A maximum frequency is 2.0 Hz According to RECOMMENDED guidelines, in patients who do not generate a dominant posterior alpha rhythm, stage N1 be scored when observing: Vertex waves According to RECOMMENDED guidelines, an arousal during stage R must be accompanied by an increase in submental EMG last at least: 3 seconds Actigraphy is MOST useful in the evaluation of: Insomnia An adult patient with good resolution of obstructive apneas on IPAP of 10 cm H2O and EPAP of 6 cm H2O begins having hypopneas after rolling supine. According to RECOMMENDED guidelines, what bilevel pressures would be appropriate after observing three obstructive hypopneas? IPAP 11 and EPAP 6 Calculate the AHI using the following data: Total recording time: 8.5 hours Total sleep time: 6.0 hours Obstructive apneas: 55 Mixed apneas: 27 Hypopneas: 110 Respiratory arousals: 199 32/hr Calculate the mean sleep latency based on the following MSLT sleep latency values Nap 1 20 minutes Nap 2 15 minutes Nap 3 2 minutes Nap 4 7 minutes Nap 5 20 minutes 12.8 min During a PAP titration, signal flattening in the nasal pressure monitor indicates: Flow Limitation Following RECOMMENDED guidelines, which of the following would be an appropriate time to end an MWT trial? 3 consecutive epochs of Stage N1 Indirect monitoring of oxygen level by the use of sensors that detect light wave absorption is: Pulse Ox Obstructive apnea is pediatric patients is MOST often associated with: Hyperactivity One of the MOST important roles of the recording technologist is to: Document any changes in recording parameters Oral appliance is an alternative option for patients with: Mild OSA Overcompensation for mask or mouth leaks when using auto-titrating CPAP (APAP) is MOST likely to result in: Unnecessarily high pressure Paradoxical breathing is identified by channel deflections that are: Out-of-phase in respiratory effort with airflow remaining flat Paradoxical insomnia is also called: Sleep state misperception Review of the patient medical history indicates obesity, hyperlipidemia, hypertension and insulin resistance. What syndrome would this represent? Metabolic Sharply contoured waves clearly distinguishable from the background with a duration of < 0.5 seconds occurring maximally over the central regions are: V waves The PRIMARY reason for instructing patients to clean masks daily is to: Minimize skin irritation The ability of an amplifier to cancel external interference that is common to both input signals is called: Common mode rejection The apnea hypopnea index is reported as the: Average number of apneas and hypopneas seen per hour of sleep The BEST way for the technologist to explain how CPAP helps eliminates obstructive apnea is to explain that: CPAP splints the obstructed airway open The circumferential measurement is 58 cm. What is the distance between O1 and O2? 5.8 cm The emergence of central respiratory events during PAP titration for treatment of obstructive apnea is: Complex sleep apnea The formula for calculating a PLM index is: Total PLMs/minutes of sleep x 60 The MOST common cause for insomnia in the general population is: Inadequate sleep hygiene The number of events that occur within a particular period of time is called: Frequency The rhythmicity of inhalation and exhalation involves interplay between the aorta, carotid arteries and: Brainstem The syndrome resulting from prolonged severe episodes of hypoxemia during sleep and associated with an increase in PaCO2 that worsens during sleep is: Obesity-Hypoventilation The two inferior chine electrodes are placed on the: Submentalis These MSLT results would be compatible with: Nap 1 SO 3 min Nap 2 SO 6 min Nap 3 SO 4 min Nap 4 SO 1.5 min Nap 5 SO 2 min Idiopathic hypersomnia What additional parameter would be MOST helpful to monitor when recording a patient with COPD? Capnography What instrument adjustment would BEST enhance visualization of N3 sleep? LFF .1 Hz What is needed to determine proper mask fit? The mask must be pressurized What type of calibration is defined as applying a calibration signal of known voltage to all amplifiers simultaneously, with the sensitivity and filter controls set to values used at the beginning of a study? Montage What would increase the resolution of EEG spikes and improve definition of the waveforms? Increasing sampling rate When a patient calls the sleep center complaining that pressure on their CPAP machine seems too high and is making it difficult to exhale, the BEST first step would be to: Verify correct PAP pressure with a manometer When a patient states they feel like they are suffocating and cannot get enough air when on CPAP, they are most likely complaining of: Air Hunger When airflow changes do not meet the criteria for obstructive apnea or hypopneas, respiratory effort event-related arousals can be estimated by: Flattening of the inspiratory airflow profile associated with an arousal When performing a PAP titration on a 10-year old, how many minutes of unambiguous snoring should be observed before increasing CPAP? 1 When recording a PSG on a 5 year-old, the EEG and EOG are being recorded with a sensitivity of 7 uv/mm. The technologist notes that the amplitude generated from the EEG and EOG electrode derivations is too high to clearly see the activity and causing waveforms to square off. What sensitivity adjustment would be appropriate? 10 uv/mm When reviewing a patient's medical history it is noted that one of the differential diagnoses is hypotension. Which of the following is MOST appropriate? Maintain awareness of the potential for false oximetry values When reviewing the medical history the technologist notes that a patient takes Xanax for panic attacks. The technologist should anticipate: Decreased N3 Which arrhythmia would require activation of an Emergency Response System? Ventricular Fibrillation Which is the MOST appropriate method for a sleep center to disinfect reusable PAP humidity chambers? Pasteurization Which of the following is a contraindication for CPAP therapy? Pneumothorax Which of the following is an example of bipolar derivation? Tibialis - tibialis Which of the following is the BEST method to aid in the clarification and differentiation of central versus obstructive respiratory events?
