Embodiment 1
[0040]referencefigure 1 As shown, this embodiment provides a method of detecting a pulmonary ventilation based on a flow-volume ring diagram, including:
[0041]Step S1, obtain the electrical impedance signal to be tested, the electrical resistance signal includes four regions of the upper left (LU zone), the upper right (RU region), the lower left (LL area), and the left (LL area), and the lower right (RL area) in the upper right (RU region), the left (LL region) and the left (LL area) Electrical impedance signal ZLu (n), zRU (n), zLL (n) and zRL (n), where n is a sample sample number.
[0042]When the resistance signal is taken as the respiratory action required to be tested in accordance with the respiratory action required for the clinical lung function, the flow rate-flow vendor test is tested, and the biological resistance measurement system for the four-pair of composite electrodes attached to the chest surface designation is measured. .
[0043]In one embodimentfigure 2 The electrode...
