In No Air Mix mode, the deviations are smaller)
The applied minute volume MV depends on the atmospheric pressure. If the atmospheric pressure falls from
1000 hPa to 900 hPa (corresponding to an altitude of approx. 1000 m), the dosed tidal volume VT increases by
approx. 10 %, because the quantity of gas dosed occupies a larger space at a lower atmospheric pressure.
The increased MV and VT, due to atmospheric pressure changes, are not shown in the display.
