Grade Determinations

Medical Instrument Technician (Polysomnography) GS-6 :

Experience: At least 1 year of experience comparable to the next lower grade level which demonstrates the knowledge, skills, abilities, and other characteristics related to the duties of the positions to be filled. In addition, the candidate must demonstrate the following KSAs:

Demonstrated Knowledge, Skills, and Abilities (KSAs):
1. Knowledge of standard, computerized polysomnographs for recording continuous all night physiological data including EEG, EOG, EKG, EMG and respiratory parameters.
2. Knowledge of standard devices such as oximeters, respiratory effort devices, nasal pressure devices, thermistors, thermocouples, continuous positive airway pressure (CPAP) machines, and laboratory computers including the ability to calibrate and operate the equipment and recognize and eliminate recording artifacts.
3. Knowledge of medical terminology and medical record organization to review medical records, sleep study orders, consent forms, medical charts, etc.
4. Knowledge of polysmnographic procedural protocols (including overnight sleep studies, MSLT, MWT, PAP, etc.).
5. Knowledge of basic anatomy and physiology and the international 10-20 electrode placement system in order to conduct the sleep studies.

Certification: No certification or registration is required at this level. Basic Cardiac Life Support (BCLS) certification is desirable.

Assignment: Polysomnography (PSG) Technicians at this level perform a full range of standard, routine examinations including overnight sleep studies, MSLT (Multiple Sleep Latency Test), MWT (Maintenance of Wakefulness Test), and PAP (Positive Airway Pressure Titration).


Medical Instrument Technician (Polysomnography) GS-7:

Experience: At least 1 year of experience comparable to the next lower grade level which demonstrates the knowledge, skills, abilities, and other characteristics related to the duties of the positions to be filled. This would be experience which provided the individual with the knowledge, skills, and abilities to independently conduct difficult but standardized polysomnography examinations. In addition, the candidate must demonstrate the following KSAs:

Demonstrated Knowledge, Skills, and Abilities (KSAs):
1. Knowledge of CPAP function and operation to select and fit appropriate PAP patient interface devices.
2. Ability to independently titrate and document PAP level to achieve therapeutic goals.
3. Knowledge of indications, complications, and contraindications of CPAP therapy.
4. Knowledge of Bi-Level pressure titrations.
5. Ability to recognize changes seen during the PSG tracing and identify all stages of sleep. This includes the ability to score and analyze sleep stages in clinical polysomnography recordings.

Certification: No certification or registration is required. Basic Cardiac Life Support (BCLS) certification is desirable.

Assignment: At this level the Polysomnography Technician performs a full range of standard, but complex, polysomnography examinations with responsibility for properly and accurately calibrating all instruments prior to the beginning of the PSG tracing and selection of appropriate electrode montages and sensitivity and filter settings to elicit the best possible tracings. They independently determine the need for CPAP during all night sleep studies for sleep apnea. They may administer nerve conduction velocity tests.


Medical Instrument Technician (Polysomnography) GS-8

Experience: At least 1 year of experience comparable to the next lower grade level which demonstrates the knowledge, skills, abilities, and other characteristics related to the duties of the positions to be filled. This would be experience which provided a knowledge of the more complex procedures as well as knowledge of the uncommon and/or rare sleep disorders. In addition, the candidate must demonstrate the following KSAs:

Demonstrated Knowledge, Skills, and Abilities (KSAs):
1. Advanced knowledge or the International Classification of Sleep Disorders and the ability to recognize uncommon and/or rare sleep disorders.
2. Ability to summarize and report polysomnographic data in narrative form.
3. Knowledge of event characteristics (e.g., respiratory, cardiac, sleep stage, seizures, etc.) and ability to take appropriate action.
4. Ability to provide briefings and orientation to hospital staff including physicians.

Certification: No certification or registration is required. Basic Cardiac Life Support (BCLS) and Advanced Cardiac Life Support (ACLS) certifications are also desirable for employees at this level.

Assignment: This represents the full performance level. At this level Polysomnographic Technicians are able to interact fully with the patient and physician to diagnose sleep disorders including those that are uncommon or rare. They are able to conduct full sleep studies including overnight studies and evaluate the relationship of events, sleep stages, and possible medical conditions which influence or result from events occurring during sleep. They anticipate problems likely to occur during the sleep study and prepare for such situations, make changes in established procedures, or recommend alternative courses of action. They are able to mentor lower graded technicians.
