[0038] Example:
[0039] A pressure sensor of a respiratory support device is used as an example for description.
[0040] like figure 1 As shown, first determine the key indicators of the pressure sensor, and the key indicators need to be able to intuitively and accurately reflect the performance of the pressure sensor.
[0041] In the present invention, the key indicators for the pressure sensor mainly include three items: reading accuracy, reading stability, and reading delay.
[0042] The reading accuracy is mainly measured by comparing the difference between the reading value of the sensor and the reading value of the standard pressure gauge. The specific measurement is to calculate the absolute quantity, that is, the absolute value of the difference between the reading value P of the sensor and the reading value P0 of the standard pressure gauge. , the formula is M=|P-P0|. It is generally considered that in the interval (0, 0.5), the reading accuracy score is 10 point...
