Maintenance: due to the characteristics of sensor sensor itself and the detected location of the patients often in practice, so it is easy to damage the parts, is an important part of the more expensive. In order to extend their period of use, reduce the cost of treatment, we should do more for their maintenance work. Often communicate with the medical staff, guide them to correct operation and maintenance of monitor and sensor. Not fold, pull transmission wire sensor; probe cannot fall, touch sensor probe, such as oxygen saturation temperature, invasive blood pressure probe. For the non invasive blood pressure cuff, in the absence of strapping on the patient host at this time cannot be measured, so as to avoid damage to the inflation of the airbag. When the monitor to care for a long time without the need for monitoring the blood oxygen saturation, to turn off this feature through adjusting the configuration of the system, if the machine has this setting or unplug the oxygen saturation of blood is connected to the host interface monitors are generally through the interface to connect each sensor, so as to prolong the service life of this kind of sensor.

Sensor probe easily stained with sweat, blood and other dirt, to avoid corrosion probe and measurement to regularly according to the user's manual provides a method of cleaning the probe. System maintenance: the monitor system is set properly, or even wrong, often for health care workers in trouble. For example: a wave shape, without heart rate; not measuring blood pressure in hypertensive patients; the parameters of normal, but the alarm time and so on, these are likely to be caused by the wrong system settings. Therefore, should always check the maintenance system to ensure the reliability of monitoring, optimality, i.e. the optimal configuration. Although the monitor various, specific methods of system settings of each are not identical, but most of them have the following aspects: patient information in the information should pay attention to is the types of patients choose to correct. Generally divided into neonatal, adult and children, they were measured using different schemes, if the wrong will affect the measurement accuracy, and even can not be measured. For example, noninvasive blood pressure is likely to detect and display the error.
