Exam III Flashcards
Neonates may be extubated from what rate?
10-12
A CO2 >55 what will PIP range would the RT need to achieve?
Increase the PIP to 25-30
What is the maximum PEEP therapy?
10
True or False: To support weaning we have to ensure that the problem has been solved
True
For ventilator weaning the FIO2 must decrease in increments of 2-5% to achieve what percent?
40%
What are the minimum acceptable ventilator settings for CPAP trials
PIP <25 cmH2O
RR 10-12 bpm
FIO2 .40
PEEP <5
CPAP NIV is typically started at an FIO2…
10% higher than the ventilator setting
How do you calculate the E-Time?
60/RR=TCT TI+X=TCT
On a pneumatic ventilator, the pressure manometer swings back towards the negative side. What must you do?
Increase flow
On a pneumatic ventilator, when evaluating what is set and the patient’s data you notice that they are hitting the pressure max (decrease in compliance). What does this mean?
They are in PC, if the PIP is lower than P Max they are in volume control
On a pneumatic ventilator, if the patient is constantly hitting the pmax what is their compliance?
Down
What is PAW affected by?
PEEP, PIP, I:E Ratio, Flow
How do you calculate MAP?
(PIP-PEEP)xTIxFlow
_____________________ +PEEP
60
What is a pao2 <50 and an FIO2 >60% an indication for?
PEEP therapy
Describe true statements involving PAW
-Keep PAW between 10-14
-MAP >12 may contribute to barotrauma
-It is the average pressure on the airways and lungs during a complete inspiratory and expiratory cycle
-Calculated electronically by vent
-Increasing MAP, increases oxygenation
