Activity 3E: Polly Want a Somnogram? Interpreting Polysomnograms

Rapamycin

Topic: Sleep

Part of:
Unit: ZZZZzzzWorld: Exploring Sleep

Lesson 3: Snoozin’s Not Losin’: It’s Good for You!

 

Now that students have learned about waves, frequency, and energy, it is time to put their knowledge to work! Students will investigate polysomnogram printouts (used by sleep diagnostic centers) that include multiple measurements such as the EEG (brain waves), EMG (leg movement) and EOG (eye movements) taken during an actual sleep study. Since many different bodily function measurements are recorded on the printout, students will learn to identify each line of a polysomnogram, comparing and contrasting the energy each wave represents. Students will be able to extrapolate the stage of sleep just by looking at different wave patterns!  

 

Objectives:

Students will be able to:

  • Analyze a polysomnogram to identify what each line is measuring, i.e. EEG, EKG, etc.
  • Observe a polysomnogram and identify the stage of sleep and/ or specific wave patterns, sleep disorders, etc.
  • Compare and contrast (labeled) polysomnograms of patients with unknown (unlabeled) patient polysomnograms to infer the stage of sleep and/or specific wave patterns and sleep disorders found in the unknowns.
