Which of the following medications would be most helpful to the patient? -
answer✔✔Romazicon (Flumazenil)
In preparation for ventilator weaning the physician requests a VD/VT ratio assessment. Which of
the following is needed to determine the deadspace-tidal volume ratio? - answer✔✔Arterial
blood gases and capnographic data
Which of the following alarms would be most important for a patient receiving positive pressure
ventilation by a pressure-cycled ventilator? - answer✔✔Low volume
- If patient is on a pressure cycle ventilator that means the ventilator is going to deliver a certain
pressure regardless of how much volume is achieved. Thus the most important alarm is the low
volume alarm.
Which of the following would be most effective at resolving a humidity deficit for a patient who
is intubated with an 8.0-mm endotracheal tube? - answer✔✔Concha Heated Humidifier

cmH2O
What would occur on a time-cycled ventilator with a fixed rate if the inspiratory flow rate were
increased? - answer✔✔increase in tidal volume
-On a time-cycled ventilator inspiratory time is predetermined. So, if the flow rate is increased
while the mandatory rate is unchanged, the result would be an increase in tidal volume.
Which of the following is the most significant complication of bronchoscopy? -
answer✔✔laryngospasms
