Mechanical Ventilation 3B Flashcards
If the oxygen index is ___, it’s time to consider ECMO.
40+
What’s the most common mixture of Heliox?
You might also see this mixture.
80:20. (That’s 80 parts He and 20 parts O2)
70:30
(They don’t really need O2 they just need to ventilate better. So don’t think of getting O2 in, think of getting He in.)
When would you want to pronate the patient?
FiO2 greater than ___.
PEEP greater than ___.
Patients with ___ and who have large ___ and not ___ well.
FiO2 greater than 60
PEEP greater than 12
ARDS patients with large shunts and not oxygenating well.
When you are taking care of a post-op patient and you see he’s really somnulant, consider ___.
NIV
What are good initial settings for NIV?
10/5 plus or minus 1-2
IPAP should be double EPAP.
NIV can be used as part of end of life care. True or false?
True.
In asthma patients, NIV can increase ___, resulting in ___.
NIV can increase FRC, resulting in air trapping.
To do independent lung ventilation, you need a special tube. There’s three names for this tube. What are they? (x3)
Carlens tube
Endobronchial tube
Double lumen tube
When you’re doing independent lung ventilation, what do you have to remember about setting initial settings?
When you set the tidal volume, you have to set it to half what you would normally give.
When considering NIV, think about the risk of ___. This is a contraindication.
Aspiration risk (Including excessive secretions)
Name relative contraindications to NIV

You should transition from NIV to mechanical ventilation if the pH is less than ___.
7.25
You should transition from NIV to mechanical ventilation if the respiratory rate is greater than ___.
35 bpm
You should transition from NIV to mechanical ventilation if the PaO2 is less than ___.
PaO2 >40
