1, the monitoring data should be accurate, such as oxygen saturation, blood pressure and so on. Not allowed to easily cause misdiagnosis, serious medical errors.
2, anti-interference ability to be strong. The simplest way to test is: the monitor to the operating room with, on the knife to see the interference is not big; withdraw the knife to see the waveform after the recovery is not fast. A good monitor in the withdrawal of the knife, the waveform within 3-5 seconds to recover quickly.
Note: Any monitor will be interfered with, the difference is the strength of anti-interference ability.
3, good scalability.
4, good after-sales service. This goes without saying.
