1-60 L
intrapulmonary causes of resp failure
-lower airays
-alveoli
-pulmonary circulation
-alveolar capillary membrane
extrapulmonary causes of resp failure
-CNS injury
-neuromuscular disorders (MS, lou gehrig)
-thorax
-pleura
-upper airway disorder
device that provides pressure on both inspiration and expiration
BiPAP
continuous positive airway pressure
CPAP
describe difference between BiPAP and CPAP
BiPAP- has different inspiratory and expiratory pressures
CPAP- inspiratory/expiratory pressure is the same
where is the tube placed in intubation?
in trachea between vocal cords
2-3 CM ABOVE CARINA
what ensures correct placement of tube?
COLOR CHANGE (purple to yellow)
CXR
bilateral breath sounds
which vent settings are for PaCO2
rate
tidal volume
(pressure support settings)
which vent settings are for oxygenation
FiO2
PEEP
which vent setting is the size of each breath
tidal volume
what vent setting is the number of breaths per minute
rate
describe assist control vent mode (A/C)
has a set tidal volume and rate. can breathe over the rate, and get full set tidal volume with each spontaneous breath too.
describe synchronized intermittent mandatory ventilation setting (SIMV)
vent has a set tidal volume and rate. patient can breathe spontaneously in between set breaths, but tidal volume will be their own and not from the vent.
