POSM 104 - Polysomnography I

(TP/SS only) CE

An introduction to the theory and practice of polysomnography. Preparation of patients and equipment, as well as equipment selection, for the desired testing procedures will be discussed. Instrumentation and refinement of tracings via EEG, EOG, ECG, and EMG will be introduced. PREREQUISITE(S): Consent of department. COREQUISITE(S): POSM 102 , POSM 103 , and POSM 105 . Two hours lecture, three hours laboratory each week. Formerly PO 104.

3 semester hours

Course Outcomes:
Upon course completion, a student will be able to:

  • Explain principles of infection control within the health care setting.
  • Explain principles of function, handling, site selection and placement of electrodes, electrolytic substances, and fixatives for EEG, EOG, ECG, and EMG.
  • Alter polysomnography procedures based on patient’s age, culture, or special needs.
  • Prepare polysomnographic equipment both before and after polysomnogram.
  • Summarize the process of measuring the electromechanical functions of the human body, including extra-cellular potentials created by cardiac, brain, muscle, and integumentary cells.
  • Explain the frequency and voltage characteristics of EEG< EOG< ECG< and EMG.
  • Explain operative principles of airflow and effort monitors, oximeters, and capnometers.
  • Explain impedance measurements, impedance meters, signal calibration, electrical baseline, and mechanical baseline.
  • Explain the principles of signal calibration as they pertain to digital and analog recording systems and substandard signal calibrations.
  • Select equipment, data acquisition parameters, and therapeutic modalities based on information obtained from patient assessment and review of medical record.
  • Manipulate amplifier settings to maintain data integrity of calibrations and bio-cals.
  • Prepare sample montages indicating the channel derivation and how they differ for referential and bipolar recordings.
  • Create a polysomnographic recording montage.
  • Distinguish between artifact and physiological signals on polysomnographic recordings.
  • Differentiate between life threatening and non-life threatening dysrhythmias.
  • Explain the principles of application of PAP and oxygen devices for sleep related breathing disorders.
  • Assess patients and their medical records to identify accurate sleep protocols and special patient needs during the polysomnogram.
  • Measure vital signs of patients.
