Objective: This study aims to assess the reliability and validity of the new hand-held spirometer as a potential substitute for traditional pulmonary function testing (PFT) devices. Design: Cross-sectional study. Methods: In this study, thirty healthy adults underwent spirometry using both the new hand-held spirometer and the MIR spirometer, which is a standard PFT device. Parameters including peak expiratory flow (PEF), forced expiratory volume in one second (FEV₁), and forced vital capacity (FVC) were measured and analyzed for validity and reliability. Inter-rater reliability and validity were evaluated through 95% limits of agreement (LOA) and intraclass correlation coefficients (ICC). Statistical analyses, including the Bland-Altman plots and the ICC, were utilized to assess agreement between the two devices. Results: The new hand-held spirometer exhibited a good agreement with intra-class coefficient (ICC [2,1]) ranging 0.762 to 0.956 and 95% LOA of -1.94 to 1.80 when compared with MIR. The test-retest reliability of the hand-held spirometer analyzed using - ICC [2,1] demonstrated a good level of consistency (ICC [2,1] =0.849-0.934). Conclusions: In conclusion, the study aimed to assess the potential of the new hand-held spirometer as a viable alternative to traditional PFT devices, with a specific focus on its reliability and validity in spirometric measurements. The new hand-held spirometer exhibited good test-retest reliability across all measured variables, suggesting its potential as a valid and reliable tool for simultaneous PFT measurements.

The nursing intervention for the prevention of the pulmonary complication and of the function lowering of pulmonary ventilation which emerge with high generation frequency during the nursing of operation patient is necessary for performing the qualitative nursing for operation patient. So, this researcher tried this study so as to obtain the data which can be utilized for the trial of nursing intervention, by grasping the effect that the deep breathing with Incentive Spirometer has on the function of pulmonary ventilation, analysing the factor to have influence on the function of pulmonary ventilation, and applying the effective method of deep breathing to the clinic. By making 42 patients who underwent the operation of upper abdomen after admitting G Hospital in Seoul from Mar. 7, 1991 to Apr.30, 1991 as the object, they were classified into the experiment group that the deep breathing was made with the use of Incentive Spiromenter and the comparison group that the deep breathing exercise was made without the use of Incentive Spirometer. And then, by measuring Tidal Volume and Forced Vital Capacity with Respirometer and $O_2$ Saturation with Pulse Oximeter at preoperation postoperation 24 hours, 72 hours, and 120 hours data were collected. The collected data were analyzed with of, average, standard deviation, x$^2$-test, t-test and ANOVA by SPSS. The result of this study is as follows : 1. As for the hypothesis that the function of pulmonary ventilation at postoperation 24 hours, 72 hours and 120 hours will be better in the experiment group that the deep breathing was made with the use of Incentive Spirometer, in comparison with the comparison group that deep breathing was made without the use of Incentive Spirometer, experiment group and comparison group didn't show the significant difference in Tidal Volume, Foreced Vital Capacity and $O_2$ Saturation at postoperation 24 hours and 72 hours. But experiment group and comparison group showed the significant difference in Tidal Volume at postoperation 120 hours (p＜0.01). So, this hypothesis was supported partially. 2. The variables that there were the significant differences about the function of pulmonary ventilation in experiment group at postoperation 24 hours stastically were smoking existence (p＜0.05), and the variables that there were not significant differences about the function of pulmonary ventilation were distinction of sex, age, anesthetic duration, smoking extent, body weight, surface area of body, existence of narcotic use, regular exercise existence, and past experience existence of respiratory disease. As above result, it appeared that the method of deep breathing with the use of the Incentive Spirometer is more effective for the function recovery of pulmonary ventilation, in comparison with the deep breathing without use of Incentive Spirometer and that smoking existence was the factor to have influence on the function of pulmonary ventilation. In the aspect of clinic, the trial of nursing intervention of deep breathing with use of Incentive Spirometer is expected. And, in the aspect of study, the study through various operative site patients about the effect of Incentive Spirometer use at the clinic will have to be confirmed.

