Patient Monitor – 5 Parameters 12.1″ – NSL CMS 9000 Contec (China)

在医学中，患者监测器是对疾病，病情或一个或几个医疗参数的观察。

It can be performed by continuously measuring certain parameters by using amedical monitor(for example, by continuously measuringvital signsby a bedside monitor), and/or by repeatedly performingmedical tests(such as血糖监测with aglucose meterin people with糖尿病).

Transmitting data from a monitor to a distant monitoring station is known astelemetry或者biotelemetry。

监视vital parameterscan include several of the ones mentioned above, and most commonly include at leastblood pressure和心率，最好也pulse oximetry和respiratory rate。Multimodal monitors that simultaneously measure and display the relevant vital parameters are commonly integrated into the bedside monitors in重症监护单位, and theanesthetic machinesinoperating rooms。These allow for continuous monitoring of a patient, with medical staff being continuously informed of the changes in general condition of a patient. Some monitors can even warn of pending fatalcardiacconditions before visible signs are noticeable to clinical staff, such asatrial fibrillation或者premature ventricular contraction(PVC).

生理数据连续显示CRT,引领或者LCDscreen asdata channelsalong the time axis, They may be accompanied bynumerical readoutsof computed parameters on the original data, such as maximum, minimum and average values, pulse and respiratory frequencies, and so on.

Besides the tracings of physiological parameters along time (X axis), digital medical displays have automatednumeric readouts屏幕上显示的峰值和/或平均参数。

现代医疗展示设备通常使用digital signal processing（DSP），具有小型化,portability, and multi-parameter displays that can track many different vital signs at once.

老analog相比之下，患者显示为oscilloscopes, and had one channel only, usually reserved for electrocardiographic monitoring (ECG). Therefore, medical monitors tended to be highly specialized. One monitor would track a patient’sblood 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 monitorrespirationmovements andblood pressure。这些机器被广泛使用并挽救了许多生命，但它们有几个限制，包括对电干扰, base level fluctuations and absence of numeric readouts and alarms.
