plateau pressure should always be below peak pressure T/F
T
if the ptat and peak are the same range, means the pt has stiff lungs T/F

if you increase pressure you decrease
BP
decreased venous return to the heart is due to:
increased intrathoracic pressure
increased vt

dec aortic pressure
dec in CO
PEEP dec CO more than CPap
if you decrease CO you will also decrease
blood flow to liver and kidneys
if pt lacks CO2, it will be more difficult to produce and process
produce urine
process drugs
bc of lack of CO, organs/kidneys can't work like they should, so if pt is sedated, kidneys might take longer to excrete medication bc kidneys are not on full function.
