,The polysomnography sleep laboratory is fully scheduled for several weeks. The
physician wants to know if there is another option to determine if a patient has sleep
apnea. What should be recommended?
a. Overnight pulse oximetry
,b. Nasal air flow monitoring
c. Holter monitoring for 48 hours
d. Chest-wall and abdominal-wall impedance comparison
Give this one a try later!
Overnight pulse oximetry
Explain:
A. Overnight pulse oximetry can be used to screen patients with suspected
obstructive sleep apnea. The patient's oxygen saturation is found to
decrease during apnea episodes.
B. Nasal airflow monitoring is done only during a full polysomnography
test.
C. Holter monitoring is done to evaluate a patient with cardiac problems. A
continuous electrocardiogram recording is made, and the patient keeps an
activity journal.
D. Chest-wall and abdominal-wall movement is done only during a full
polysomnography test.
Apnea testing is ordered to determine brain death for a 75-year-old patient. An ABG
analysis prior to the apnea testing reveals a PaCO2 of 42 mm Hg. After 8 minutes of
100% oxygen administered to the carina and no respiratory movements observed, the
patient's PaCO2 is 64 mm Hg. A respiratory therapist should conclude the test
A. Is not supportive of a diagnosis of brain death
B. Is supportive of a diagnosis of brain death
C. Should be extended
D. Is inconclusive

, Is supportive of a diagnosis of brain death
Explain:
A. A PaCO2 greater than 60 mm Hg or an increase in PaCO2 of 20 mm Hg
or greater from baseline with no respiratory movement supports a
diagnosis of brain death.
B. A PaCO2 greater than 60 mm Hg or an increase in PaCO2 of 20 mm Hg
or greater from baseline with no respiratory movement supports a
diagnosis of brain death.
C. Criteria for a determination of brain death have been reached. It is
unnecessary to extend the test for a longer period of time.
D. Results are conclusive and supportive of a diagnosis of brain death.
Which of the following are true regarding bilevel positive pressure ventilators?
1. They function correctly in the presence of a leak.
2. They function as demand flow devices.
3. Exhaled gases pass through a fixed leak-type valve.
4. They provide adjustable pressure levels.
A. 1, 2, and 3 only
B. 1, 2, and 4 only
C. 1, 3, and 4 only
D. 2, 3, and 4 only
