 Which type of device uses selective absorption of light through blood vessels? | Oximeter |
| Which of the following substances is appropriate to use dor electrode disinfection? | Bleach |
| When a patient with OSA is treated with oxygen (without CPAP) it is: | not effective in reducing apnea frequency. |
| AASM accredicted sleep disorders centers must have: | an accessible policies and procedures manual. |
| In a standard polysomnographic hook-up, M1 and M2 are places over the: | mastoid process. |
| During physiologic calibrations, what is the minimum amount of recording time necessary for the "awake, eyes open" command? | 30 seconds. |
| Electrode impedances should be checked during the recording: | when an artifactual pattern appears |
| The gold standard method for measuring effort for diagnosing cheyne-stokes respiration is: | esophageal ballon. |
| To evaluate the residual sleepiness occurring during work activities, the Maintenance of Wakefulness Test (MWT) would be a procedure used: | to assess the ability to resist the urge to fall asleep. |
| On most sleep operating system, an inverted ECG signal may be corrected by performing all of the following maneuvers EXCEPT : | adjusting the filter setting on the ECG channel. |
| The primary factor in effective patient education requires establishing: | a rapport with the patient and acquiring trust. |
| The standard sensitivity setting used in polysomnography for recording EEG, EOG, and EMG channels is: | 50 uV/cm |
| Which of the following statements is incorrect concerning restless legs syndrome (RLS)? | RLS must be diagnosed via polysomnogram. |
| The primary mechanism of therapeutic action in the application of positive airway pressure for the treatment of obstructive sleep apnea is : | increased airway volume and area and reduced lateral pharyngeal wall thickness. |
| When should supplemental oxygen be added to the circuit during a CPAP or bi-level therapy titration study? | After CPAP or bi-level titration has corrected upper airway resistance and apneas and the patient is still desaturating below the level determined by the physician. |
| The centers for Medicare Services (CMS) approved definition of a hypopnea is an at least: | 30% reduction in airflow or effort compared to baseline lasting at least 10 seconds with a >4% desaturation. |
| Possible adverse effects with PAP therapy that would require close and frequent follow up with the sleep physician include all of the following EXCEPT: | ear infections. |
| A patient's report indicates an AHI of 62.5. The patient was set-up on an auto CPAP pressure with a setting range of 8-12 cm/H2O. The patient has been on the auto CPAP using a nasal mask for 10 days. He is now in the clinic for follow-up complaining of nasal dryness and his wife is complainig that he is still snoring. The CPAP device has compliance downloading capabilities. The most appropriate response is to: | download compliance data, suggest a heated humidifier and refit or resize his interface as needed. |
| A 65 year old patient who has been on CPAP for 2 months comes into the sleep center for a CPAP follow-up visit. This is an opportunity to : | review the patient's compliance and address complaints. |
| In order to score an arousal in REM sleep there must be an abrupt shift in EEG of at least: | 3 seconds with a concurrent increase in chin EMG lasting at least 1 second. |
| According to the AASM Manual for the Scoring of Sleep and Associated Events, the duration criteria for a significant leg movement is: | 0.5- 10 seconds. |
| An 82 year old patient undergoing an overnight polysomnogram demonstrates an absence of slow wave sleep, with minimal sleep disordered breathing. The technologist should: | note the observation and continue the study. |
| A normal appearing QRS complex without a preceding P-wave is a: | Premature Junctional Contraction (PJC). |
| A differential amplifier: | records the voltage difference between two inputs. |
| Sleep efficiency is calculated as: | Total Sleep Time/ Time in Bed x 100. |
