Random 1
A extubated patient develops a partial upper airway obstruction, which causes stridor. What can the respiratory therapist do to improve the patient’s condition?
Aerosolize 11.25 mg (2.25% solution) of racemic epinephrine.
If a patient who has failed an SBT still meets the criteria for discontinuation of ventilation, an SBT should be performed every _______ hours
24
Mode on the ventilator that only gives support if the VE drops below a set value.
MMV
NIF/MIP
-20 cmH20 or more negative
An SBT should not continue for longer than _____ minutes.
120 minutes
A patient who requires prolonged ventilatory support should not be considered permanently ventilator dependent until ________ month(s) has/have passed and all weaning attempts during that time have failed.
3
Mode on the ventilator that is used for weaning where pressure is added to assist resistance of ETT and/or to "boost" tidal volumes.
PSV
VC:
>15 mL/kg of IBW
A postoperative patient, still under anesthesia, is being ventilated with VC-CMV with automode. After 2 hours, the patient is waking up and beginning to breathe spontaneously. The ventilator will respond by _____________________.
Switching to the volume support mode
How long does a tracheostomy site typically take to mature?
7-10 days
Mode used for weaning which allows spontaneous breathing in between mandatory breaths (has a sync window).
SIMV
VE
< 10 L/min
At what pressure is pressure support not high enough to contribute significantly to ventilatory support but is sufficient to overcome the work/resistance imposed by the ETT?
5CM H2O
When an alarm is activated on a ventilator, the respiratory therapist’s first priority is to ______________.
ensure adequate ventilation and oxygenation.
Patient is taken off the ventilator and is able to breathe through an aerosol with a certain O2%.
T-piece/T-bar
RSBI
<106 bpm/L
What ends inspiration in pressure support ventilation?
Flow
The initial step in the management of patient-ventilator asynchrony is which of the following?
Ventilate the patient with a manual resuscitator bag.
Mode on the ventilator that is used for weaning and uses a continuous positive baseline pressure to increase FRC.
CPAP
VT
>5 ML/kg of IBW
