Advanced Ventilator Modes Flashcards
regular ventilator mode
all mechanical breaths
are advanced ventilator modes mechanical or spontaneous breaths?
both
assisted ventilator breaths happen at what point during the spontaneous breath?
beginning
stacked ventilator breath
when the vent gives a breath in the middle of a spontaneous breath or during expiration
why are stacked breaths bad?
may lead to coughing/bucking and overinflated lungs/barotrauma
assist control ventilation
senses spontaneous breaths and assists them
there is a minimum breaths per min limit and will give a mechanical breath to reach it
if the patients respiratory rate is faster than the set minimum then 2
all breaths will be spontaneous
all spontaneous breaths will be assisted
if the patients respiratory rate is slower than the set minimum then 2
vent will kick in and give mechanical breath
breaths that are spontaneous will be assisted
intermittent mandatory ventilation
set minimum mechanical breaths per min
pt allowed to spontaneously ventilate between
ventilator does not sense pts breaths (could cause stacked breath)
which ventilator mode is the same as when we turn on the vent after intubation?
intermittent mandatory ventilation
synchronized intermittent mandatory ventilation SIMV
set minimum number of mechanical breaths
can spontaneously ventilate between mechanical breaths
CAN sense spontaneous breath
what does the ventilator do in SIMV mode when it does sense a spontaneous breath that would occur during a ventilator breath?
assist the breath instead of stack the breath
2 differences between SIMV and assist control
SIMV has set number of mechanical breath vs assist control has set number of total breaths per min
SIMV does not assist all spontaneous breaths, assist control does.
pressure support ventilation
no mechanical breaths
every breath is assisted
which ventilator mode does the pt need to be spontaneously breathing
pressure support
