Nasal/Oral Temperature Airflow Measurement
(using a thermocouple)
Definition:
Thermocouples measure temperature changes associated with a patient’s breathing.
Typical Applications:
One common application of thermocouple-based airflow is to detect and measure sleep-disordered breathing events, such as sleep apnea.
Typical BioRadio Configuration:
- When using a thermocouple, make sure you are set to Advanced View when programming your BioRadio.
- Coupling: DC
- Range: ±18 mV
Typical Setup:
Step 1:
Mount the thermocouple between the nostrils and upper lip of the subject with the side with two prongs pointing up, one prong slightly into each nostril. Step 2:
Bend the prong on the bottom of the thermocouple around so that the tip is positioned directly in front of, but not in, the subject’s mouth. Step 3:
Tape the thermocouple in place with its wires running over the ears and behind the head.
