The purpose of an intentional mask leak is to... - Wash out CO2 and prevent rebreathing Recommended guidelines state that HSV can be considered when.... - Cheyne Stokes and central Apneas have not been eliminated. What is aerophagia? - The swallowing of air What is maxillomandibular advancement? - Treatment that involves cutting and advancing the upper and lower jaw bones; enlarging and stabilizing the posterior airway.

According to guidelines, how many Hypopneas need to occur in peds pts prior to increasing pressure? - 1 What are the AASM guidelines for supplemental O2 during PAP studies? - 1lmp during PAP titration when SPO2 is less than or equal to 88% for 5 or more minutes and in the absence of obstructive events. If a pts Apneas are fixed at 10cm, but Hypopneas and snoring still occur at 16cm, what levels of BiLevel should be used? - IPAP: 14 EPAP: 10 Which of the following can reduce the effectiveness of CPAP and why: Nasal spray, Alcohol, Anti depressants. - Alcohol: impairs arousal response which can lead to longer than normal events and severe desats. Inhibits upper airway activity What syndrome would a pt with COPD and OSA have? - Overlap syndrome What are hypoxemia and hypercapnia? - Hypoxemia: very low 02 in the blood Hypercapnia: very high CO2 in the blood. What would a patient with both hypoxemia and hypercapnia most likely be diagnosed with? - Hypoventilation What is an MWT's MOST important use? - Measure patients ability to resist the urge to fall asleep Tricyclic antidepressants, large amounts of caffeine and large amounts of chocolate have been known to trigger what? - REM sleep behavior disorder Recommended impedance for eeg and eog - 5k ohms The amount of space needed to archive digitized data is MOST impacted by? - Sampling rate Cortical activity is best described as - Spontaneous arousal Calculate the AHI based on the following data 25 obstructive apneas 5 central apneas 23 mixed apneas 15 hypopneas 48 RERAS 65 arousals 360 min of sleep - 11 According to RECOMMENDED guidelines, the minimum duration of a significant leg movement is - .5 According to RECOMMENDED guidelines, an optional parameter to include in the report for an adult polysomnogram is - Occurrence of hypoventilation during the diagnostic study in adult The respiratory event that requires oxygen desaturation and/ or an arousal as part of the scoring criteria is - Obstructive hypopnea An ECG arrhythmia commonly seen when recording PSG's, particularly in patients that have obstructive sleep apnea and cardiac disease. It can be identified by the morphology of an irregularly irregular ventricular rhythm associated with replacement of consistent P waves by rapid oscillations that vary in size, shape, and timing - Atrial fibrillation The stage that is the greatest portion of the epoch - The stage that is the greatest portion of the epoch What is the best response when a patient asks the technologist if they have sleep apnea and will need to wear a CPAP mask? - Provide the patient with educational material about sleep apnea Which of the following is the MOST LIKELY cause of a 35 minute REM latency - Untreated depression A breathing pattern characterized by at least three cycles of crescendo breathing with duration of at least 10 minutes is - Cheyne Stokes respiration An important responsibility of the scoring tech is to - Confirm accuracy of report components Which type of calibration is based on a series of patient instructions intended to verify the signal response and quality - Physiological The most important reason for performing a MWT is to - Measure the patient's ability to resist the urge to fall asleep The importance of selecting sampling rates according to RECOMMENDED guidelines is to - Minimize aliasing effect The syndrome characterized by prolonged episodes of severe hypoxemia and associated PaCO2 elevation that worsens during sleep is - Obesity hypoventilation The patient's medical history indicates the patient has been taking tricyclic antidepressants for the past 5 years. The technologist should anticipate that the patient may have an increased likelihood of - REM Sleep Behavior Disorder According to RECOMMENDED guidelines, the sampling rate to provide the optimal resolution for recording EEG in a patient with suspected nocturnal seizure is - 500Hz The electrode located 30% above the left pre-a crease is - C3 According to RECOMMENDED guidelines, four nap opportunities on a MSLT would be acceptable when the patient - Had REM on at least two nap opportunities A patient's history indicates a diagnosis of overlap syndrome. The tech can anticipate that the patient has - COPD AND OSA ACCORDING TO RECOMMENDED GUIDELINES, WHICH OF THE FOLLOWING SHOULD BE INCLUDED WHEN RECORDING PEDIATRIC PATIENTS - ENDTIDAL CO2 THE ABILITY TO REMONTAGE WHILE RECORDING ON DIGITAL EQUIPMENT IS THE RESULT OF - SYSTEM REFERENCING WHEN REVIEWING A PATIENT'S HISTORY IN PREPARATION FOR A POLYSOMNOGRAM, PHYSIOLOGIC FINDINGS SUGGESTIVE OF HYPOVENTILATION INCLUDE - HYPOXEMIA AND HYPERCAPNIA WHEN THE AMPLITUDE OF A SIGNAL EXCEEDS THE PHYSICAL LIMITATIONS OF A CHANNEL THE MOST IMPORTANT ADJUSTMENT THE TECH CAN MAKE TO OPTIMIZE WAVEFORM DISPLAY IS TO - DECREASE SENSITIVITY WHEN INTERMITTENT 60 HZ ACTIVITY OCCURS IN THE F4-M1 ELECTRODES DURING REM SLEEP THE BEST IMMEDIATE ACTION WOULD BE TO - RELY ON F3-M2 A PATIENT WITH MILD DEMENTIA BECOMES MORE CONFUSED AND/OR AGITATED IN THE EARLY EVENING. THE PATIENT IS MOST LIKELY EXPERIENCING - SUNDOWNING THE MOST COMMON METHOD TO MONITOR BLOOD OXYGEN SATURATION DURING POLYSOMNOGRAPHY IS - PULSE OXIMETRY THE MOST APPROPRIATE ACTION A TECHNOLOGIST WOULD TAKE WHEN THERE IS CONFIRMED VENTRICULAR TACHYCARDIA GREATER THAN 30 SECONDS IS - INITIATE EMERGENCY RESPONSE SYSTEM A PATIENT'S CHART INDICATES THAT THEY USE 30 L/MIN OF OXYGEN AT HOME. THE TECH NOTES THAT THE PHYSICIAN'S ORDERS FOR THE PSG SPECIFIES THE STUDY WITHOUT SUPPLEMENTAL OXYGEN AND TO ADD 1.0 L/MIN OXYGEN IF THE SATURATION IS LESS THAN 89%. THE BEST ACTION FOR THE TECH IS TO - CALL THE PHYSICIAN FOR CONFIRMATION WHICH OF THE FOLLOWING IS THE MOST LIKELY EFFECT OF ZOLPIDEM AND ZALEPLON ON SLEEP ARCHITECTURE - INCREASED SLEEP LATENCY WHICH OF THE FOLLOWING BEST DESCRIBES A REFERENTIAL MONTAGE - THERE IS POTENTIAL FOR ELECTRODE CONTAMINATION ACCORDING TO RECOMMENDED GUIDELINES, THE DEVICE THAT SHOULD BE USED TO MONITOR AIRFLOW AND DETECT APNEA DURING A DIAGNOSTIC STUDY IS - ORONASAL THERMAL SENSOR WHICH PROCESS WOULD BE AN ADEQUATE ROUTINE FOR DISINFECTING CUP ELECTRODES AFTER REMOVING ADHESIVE RESIDUE, GEL AND ORGANIC MATERIAL, AND WASHING IN WARM WATER AND MILD DETERGENT - SOAKING IN 1: 10 BLEACH AND WATER FOR 10 MIN.
