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.
