what type of trigger does the 840 have?
ideally, where do u want to keep the cuff pressure
< 25 cmh20 water pressure
best measure of muscle strength
< -20 NIF
what vent changes will you make to increase co2
- in volume ventilation:
- dec RR
- dec VT
- in pressure vent:
- dec pressure
- add deadspace (every 6in = 50cc's)
if someone has a ABG of
inc fio2 or peep
if pt is off ventilator for an hour weaning and hr increases from 86 to 106 and develops PVC's, what would u do?
- increase fio2 for PVC's
- put the pt back on vent
when is PS activated in what kinda modes?
any mode w/ a spontaneous breath
what does CMV stand for
continuous/controlled mechanical ventilation
if pt has a 1:1.2 ratio and the pt appears uncomfy, what could u do to correct?
increase flow (short the itime, longer etime)
by increasing flow you will also increase
if u change vent circuit and the pt exhaled vt is 300 cc's less than set, what would u do
- take pt off vent and bag pt
- and then check for leaks
what would cause a high pressure alarm
- tension pneumothorax
- water in the tube/circuit
- kink in circuit
- mucus plugs
formula for RSBI
f/vt in liters
what would u do?
dec rr or vt so CO2 will rise
if u have a severe lung term COPD pt with these ABGS what would u do
if somebody is in SIMV, and they appear alil uncomfy but vital signs are stable and pt keeps getting a low exhaled vt on spont breath, what can u do to correct that?
if the flow sensitivity is set too sensitive, what will happen?
auto cycle (keep triggering) w/o the pt
medical patients vt
surgical patients vt
if u increase someones peep from 3 to 9, what will you watch?
- peak pressure
- bp (increasing peep will decrease bp)
if u did a spontaneous weaning parameter on a pt and results are
-14, vt of 500, vc of 1600, nif of -30
- wean if u haven't started weaning
- or extubate
what is the formula of static compliance
know how to calculate
if u have a 80 kg pt on these settings
simv of 12, 400, .50, 15 ps
and indicating that theyre not getting enough air, what would you do?
pt in the ICU with
simv of 12, 750, .50, 10 of ps
w/ ABG's of
what would you recommend to do to the pt?
how would u classify this ABG
resp acidosis w/ moderate hypoxemia
how would you fix the problem?
- increase RR
- increase FIO2 or peep
does the avea have a internal nebulizer?
does the avea have a PRVC
how do you get ppl pressure and a compliance on the 840?
if u put a pasemear valve (speaking valve) on a pt's tube, what do u have to do to the patient's cuff?
DEFLATE the cuff!!!!!!
if u put a pasemear valve (speaking valve) on a pt's tube, and you don't deflate it, what will happen to the patient and their lungs?
pt WONT be able to EXHALE
pt's lungs will OVER INFLATES until they pop (barotrauma)
is VC+ a mode available on the 840?
VC+ acts like (which mode)?
if you are looking for a leak on a ventilator, where are some places will you look
- water traps
when u turn on the 840, what do u do? what screen will pop up?
- open atmosphere (cap off)
- new pt or same pt screen
if patient is intubated with ett and u want to decrease their work or breathing (on vent and NOT on the vent)
- give PS
- CUT THE TUBE (will decrease resistance)
where do you auscultate after intubation? and what should u do to verify?
- then lungs
- check c02
- cxr (3cm above carina)
what would u wanna take a long on a road trip?
if youre doing a circuit change, what do you remove first?
if youre giving a MDI through the 840 you can give an ins pause, manuel inspiration OR?
pause time (ppl time)
does the 840 have a sigh
if youre doing trach care for a disposable shilley trach, what are the things you need
- inner cannula
NO NEED FOR A CLEANING BRUSH (only w/ a non-disposable trach)
when is pressure sensitivity active on the avea?
when the nebulizer is on
if you have someone set on
simv of 6, 600, .40, 5 of peep
you want their APNEA settings on what?
- 20 seconds
- 100% fio2
- rate of 10 (no less than 10)
what are some hazards on a in-line suction catheters
- suction button may not be locked
- pt may self extubate
- suck vt away
(peak pressure may rise; low vt)
