Cleveland Family Study
17.8.6 Step 6: Attach Thermistor
These are made of temperature sensitive wires which are positioned directly in the flow of air.
- Thermistor should be placed under nasal area on participant’s upper lip so that the three-thermistor beads are exposed to the patient’s nasal and oral airflow. See cannula attachment before attaching thermistor.
- Secure in place by looping wire around ear and taping wires over cheek. The beads should not touch the lips, skin or nasal mucosa membranes.
Note: The thermistor is sensitive to displacement or moisture. Before leaving, show the participant (in a mirror) and/or a family member how the thermistor should be positioned. Show the participant how to re-adjust this, if needed. Warn him to try and keep his upper lip dry. Nighttime beverages should be consumed through a drinking straw.
