RRT Questions, Mechanical Ventilation Flashcards
What is a normal MEP?
When is it so low you need to intubate?
160 cm H2O
40 cm H2O
Initial settings: Resp rate
8-12 breaths per minute.
Initial settings: FiO2
40-60%.
If pt is currently on O2, match current FiO2
What is the rule for eliminating wrong vent settings?
- FiO2: 40-60%
- Resp rate: 8-12 breaths per minute
- Mode (Do not eliminate by mode alone)
Use this mode for head trauma patients.
Control mode
Use this mode for patients requiring high FiO2, High PEEP, high PIP, and low PaO2.
Pressure Control Ventiation.
In PRVC (VC+), the desired rate and tidal volume are set equal or greater than ___.
The resistance.
No normalize a high PaCO2…
- First, ___ the ___.
- Second, ___ the ___.
- Third, ___ the ___.
First, remove deadspace.
Second, increase resp rate.
Third, increase tidal volume.
When a patient is initially ventilated, you should first place the patient in a ___ position.
After that, the best positions are ___ or ___.
Supine
Semi-fowler’s.
For patients with asthma disregard normal vent settings. Tidal volume should be set to ___.
Resp rate should be set at ___.
Consider permissive hypercapnea.
4-6 mL/kg
10-12 breath per minute.
Consider permissive hypercapnea for asthma patients.
While doing IPPB, your patient starts complaining about tingling fingers. What should you do?
Instruct the patient to do an inspiratory hold for 1-3 seconds.
How should you set an incentive spriometry goal?
It should be half of the pre-op vital capacity. (If the patient is not getting anywhere close to that goal, then lower it.)
While doing IPPB, the machine isn’t cycling off. What’s wrong?
Check for a leak somewhere.
Cuff leak?
Fenestrated trach tube? Inflate the cuff.
