How can we best manage a high respiratory drive and low PetCO2 that lead to low pressure support?

Managing a high respiratory rate and low CO2

If the patient is breathing spontaneously with a high respiratory drive and a high respiratory rate (RR), the respiratory rate might exceed the upper limit for the RR target zone. In this case, INTELLiVENT-ASV (Not available in the US and some other marketsA​) will react by increasing the %MinVol. If the tidal volume is above the target, INTELLiVENT-ASV will also decrease the pressure support (Pinsp). PetCO2 will be below the lower target range due to the high respiratory drive and the high respiratory rate.

See the flowchart below for causes and action.
