Questions and Answers
What is the minimum number of naps to be performed during the MSLT study? - ANS-4
Paradoxical breathing is defined as? - ANS-respiratory effort from the chest and
abdomen in oppostion to each other.
What is the goal of the MSLT? - ANS-to measure the speed of falling asleep in a sleep
inducing environment and in the absence of competing stimuli.
The average duration for an apneic event is? - ANS-20-30 seconds
CPAP pressures set too low may result in? - ANS-continued hypoventilation and
hypoxemia.
Epileptiform activity during the PSG is? - ANS-best displayed utilizing additional EEG
channels.
When determining the proper CPAP mask size for the patient it is important to check
that? - ANS-leaks are not present
The patient position that usually requires a higher CPAP pressure is? - ANS-supine
MSLT studies performed after nocturnal recording should begin? - ANS-1.5-3 hours
after the end of the nocturnal recording
When performing a CPAP titration you would increase the pressure if? - ANS-snoring is
heard
The objectives of CPAP/BiPAP/AP are all of the following except? - ANS-the
improvement of total lung capacity
When snoring effects sleep onset during MSLT, what monitors should be utilized? -
ANS-measures of respiratory flow/ respiratory channels
The most frequently observed cardiac arrhythmias seen with obstructive sleep apnea
during the PSG is? - ANS-bradycardia and tachycardia
Effective treatment with CPAP is evidenced by all of the following except the? - ANS-
restoration of arousals
, The initial pressure setting for CPAP titration should be? - ANS-3-5 cm H2O
In order to evaluate the occurrence of REM during an MSLT, the recording should
continue? - ANS-15 min after the first epoch of sleep
A complete absense of effort in respiratory monitoring channels indicates? - ANS-a
central apnea event
During the NPT, penile circumference changes are monitored using? - ANS-mercury
filled strain gauge electrodes
A desaturation during an apnea/hypopnea can be related to all of the following except? -
ANS-chin movement
The patient effectively treated with CPAP for the first time must be observed for the
undesirable occurrence of? - ANS-severe hypoxia or hypercarbia
Supplemental O2 may be required with CPAP for the following disorders? - ANS-
chronic lung disease and congestive heart failure
During a respiratory event, is it possible to observe all of the following except? - ANS-
ringing in the ears
CPAP pressures set too high may cause? - ANS-intolerance of the treatment and
triggering of central apneas
A specific scenario for a clinical MSLT could be? - ANS-lights out, no sleep recorded,
end nap in 20 minutes
Snoring seen with obstructive sleep apnea syndrome is - ANS-loud and alternating with
periods of silence
To prepare properly for a full night PSG recording in a patient who has suspected sleep
terrors and sleepwalking, some of the following precautions might be considered - ANS-
remove anything potentially hazardous from the bedroom and cover glass
windows/mirrors with heavy drapes/ cloth
The goal of raising the head of the bed in cases of suspected sleep related esophageal
reflux is to - ANS-reduce the possibility of pulmonary aspiration
One of the contraindications for the use of CPAP is - ANS-communication between the
nasal pathway and cerebrospinal fluid
