NUR 211 EXAM #4 – VENTILATORS
QUESTIONS AND CORRECT
ANSWERS
the baseline FiO2 on a ventilator is 40% and will move up by 10% with 100% being the max amount a
patient can receive
pressure support ________________ the work of breathing by finishing the patient's spontaneous
breath on _________________ ANSW✅✅decreases; inspiration.
when you have a spontaneous breath, pressure support will finish it for you on inspiration if needed.
PEEP helps to improve arterial oxygenation by keeping what open on expiration? ANSW✅✅the
alveoli
what are the two types of ventilation? ANSW✅✅Negative pressure and positive pressure
what is negative pressure? ANSW✅✅the iron lung.
It sucks negative pressure from the thoracic cavity. Was once used for conditions like polio, but is
not used any longer.
how does positive pressure work? ANSW✅✅it pushes air into the lungs.
basic ventilation settings: ANSW✅✅there is 1 big screen that is separated into two smaller
screens.
the bottom is what the vent is doing for the patient, and the top is how the pt. is handling it
respiratory rate definition: ANSW✅✅how many breaths/min the patient receives.
make sure to monitor what the rate of the vent is and what the patient's rate is
, what is TV? ANSW✅✅tidal volume.
the amount of air that is breathed in
what is FiO2? ANSW✅✅oxygen in %
it can be set in either volume or pressure modes
______________ mode gives a preset amount of TV - but a patient in this mode needs to have lungs
that are able to expand and receive that volume ANSW✅✅volume mode.
May be given for COPD or uncomplicated pneumonia
true/false - volume modes give a preset volume and rate ANSW✅✅true
with any volume mode, you will have FiO2 but can add in what 2 pressure components?
ANSW✅✅PEEP and pressure support
volume modes:
CMV (controlled mandatory ventilation) gives a preset volume and rate but the patient will never
_______________ the ventilator ANSW✅✅overbreathe.
May be used in the OR or in paralysis cases
an example of CMV: ANSW✅✅the preset RR is 14 breaths/min with a preset TV of 500 mL.
For each of those 14 breaths, the patient will receive 500 mL and never overbreathe the vent
what is ACV (assist-control ventilation)? ANSW✅✅gives a preset rate and volume, but *the
patient can over breathe the vent*
