pressure set
PPVC
controls pressure and volume by vent
lowest possible pressure
TV delivered at set rate
SIMV
used for weaning
number of breaths in coordination with respiratory effort
used to assist pt breathing
pressure support vent
small amount of pressure on inspiration
pt initiates all breath
delivers specific pressure
vent assists but pt regulates RR and TV
VS
a) TV and PEEP are set
b) Pt initiates breathing
CPAP
a) Continuous pressure is maintained in airways to prevent collapse
b) Pt regulates all other respiratory function
