Thermistor Respiratory Monitor ECE 4760

There are many other medical devices that use thermistors to monitor the human body, mostly for the purpose of sleep apnea. The main feature that distinguishes our device from these commercial products is that our device uses one thermistor while these other devices have two or more thermistors. Even with this distinction we don’t believe there are many opportunities for patenting with our ...

Comparison of Nasal Pressure Transducer and Thermistor for ...

light (sensor attached to the vest to record on/off). The thermistor and transducer signals were collected simultaneously by taping a nasal/oral thermocouple (Protec, Woodinville, Wash) on the su perior surface of a nasal cannula (Salter Labs, Arvin, Calif). The filter settings for the thermistor and the transducer channels were 5 Hz for the highfrequency filter and Hz for the lowfre ...

Accuracy of thermistors and thermocouples as flow ...

sleep studies requires a laboratory study under controlled conditions. Indeed, contrary to what happens when testing linear transducers, the analysis of a slowresponse nonlin ear system such as a thermistor/thermocouple [6] requires subjecting it to a variety of input airflows covering the ranges of amplitudes, frequencies and waveforms found in the particular application. Such a systematic ...

Sensors in Sleep Apnea and Sleep Study Equipment

Sensors or Sleep Apnea and Sleep Study Euipment PAGE 6 Sensors, like electronics in general, continue to evolve with smaller footprints, better accuracy, fully digital outputs and lower power. Low power operation allows them to be used in a wider range of applications including battery powered systems. Smaller footprints allow the sensors to be located closer to the breathing mask and allows ...

Comparison of nasal pressure transducer and thermistor for ...

Study objectives: The results of small studies have suggested that a nasalcannula pressure transducer has a higher sensitivity than a thermistor in detecting hypopneas and diagnosing sleepdisordered breathing in both adults and children. We compared a thermistor alone, and in conjunction with a pressure transducer, for detection of sleepdisordered breathing in children during inhome ...
