6. ExpScale = ((TV-200/TVexp-200) + (TV-300/TVexp-300) + (TV-500/TVexp-500) +
(TV-600/TVexp-600) + (TV-800/TVexp- 800))/5; rounded to an integer.
7. Reset the inspiratory proportion coefficient and expiratory proportion coefficient of the ventilator
according to the calculated values.
7.3.6. Calibration of the Flow Valve
Warning
Calibration of the flow valve requires factory-trained engineers to use special
equipment. Users are not recommended to perform this operation.
