The determination of the inspiratory proportion coefficient InspScale and the expiratory proportion
coefficient ExpScale is determined by the following steps.
1. First, set both the inspiratory proportion coefficient InspScale and the expiratory proportion
coefficient ExpScale to 100.
2. Prepare the tidal volume tester. In VCV mode, set the frequency to 20bpm, the
inhalation-to-exhalation ratio to 1:2, PEEP to OFF, and Hold to 0; the bellows can reach the top
at the end of expiration, and then turn off flow compensation.
3. Set the tidal volume to 200mL, 300mL, 500mL, 600mL, and 800mL respectively. After the tidal
volume is stable, record the inspiratory tidal volume actually measured by the ventilator
(TVinsp-200, TVinsp-300, TVinsp-500, TVinsp-600, TVinsp -800) and expiratory tidal volume
(TVexp-200, TVexp-300, TVexp-500, TVexp-600, TVexp-800,) and the tidal volume displayed by
the tester (TV-200, TV-300, TV-500, TV-600, TV-800).
4. Calculate coefficient:
5. InspScale = ((TV-200/TVinsp-200) + (TV-300/TVinsp-300) + (TV-500/TVinsp-500) +
(TV-600/TVinsp-600) + (TV-800/TVinsp- 800))/5; rounded to an integer.
