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. [Show More]
