Comparison of Respiratory Event Detection by a ...

01/09/2005· Whereas this study did not directly compare the PVDF sensor and a traditional thermistor, the results suggest that the PVDF sensor is likely to be a more sensitive instrument for detecting changes in airflow during sleep compared with traditional thermal devices. The PVDF sensor does not show flow plateaus during airflow limitation. However, easily identifiable changes in the PVDF signal …

Thermistor Research Papers -

Traditional temperature biofeedback uses the contact sensor of a thermistor to measure one’s finger surface temperature. The goal of this study is to discover new valid sensors for temperature biofeedback. Sixteen healthy young adult volunteers (± years old) practiced cognitive imagery muscle relaxation with three kinds of temperature sensors (thermography imaging, thermistor, and ...

AASM Criteria for Scoring Respiratory Events: Interaction ...

A potential limitation of the current study is that it is retrospective, using data that were collected under the protocols in place in a routine adult diagnostic sleep laboratory, and, as a result, no special effort was made to correct poor-quality signals in either thermal or nasal pressure sensor. However, this could also be construed as an advantage because the study is more likely to be ...
