We currently use 8 liters per minute for VI and 4 liters per minute for VE. The lower VE flow was recommended to decrease expiratory resistance for the infant, thus decreasing WOB, oxygen consumption, and FiO2. Some of our staff think the VE should be higher to facilitate CO2 washout. We would like to hear what other units are using.

We have the same views about VIVE (lower expi flow for decreasing resistance, and higher for CO2 washout).
In addition, you might want to increase expi flow in order to permit spontaneous breating during mandatory expiratory time (the patient will be able to get a Vt with that flow).