We have developed the spirometer system; many patients having weak respiration have difficulties in using conventional spirometers in hospitals, because their weak breath can be affected by the errors of inertia and instrumental pressure. We have developed a new ultrasound spirometer using an ARM 920T processor. To detect weak respiratory signals, we add a comparator circuit, which can afford more information of respiration characteristics such as respiration volume, directions, and velocities. We have also developed Gill for graphical display of respiration characteristics. Through the pilot test, it has been verified that the developed spirometer is operating reliably.

Purpose: This study was to examine the effects of deep breathing exercises with Incentive Spirometer on the pulmonary ventilatory function of pnemothorax patients undergoing a thoracotomy. Mothod: This experiment used anonequivalent control group non-synchronized design which compared pre-experimental measures with post-experimental ones. The subjects of this study were 34 inpatients who were scheduled for a thoracotomy and classified into the experimental group (17 patients) or control group (17 patients) by using an Incentive Spirometer or not. The collected data was analyzed by a SPSS Win I PC (percentage, mean, standard deviation, chi-square test, t-test, repeated measured two-way ANOVA). Result: The Pulmonary Ventilatory Function of the experimental and control group were significantly increased on the first day, third day, and fifth day after the thoracotomy, but the group interaction period was not significant. Conclusion: This study showed that the deep breathing exercises with an Incentive Spirometer and deep breathing exercise without an Incentive Spirometer were both effective for recovering the pulmonary ventilatory function after a thoracotomy.

폐 기능 검사는 임상에서 환자의 진단 및 치료 판단에 널리 이용되고 있을 뿐 아니라 폐의 연구, 특히 폐의 생리학 및 폐질환의 역학 연구에 일찍부터 사용되어 왔다. 여러 가지 폐 기능 검사 중 가장 쉽고 경제적으로 시행할 수 있는 기본적인 검사법으로 폐활량 검사법(Spirometer)이 있다. 폐활량 검사기는 호흡 기체의 용적 유량의 순간적인 변화량을 측정하는 의학 기기이다. 과거에는 기계식 폐활량기가 주로 사용되었으며, 현재까지도 많이 사용되는 방법은 유체 흐름의 "양" 변화를 유체의 압력 변화로 전환시키는 차압식 방식이다. 그러나 이러한 형태는 압력 손실과 유지 보수가 힘들고, 특성 검사 주기가 짧은 단점을 가지고 있다. 본 논문에서 구현하고자 하는 것은 관성의 오차 및 압력의 오차에 영향을 거의 받지 않는, 그리고 반영구적으로 사용이 가능한 초음파 센싱 방식을 이용한 임베디드 환경의 호흡 량 측정기의 개발을 최종 목표로 하여, 호흡 기체 특성에 적합한 센서, 신호 측정 구현 회로를 포함한 유량 측정 단말부 개발과 측정신호를 이용한 호흡 측정 알고리즘과 진단 알고리즘 구현에 중점을 두었다.

Background: This study aims to examine the useful- ness of the portable spirometer "The Spirokit" as a clinical diagnostic device through technology introduction, precision test, and correction. Design: Technical note Methods: "The Spirokit" was developed using a propeller-type flow rate and flow rate measurement method using infrared and light detection sensors. The level of agreement between the Pulmonary Waveform Generator and the measured values was checked to determine the precision of "The Spirokit", and the correction equation was included using the Pulmonary Waveform Generator software to correct the error range. The analysis was requested using the ATS 24/26 waveform recognized by the Ministry of Food and Drug Safety and the American Thoracic Society for the values of Forced Voluntary Capacity (FVC), Forced Expiratory Volume in 1second (FEV1), and Peak Expiratory Flow (PEF), which are used as major indicators for pulmonary function tests. All tests were repeated five times to derive an average value, and FVC and FEV1 presented accuracy and PEF presented accuracy as the result values. Results: FVC and FEV1 of 'The Spirokit' developed in this study showed accuracy within ± 3% of the error level in the ATS 24 waveform. The PEF value of 'The Spirokit' showed accuracy within the error level ± 12% of the ATS 26 waveform. Conclusion: Through the results of this study, the precision of 'The Spirokit' as a clinical diagnosis device was identified, and it was confirmed that it can be used as a portable pulmonary function test that can replace a spirometer.
