The patient is asleep at the end of the test. The wake after sleep onset is 21 minutes. Total sleep time for this polysomnogram is how many minutes? โโ~ 480-3=477-21= Gastro-esophageal reflux is identified in the distal esophagus by a drop in the pH below what? โโ~ 4. Actigraphy is used to monitor what? โโ~ Gross body movement All of the following procedures are required for proper physiologic calibration during a routine polysomnogram: โโ~ Eyes open/close, Limb flexing, Teeth grinding, etc. The apnea/hypopnea index is reported as what? โโ~ The average number of apneas and hypopneas seen per hour of sleep.
A patient presents in the sleep laboratory with 5 year documented diagnosis of HIV that is controlled by immuno-suppressive medication. What considerations would be required to render care to the patient? โโ~ Practice Standard Precautions What is the most common treatment of obstructive hypopneas, hypopneas, etc. in children? โโ~ Adenotonsillectomy What is true regarding CPAP therapy in children? โโ~ It should include parent education, desensitization, and modeling After an all night PSG the patient asks the technologist about the results or possible diagnosis of their study what is most appropriate to tell them? โโ~ Tell the patient that the Dr. will review their study and go over the results with them. What is the BEST help to distinguish Central apneas from Cheyne-Stokes apnea? โโ~ Observe for a crescendo-decrescendo sequence in the effort channels PSG is ordered as a split-night titration. What is indication to initiate PAP therapy? โโ~ 40/2hours The presence of electrical interference can MOST EASILY be determined by:
โโ~ Decreasing the time base to 5mm/sec and counting the exact frequency. Which of the following is the MOST important reason to perform physiologic calibrations prior to performing a PSG study? โโ~ Assess function of the devices hooked up to the patient. A uniform method to protect patients and personnel against infectious disease will require: โโ~ High level disinfection of all electrodes used in a sleep study. What is the MOST appropriate way to sterilize virus-contaminated electrodes? โโ~ Bleach and Water What sleep disorder is associated with intermittent interruptions of REM sleep related atonia, and intense dream mention? โโ~ REM behavior disorder Nocturnal paroxysmal dystonia โโ~ Rare and NREM Nocturnal myoclonus โโ~ repetitive jerks of lower limbs
โโ~ Disconnected electrode input box What is the least appropriate to document? โโ~ The technologist's description of the patient's medical history During setup for a PAP titration study, a patient states that he has restless leg syndrome. The technologist should expect that the patient will have: โโ~ Difficulty initiating sleep The distance from pre-auricular crease to pre-auricular crease is 35 cm. What is the distance in cm between C3 and CZ? โโ~ 3. According to the recommended guidelines, unattended portable monitoring devices must include: โโ~ What is an example of an electrical artifact? โโ~ pulse* Which arrhythmia would require activation of the Emergency Response System? โโ~ Ventricular Fibrillation *
Kcomplexes and sleep spindles are most prevalent in what stage of sleep? โโ~ N2 * What is the minimum duration in seconds of an apnea/hyponea? โโ~ 10 seconds hyp. down 30% for 10 seconds According to recommended titration guidelines, CPAP should be increa sed after observing at least: โโ~ Which PAP interface is the best option for a patient with a nasal obstruction? โโ~ a-fib โโ~ atrial fibrillation AHI โโ~ Apnea Hypopnea Index APAP โโ~ Auto Positive Airway Pressure ASV
nCPAP โโ~ nasal continuous positive airway pressure DME โโ~ durable medical equipment EEG โโ~ electroencephalogram ECG โโ~ electrocardiogram EDS โโ~ excessive daytime sleepiness EMG โโ~ electromyogram EOG โโ~ electrooculogram; measures eye movement EPAP
โโ~ expiratory positive airway pressure EtCO โโ~ end-tidal carbon dioxide FIO โโ~ fractional inspired oxygen GERD โโ~ gastroesophageal reflux disorder HFF โโ~ High Frequency Filter Hz โโ~ Hertz IPAP โโ~ Inspiratory Positive Airway Pressure LFF โโ~ Low Frequency Filter
