Scoring and Sleep Stage C (p. D19) Flashcards
Three electrodes should be placed to record chin EMG. Where are they supposed to go?
One electrode midline 1 cm above the inferior edge of the mandible
Two electrodes 2 cm below the inferior edge of the mandible and 2 cm to the left and right of the midline.
Why are leg and arm EMG’s monitored?
To monitor for PLMS and/or RLS.
Why are intercostal EMG’s monitored?
To measure respiratory effort.
During a sleep study, tachycardia is a heart rate over ___ BPM.
90
During a sleep study, a heart rate below ___ is considered bradycardia for anyone over __ years of age.
40 or below is considered bradycardia for anyone over 6 years old.
Narrow complex tachycardia is a rhythm lasting # consecutive beats at a rate of greater than _#__ and a QRS duration of less than # msec.
3 consecutive beats, 100 beats per minute, and less than 120 msec.
What is the preferred device used for identifying apnea during a diagnostic study?
Oronasal thermal airflow sensor
What is the preferred device used for identifying hypopnea during a diagnostic study?
Nasal pressure transducer
What are three devices that can be used to monitor apnea during a diagnostic study? (These devices are not preferred. They’re back-up devices.) (x3)
Nasal pressure transducer
Respiratory inductance plethysmography sum (RIPsum)
Respiratory inductance plethysmography flow (RIPflow)
What are three devices that can be used to monitor hypopnea during a diagnostic study? (These devices are not preferred. They’re back-up devices.) (x3)
Duel thoracoabdominal RIP belts
Respiratory inductance plethysmography sum (RIPsum)
Respiratory inductance plethysmography flow (RIPflow)
During positive airway pressure titration, what should you use to identify apneas and hypopneas?
The PAP device flow signal
What should you use to monitor respiratory effort? (x2)
Esophageal manometry (balloon) or duel thoracoabdominal RIP belts
When using a pulse oximeter to monitor O2sat, the maximum acceptable signal averaging time is less than ___ seconds at a heart rate of ___ beats per minute.
3 seconds, 80 beats per minute.
What should you use to monitor snoring?
An acoustic sensor (microphone), piezoelectric sensor, or nasal pressure transducer.
What should you use to detect hypoventilation during a diagnostic study?
Should you do this during a PAP titration?
Arterial PCO2, transcutaneous PCO2, or end-tidal PCO2
You can do this with PAP titration or without it.
