하드웨어 부분에서 시제품으로 초음파 호흡측정기 센서부， PC Interfacing부， rs232c 케이블， 부속품을 개발하였고 신호처리 소프트웨어 알고리즘을 개발하였다. 또한 개발된 호흡측정기의 동작과 추출 알고리즘 성능을 검증하기 위해 3가지 검사항목에 걸쳐서 시험을 수행하여 좋은 결과를 얻었다. 파라미터 값은 초음파 호흡측정 상수와 계수 보정을 통해 좀 더 정확해 질 수 있을 것이다.

Respiration detection device has been adopted as the study subject for several years, however, desired result necessary for the commercialization has not fully been induced.
1st generation respiration detection device, commercialized at present, measures the flow and amount of respiration with the turning ratio, using the turbine in sensing method, however, it has shortcomings in that measurement error is caused by the turbine inertia at the start and end point of measurement. Measurement to use pressure sensor can be said as the 2nd generation device. This device measures the amount and flow of respiration through measuring the interference rates by the resistor in breathing.
However, this method is inconvenient in that it should be calibrated depending on the change in external environment.
In light of this, it is necessary to study on the respiration measurement system using the ultrasound sensor, which can be used semi-permanently and is not subject to the error in inertia and pressure, as the 3rd generation device.
Accordingly, this study is to mass-produce the supplemented system by researching and developing the basic ultrasound sensor, hardware design for signal process, production of prototype and processing software algorithm, as well as experimenting and evaluating at the clinical situation.
As a result of this study, ultrasound respiration detection censor, PC Interfacing, rs232c cable, parts in hardware part, as well as signal process software algorithm were developed as the commercial product. In addition, good results were obtained in testing by 3 test items, to verify the performance of extraction algorithm and action of developed breath measurement. Parameter value can be more exactly obtained through correcting the constant and variable of ultrasound respiration detection.
This thesis can be applied to probe part of measurement device related to respiration, including respiration part of stress electrocardiograph, respiration part of advanced patient monitoring system, anesthesia device and respiratory device.
