Set the simulated pulse of simulated tester to 75bpm,the oxygen saturation figure are set to 70%, 80%, 90%, 96% and 100%, observe and record the matching supporting device oxygen saturation indication,the result of test conform 5.2. Connect correctly patient monitor and oximeter to collect and tranfer patient’ spo2 and signal of pulse’ rate. s s Not suitable for state of weak perfusion and movement to monitor. the probe is not suitable for long-term monitoring, should be checked every 4 hours or change other finger to measure . Put it in a sealed plastic bag after cleaning and drying.The surrounding environment should meet the following conditions: Temperature: - 5 ℃ ~ + 40 ℃, relative humidity is not more than 80%, atmospheric pressure: 45kpa to 110kpa. temperature: 0 ℃ to 40 ℃;Relative humidity: no more than 80%;Pneumatic: 86kpa to 106kpa.
