6.Power protection →
6.1. If the main unit is connected to other devices such as module, external module rack, mouse, keyboard, USB drive, and scanner, please first disconnect these devices from the host. If the main unit can be started up after the disconnection, it can be suspected that the external device fails, triggering power protection of the main unit
6.2. If the main unit is not connected to other devices, check whether there is a short circuit failure with the rear panel of the internal module rack or the main control board, causing protection of the power output
1.The sensor is not installed properly in position or the patient experiences vigorous movement;
2.The ipsilateral arm blood pressure is measured or there is ipsilateral lateral compression;
3.Avoid interference from a strong light environment on signals;
4.Poor peripheral circulation: such as shock and low finger temperature;
5.Fingers: Factors such as nail polish, thick cocoon, broken finger, and long nail affect the light transmittance;
6.Intravenous injection of colored drugs;
7.Determine whether the SpO2 probe is damaged by replacing it
1.Check if the gas circuit is bent or blocked
2.Determine whether the gas transfer tube/cuff is leaking through cross replacement testing
1.Main unit cleaning:
1.1. Dip a dust-free cloth in an appropriate amount of water or 75% ethanol, and squeeze it dry;
1.2. Wipe the display screen;
1.3. Wipe the surface of the main unit, module, or module rack, noting to avoid the equipment interfaces and metal parts;
1.4. Use a dry dust-free cloth to wipe off the cleaning agent from the surface of the equipment, and place the equipment in a cool and ventilated environment to air dry
2.Cleaning of accessories (gas transfer tube for blood pressure, SpO2 cable, SpO2 probe, ECG cable):
2.1. Use a dust-free cloth moistened with water or 75% ethanol to wipe the accessories;

1.Check the sticking quality of electrode and reduce patient movement.
2.Adjust the RESP threshold automatically or manually.
Cause analysis:
1.Deviation caused by different measurement principles: ? Mindray NIBP uses the oscillation method for blood pressure measurement. According to the ISO81060-2-2013 non-invasive automated sphygmomanometer standard, the NIBP equipment can be verified by referring to the auscultation or invasive method. ? IBP is a continuous blood pressure measurement method, and its measurement results can reflect the patient's blood pressure changes in real time; NIBP is an intermittent blood pressure measurement method, and its measurement results reflect the blood pressure status over a period of time during the measurement.
2.Deviation caused by different measurement sites: ? A typical measurement method in clinical practice is to take the radial artery of one arm for IBP measurement, and the brachial artery of the other arm for NIBP measurement. Due to differences in the blood pressures of the left and right arms of the human body and different sites of the same arm, the deviations in the IBP and NIBP measurement results can be increased.
3.Deviations caused by non-standard IBP and NIBP measurements: ? IBP sensor incompatibility (zero drift, poor contact) ? Improper piercing position of IBP (the piercing probe tightly adheres to blood vessel wall); ? Improper monitor settings (IBP sensitivity); ? An error found in IBP zero calibration (at the same level as the heart); ? Bubbles or vibrations found in the IBP liquid circuit (affecting accuracy); ? Non-standard NIBP measurement (improper cuff size, external interference)
