which of the following does not make a good candidate for bipap
hi paco2 - bc this is the reason why you are doing it, you want to use bipap for a pt w/ a high co2
stating settings for bipap are
10/5 + 02 (bc u have that low pa02, you have to add the oxygen +02)
which of the following can you adjust to lower c02
inc rr
hypoxic hypoxia increases in altitude
t/f
t
you have a cao2 not two cv02 bc it will cancel each other out
t/f
f
minimal rr for the vision
4
tidal range for a pt w/ ards
high rr and vt (5-8cc/kilo)
intentionally allowing co2 to rise
permissive hypercapnea
if you reduce the diameter by half you inc the pressure x16
pasollous law
if you have bowing in a pressure volume loop (2)
inc resistance (bowing is affecting resistance)
change in compliance the loop stands up or lays down
what type of compliance is measured w/o airflow
static compliance
(this is why you get a static compliance when you do a ins pause, bc its pausing air flow so its measured with no airflow)
low comp increases FRC
t/f
f
normal range for static compliance
40-60
tidal vol used in gas exchange
alverolar vol or ventilation
normal shunt
less than 10%
ipap and epap =
spontaneous timed mode (cpap)
pressure drops to allow for easier exhalation
c-flex
intial cpap settings for cpap
5
which is not a maximum support mode
pressure support
bc it is in conjunction w/ spont mode (the rest are maximum support) ac, pc, prvc are full support)
initial rr
10-20 bpm
when do u want to have an inital higher rr
a high co2 (to decrease co2)
head injury (by loweing co2 u are constricting blood vessels in the brain, causing less swelling)(u want to hyperventilate to about a co2 of 30-35 instead of a co2 35-45)
initial vt for a medical/disease normal pt
5-8 cc/kilo
initial wave flow in a ramp waveform
60-80
high flow rates can cause
increase peak ins pressure (pip) (faster the flow higher the pressure)
when is the pressure sensitivity on the avea activated
when the nebulizer function is active (as soon you activate the nebulizer the flow trigger turns off and the pressure sensitivity is functioning)
time cycle pressure limited ventilation is available only in the
neonatal settings (not pediatrics)
the 2 triggers are
flow and pressure
does the avea have a internal nebulizer
true - it uses its own flow
how do u activate a sigh in the avea
through the advance settings, vt under advance settings bc a sigh is part of your advance settings
all modes are on the avea except
vc+ (this is an 840 version of prvc)
all are advantages of the vision over the bipap s/t except
internal nebulizer
s/t has all of these modes
ipap, spont, and spont timed
what do u have to do when u need oxygen with the bipap s/t
you have to bleed in oxygen form an external source bc it does not connect to 50 psi
