PSG 2411 FINAL EXAM SET

PSG 2411 FINAL EXAM SET when performing a MWT a 4-trial _____ minute protocol is recommended - 40 Excessive daytime sleepiness is defined as: - sleepiness occurring in a situation when one would be expected to be awake and alert _____ SOREMPS seen on an MSLT nap is indicative of narcolepsy - 2 Reduced sleep latency during the MSLT is defined as a mean sleep latency - less than 8 minutes You have achieved a good titration when you see that the RDI is _____ per hour (or reduced by 50% if the baseline RDI was 15) for a period of least 15 minutes at the selected pressure and within the manufacture's acceptable leak limit. - 10 Which of the following is an accepted response to continued snoring on CPAP? - increase the pressure by 1 cm/H20 which of the following MUST be monitored to determine PAP therapy efficacy? - apnea/hypopnea index Relative to indications, complications, and treatment effectiveness, CPAP is equivalent to which of the following? - EPAP which of the following is an accepted response to continued snoring on CPAP? - increase the pressure by 1 cm/H20 The MSLT protocol consists of _____ nap opportunities, each separated by ___ hours - 5; 2 VAPS therapy is approved for what patients? - COPD Neuromuscular disease Restrictive Lung disease What does BPAP ST mode have that BPAP S mode does not? - Back up rate The following RECOMMENDED guidelines, which of the following would be an appropriate time to end an MWT trial? - 3 consecutive epochs of stage N1 which of these is true regarding a Maintenance of Wakefulness Test? - All of the above what is the MOST likely consequence of the over titration of PAP? - increased arousals what is the most effective method for improving adherence to therapy? - Early intervention to address patient complaints the sleep latencies of MSLT naps are as follows: 6 min, 7 min, 1 min, 6 min, 10 min. what is the mean sleep latency? - 6 minutes the clinical multiple sleep latency test (MSLT) is continued for 15 minutes after the first: - epoch of any stage of sleep Begin BPAP at EPAP ____ cm/H20 or the ____ level at which obstructive apneas was eliminated; set IPAP ____ cm/H20 higher - 4, CPAP, 4 in changing from CPAP to BPAP, the EPAP should be set at the pressure that resolved the obstructive events and the IPAP should be at least ____ cm H20 higher - 4 A tracing taken from BPAP titration and showed that the patient has continuous obstructive apneas in a 9-minute period. The patient is one BPAP of 12/8 cmH20. What would you recommend? - BPAP 13/9 During a bilevel PAP titration with a setting of 17/13 cmH20, the patient exhibits 2 obstructive apneas over the course of 7 minutes. Neither of these events is associated with an arousal. The technologist's BEST immediate response would be to: - Increase IPAP and EPAP During a sleep study, the technologist using ASV should increase EPAP when which of the following are present? - Obstructive apneas During a CPAP titration on a 30-year-old-patient, the sleep specialist notes an initial SpO2 of 96% but early in the titration, there are periods of a drop in peak signal of the PAP device flow by as much as 90%, accompanied by increasing thorabdominal paradoxical movement. The CPAP pressure is set at 15 cmH20 for 10 minutes without relief of the obstructive periods. The sleep technologist should do which of the following? - Switch the patient over to bilevel ventilation in spontaneous mode During a titration study the patient's apneas are eliminated at 10cm/H20 but hypopneas and snoring continue at 16 cm/H20. According to recommended guidelines, the appropriate pressures to begin a bilevel titration is: - IPAP 14
