Syllabus for PSG-103

POLYSOMNOGRAPHY SCORING


COURSE DESCRIPTION

Polysomnography Scoring provides a solid foundation in the principles, techniques, and concepts related to polysomnographic scoring. The course covers the fundamental concepts of sleep staging, arousal recognition and scoring, and event scoring for respiratory, limb, and cardiac events.  

The course outlines the standard scoring practices currently in use. Clinical judgment is always necessary, both when scoring and interpreting polysomnograms. Therefore, you are encouraged to stay abreast of changes in the field, including updated practice parameters and newly published standards and guidelines. The quality of the interpretation of the polysomnogram you record has much to do with your ability to understand, and accurately score, the recording.

COURSE OBJECTIVES

After completing this course, you should be able to:

  1. Identify normal adult and pediatric wake and sleep EEG patterns.
  2. Identify and describe normal and abnormal sleep architecture.
  3. Identify and score:
  1. adult and pediatric sleep/wake stages.
  2. arousals and awakenings.
  3. adult and pediatric respiratory events and respiratory effort-related arousals and awakenings.
  4. movements and event-related arousals and awakenings.
  5. cardiac events.
  1. Identify and document unusual occurrences including REM sleep behavior disorder, rhythmic movement disorders, seizure activity, alpha-delta sleep, and drug-induced EEG spindles.
  2. Perform the calculations required to reduce scored data according to standard PSG reporting parameters.
  3. Create and verify the accuracy of a PSG technical report.
  4. Define the scoring process and reporting parameters used for MSLT/MWT testing.
  5. Define the scoring processes and reporting parameters used for portable monitoring procedures.

ASSESSMENT METHODS

For your formal work in the course, you are required to participate in online discussion forums, to submit scoring assignments and reports, to take a proctored midterm examination, and to complete a final project. See below for more details.

Consult the course Calendar for due dates.

Discussion Forums

Polysomnography Scoring requires you to participate in ten (10) graded discussion forums worth 16% of your course grade. There is also an ungraded but required Introductions Forum in Module 1.

Communication among fellow students and with the mentor is a critical component of online learning. Participation in online discussions involves two distinct activities: an initial response to a posted question (discussion thread) and subsequent comments on classmates' responses. Meaningful participation is relevant to the content, adds value, and advances the discussion. Comments such as "I agree" and "ditto" are not considered value-adding participation. Therefore, when you agree or disagree with a classmate, the reading, or your mentor, state and support your agreement or disagreement. You will be evaluated on the quality and quantity of your participation. Responses and comments should be properly proofread and edited, professional, and respectful.

Deadlines for posting discussion topics are given in the course Calendar.

Click the link below for an evaluation rubric that will aid in the grading of online discussion forums.

Scoring Assignments

Each module concludes with one or more scoring assignments or reports, collectively worth 44% of your course grade. Scoring assignments and reports entail working with sample sleep studies that you will download and save to your computer, along with their respective scoring spreadsheets.

Midterm Examination

You are required to take a proctored midterm examination worth 15% of your course grade. You must take the midterm online using the College's Online Proctor Service. Please refer to the "Examinations and Proctors" section of the Online Student Handbook (see General Information tab in the course Web site) for further information about scheduling and taking online exams and for all exam policies and procedures. You are strongly advised to schedule your exam within the first week of the semester.

The midterm exam is two hours long and covers all topics and material from Modules 1–5 of the course. It consists of multiple-choice questions based on the lecture notes and assigned reading.

Online exams are administered in the Examinations section of the course Web site. Consult the course Calendar for the official dates of midterm exam week.

Final Project

For your final project, you will stage, score, and report on 200 epochs of an adult PSG study. The final project is worth 25% of your course grade.

Please see the Final Project section of the course Web site for further details about the project. Consult the course Calendar for its due date.

GRADING AND EVALUATION

Your grade in the course will be determined as follows:

  • Scoring assignments and reports (11)—44%

  • Online discussions (10)—16%

  • Midterm exam (proctored, modules 1–5)—15%

  • Final project—25%

All activities will receive a numerical grade of 0–100. You will receive a score of 0 for any work not submitted. Your final grade in the course will be a letter grade. Letter grade equivalents for numerical grades are as follows:

STRATEGIES FOR SUCCESS

First Steps to Success

To succeed in this course, take the following first steps:

Study Tips

Consider the following study tips for success:

ACADEMIC INTEGRITY

Students at Thomas Edison State College are expected to exhibit the highest level of academic citizenship. In particular, students are expected to read and follow all policies, procedures, and program information guidelines contained in publications; pursue their learning goals with honesty and integrity; demonstrate that they are progressing satisfactorily and in a timely fashion by meeting course deadlines and following outlined procedures; observe a code of mutual respect in dealing with mentors, staff, and other students; behave in a manner consistent with the standards and codes of the profession in which they are practicing; keep official records updated regarding changes in name, address, telephone number, or e-mail address; and meet financial obligations in a timely manner. Students not practicing good academic citizenship may be subject to disciplinary action including suspension, dismissal, or financial holds on records.

 

Academic Dishonesty

Thomas Edison State College expects all of its students to approach their education with academic integrity—the pursuit of scholarly activity free from fraud and deception. All mentors and administrative staff members at the College insist on strict standards of academic honesty in all courses. Academic dishonesty undermines this objective. Academic dishonesty can take the following forms:

Please refer to the Academic Code of Conduct Policy in the College Catalog and online at www.tesc.edu.

 

 

Plagiarism

Using someone else’s work as your own is plagiarism. Thomas Edison State College takes a strong stance against plagiarism, and students found to be plagiarizing will be severely penalized. If you copy phrases, sentences, paragraphs, or whole documents word-for-word—or if you paraphrase by changing a word here and there—without identifying the author, or without identifying it as a direct quote, then you are plagiarizing. Please keep in mind that this type of identification applies to Internet sources as well as to print-based sources. Copying and pasting from the Internet, without using quotation marks and without acknowledging sources, constitutes plagiarism. (For information about how to cite Internet sources, see Online Student Handbook > Academic Standards > “Citing Sources.”)

Accidentally copying the words and ideas of another writer does not excuse the charge of plagiarism. It is easy to jot down notes and ideas from many sources and then write your own paper without knowing which words are your own and which are someone else’s. It is more difficult to keep track of each and every source. However, the conscientious writer who wishes to avoid plagiarizing never fails to keep careful track of sources.

Always be aware that if you write without acknowledging the sources of your ideas, you run the risk of being charged with plagiarism.

Clearly, plagiarism, no matter the degree of intent to deceive, defeats the purpose of education. If you plagiarize deliberately, you are not educating yourself, and you are wasting your time on courses meant to improve your skills. If you plagiarize through carelessness, you are deceiving yourself.

Disciplinary Process

First-time incidents of academic dishonesty concerning plagiarism may reflect ignorance of appropriate citation requirements. Mentors will make a good faith effort to address all first-time offenses that occur in courses. In these cases, the mentor may impose sanctions that serve as a learning exercise for the offender. These may include the completion of tutorials, assignment rewrites, or any other reasonable learning tool including a lower grade when appropriate. The mentor will notify the student by e-mail. Decisions about the sanctions applied for subsequent plagiarism offenses or other violations will be made by the appropriate dean’s office, with the advice of the mentor or staff person who reported the violation. The student will be notified via certified mail of the decision. Options for sanctions include:
