A连续测量某些参数来执行医疗监测仪(for example, by continuously measuringvital signsby a bedside monitor), and/or by repeatedly performingmedical tests(such asblood glucose monitoring与葡萄糖表在有人糖尿病）。

Transmitting data from a monitor to a distant monitoring station is known astelemetryorbiotelemetry。

Monitoring ofvital parameterscan include several of the ones mentioned above, and most commonly include at leastblood pressureand心率, and preferably alsopulse oximetryand呼吸频率。同时测量和显示相关重要参数的多模式监视器通常集成到床边监视器中critical care units，和麻醉机inoperating rooms。这些允许不断监测患者，医务人员不断了解患者的一般状况变化。一些监视器甚至可以警告待定致命cardiacconditions before visible signs are noticeable to clinical staff, such asatrial fibrillationor过早的心室收缩(PVC).

生理数据连续显示CRT,LEDorLCD屏幕为data channels沿时间轴，它们可能伴随数值读数原始数据的计算参数，例如最大，最小值和平均值，脉冲和呼吸频率等。

除了沿时间的生理参数（X轴）之外，数字医疗显示器还具有自动化数字读数of the peak and/or average parameters displayed on the screen.

Modern medical display devices commonly use数字信号处理（DSP），具有小型化,portability，以及可以一次跟踪许多不同生命体征的多参数显示。

Old类似物相比之下，患者显示为oscilloscopes，并且只有一个通道，通常保留用于心电图监测（ECG）。因此，医疗监视器倾向于高度专业化。一位显示器会跟踪患者的blood pressure, while another would measurepulse oximetry, another the ECG. Later analog models had a second or third channel displayed in the same screen, usually to monitor呼吸动作和blood pressure。These machines were widely used and saved many lives, but they had several restrictions, including sensitivity toelectrical interference, base level fluctuations and absence of numeric readouts and alarms.
