• a patient on a mechanical ventilator with the FiO2 at 0.60 has a PaO2 of
50mmHg. How would you change the FiO2 to achieve a PaO2 of 65mmHg? -
✓✓increase to 0.78
• inverse ratio ventilation (IRV) is accomplished mainly by -✓✓extending the
inspiratory time
• given: ventilator circuit with a tubing compliance of 3 ml/cm H2O, PIP=50cm
H2O, PEEP 10cm H2O. The volume "lost" due to there parameters is _____ ml -
✓✓120
• Mr. John is being mechanically ventilated with these settings: Mode=SIMV,
f=12b/m, VT=600ml, FiO2= 50%, PEEP=0cmH2O. Auto-PEEP of 6 cmH2O is
observed, you would change the -✓✓PEEP to 5 cmH2O
• in addition to serial blood gas measurements, which of the following parameters
are used in the assessment of impended ventilatory failure? -✓✓tidal volume
max insp pressure
vital capacity
• an intubated patient is being treated with a broad-spectrum antibiotic. The
physician would like to do a culture and sensitivity sputum test. Since the patient's
cough is not strong enough to expectorate the retained secretions, you would
collect the sputum sample in a -✓✓lukens trap
• .while monitoring the ventilator, you notice that the pressure gauge goes from 0
cmH2O and then goes up and stays at 8 cmH2O throughout the expiratory phase.
Since PEEP is not in use, this observation is called -✓✓auto-PEEP
• airway resistance imposed by the ventilator circuit and ET tube can be minimized
or overcome during spontaneous breathing by -✓✓using pressure support
ventilation
, • a 31 y/o male patient has an IDW of 180 lb (82kg). He is under the effects of
anesthesia following surgery on his leg. What minute ventilation would be
appropriate as an initial setting? -✓✓8 L/min
• high levels of PEEP are better tolerated by the patient with non compliant lungs
because -✓✓the dampening effecct of the noncompliant lung results in less
pressure transmitted to the thoracic cavity
• permissive hypercapnia is a strategy in which the _____ value is allowed to go
beyond its normal limit and it is used to _____ -✓✓PaCO2; minimize ventilator-
related lung injuries
• severe hypoxemia is present when the PaO2 is less the 60 mmHg on 50% or more
of oxygen or less than 40mmHg at any FiO2 -✓✓true
• the PaO2 value reflects the amount of oxygen ____ and its clinical application is
limited in cases where hypoxia is due to severe _____ -✓✓dissolved in the plasma;
anemia
• which of the following is a strategy to decrease ventilator associated pneumonia -
✓✓change the ventilator circuit only when visibly solied
• a 36 y/o, 5ft 2ini, 50kg female is supported on a volume limited ventilator in the
post anesthesia care unit. The ventilator settings & ABG results are: SIMV rate of
8/min, VT=900mL, FiO2=40%, pH=7.50, PaCO2= 26mmHg, PaO2= 102mmHg.
Based on the blood gas results you would -✓✓reduce the tidal volume
• a patient receiving 50% oxygen from a venturi mask has a PaO2 of 45mmHg.
The patient is to be switched to a mechanical ventilator. What FiO2 would you set
to achieve a PaO2 of 60 mmHg? -✓✓0.67
• what variable begins the inspiratory phase of a ventilator breath -✓✓trigger
• Mr. Jones, a patient who has been mechanically ventilated for three weeks is now
on a high calorie diet. Which of the following can be a potential problem
associated with overfeeding during mechanical ventilation -✓✓increased carbon
dioxide production
