We don’t have to calculate this

Ericksen-Minimize resistance in the system- ideal to have short, straight, wide and no curves
Like an Old Fashion drink glass :p
Resistance imposes a strain with ventilatory modes where the patient must do part or all of the __________.
A) expiration
B) moving
C) work
D) inspiration
C) Work (inspiration and expiration)
If we are adding more things that the patient has to initiate breaths through, it makes it harder to breath through, increasing resistance

D) parallel
Increased WOB = Increased resistance
