Maximal expiratory flow-volume [MEFV] curves were studied in 22 patients who underwent pneumonectomy with various pulmonary lesions, such as lung cancer, bronchiectasis and tuberculosis etc, at the preoperative stage and 3 week, 4 month and 12 month after pneumonectomy for the analysis of the reduction and progressive improvement of postoperative ventilatory function. And the factors affecting them like as age difference and the site of pneumonectomy were also analyzed. From these curves peak flow rate [PF R], maximal expiratory flows at 25% and 50% of expired forced vital capacity [V25, V50] and forced vital capacity [FVC] were obtained. In addition, partial pressure of oxygen and carbon dioxide in arterial blood were measured. The results were as follows; 1. The mixed type, especially obstructive type of ventilatory impairment was observed at 3 week after operation. For 1 year of postpneumonectomy FVC was increased by 12.3% of predicted compared to 2.6% of predicted V50. 2. The improvement of FVC during 1 year of postpneumonectomy showed decreasing tendency with the increase of age but the changes of V25 and V50 were unremarkable. 3. The differences of immediate postoperative reduction and progressive improvement of ventilatory capacity after right and left pneumonectomy were analyzed. The reduction of V50, V25 and FVC at 3 week of postoperation were greater in patients with right pneumonectomy [20.9%, 18.2% and 26.2% of predicted] than in patients with left pneumonectomy 16.5%, 18.2% and 18.1%]. But there was no significant difference of these values at 12 month after pneumonectomy. 4. The partial pressure of oxygen in arterial blood [$PaO_2$] was decreased by 13.6 mmHg at 3 week after pneumonectomy compared to the preoperative stage but returned to the normal range within 4 month after pneumonectomy. However, TEX>$PaCO_2$ was within the normal range during 1 year of postoperation.

연구배경 : 만성 폐쇄성 폐질환을 대변하는 폐기종에서 주요 기능적 장애는 호기의 장애이며, 최대 호기류량은 기도의 크기, 폐의 탄력반동압 그리고 기도의 함몰성에 의해 결정된다. 기도의 항몰성은 폐기종에서 기류를 제한하는 하나의 기전으로 작용하지만, 폐용적과 폐의 과팽창을 유지하는 기전으로 작용하여 가스교환을 증진시킨다는 주장도 있다. 따라서 폐기종에서 기관이 호흡에 미치는 생리학적 역할이 무엇인지를 알아보고자 본 연구를 수행하였다. 방 법 : 1997년 1월 1일부터 8월 31일까지 보라매병원 호흡기내과를 방문하여 단순 흉부방사선검사, 체간용적기록계(body plethysmography)를 포함하는 폐기능검사 및 HRCT를 통해 폐기종으로 진단된 20명을 대상으로 하였다. HRCT에서 대동맥궁의 정상부위에서 기관의 단면적을 호흡주기에 따라 측정하고 이를 체표면적으로 보정한 값과 동맥혈의 이산화탄소분압 및 산소분압, 기도저항, 폐유순도 등 폐기능지표와의 상관 관계를 분석하였다. 결 과 : 폐기종에서 기관의 단면적은 호기시 동맥혈의 이산화탄소분압(r=-0.61, p<0.05) 및 산소분압(r=0.6, p<0.05) 그리고 매분환기량(r=0.73, p<0.05)과 유의한 상관관계가 있었지만, 흡기시에는 상관관계가 없었다(이산화탄소분압과는 r=-0.22, p>0.05, 산소분압과는 r=0.26, p>0.05, 매분환기량과는 r=0.44, p>0.05). 매분환기량은 상시호흡량(tidal volume)과는 r=0.45(p<0.05)로 유의한 상관관계가 있었지만, 호흡수와는 r=-0.31(p>0.05)로 상관관계가 없었다. 폐기종에서 기관의 단면적은 호흡주기와 상관없이 $FEV_1$ FVC, $FEV_1$/FEC, 최대 호기류량, 잔기용적, 폐확산능, 기도저항, 폐유순도 등의 다른 폐기능지표와는 상관관계가 없었다. 결 론 : 폐기종에서 호기시 기관의 단면적은 주로 가스 교환(gas exchange)의 지표들과 유의한 상관관계가 있었지만, 폐용적이나 폐의 과팽창을 시사하는 지표와는 상관관계가 없었다. 따라서 폐기종에서는 호기시 동일 압력점의 개념에 의해 발생하는 기도압박으로 기관의 단면적이 감소하고 이러한 현상이 기류를 제한하는 하나의 기전으로 작용하는 것이지 폐용적이나 폐의 과팽창을 유지시켜 가스교환을 증진시키는 것은 아니라고 생각된다.

The asthma is a clinical syndrome having three symptoms; dyspnea, wheezing and coughing, due to the narrowing of trachea in pulmonary system. Specially the asthma is common in children. The study was designed to identify the effect of Kinesio Taping Treatment as to asthmatic children. The Kinesio Taping Treatment was used on the Pectoralis major and Posterior diaphragm of twenty five asthmatic children(19 male, 6 female) for the period from September 1, 2001 to September 20, 2001. Peak expiratory flow rate(PEFR) for the condition of pulmonary function was measured using the Pocket Peak and wheeling and coughing symptom were measured using questionnaire. The results of this study are as follows: 1. There were statistically significant differences between before using the taping and after the kinesio taping increase of the PEFR(p<0.001). 2 There were statistically significant differences between before using the kinesio taping and after the kinesio taping improvement of the wheezing sign(p<0.001). 3. There were statistically significant differences between before using the kinesio taping and after the kinesio taping improvement of the coughing symptom(p<0.001).

Background: Patients with advanced asthma and chronic obstructive pulmonary disease (COPD) have postural deviations such as thoracic hyperkyphosis, forward shoulder posture (FSP) due to an increase in head and cervical protraction, reduced shoulder range of motion and a corresponding increase in scapula elevation and upward rotation. Unlike congenital vertebral kyphosis that are permanent and rigid deformities with bony and other structural deformations which cause respiratory impairment, these deformities in these patients may be more flexible. Since the thoracic hyperkyphosis has been implicated as having adverse health consequences it is necessary to evaluated the relationship between thoracic kyphosis and cardiopulmonary functions of patients with COPD and asthma. Methods: It was a cross-sectional analytical study. Eighty-four eligible patients with COPD and asthma were recruited from the Respiratory Unit, Department of Medicine, Lagos University Teaching Hospital (LUTH), and basic anthropometric parameters, pulmonary parameters, cardiovascular parameters, thoracic kyphosis (Cobb) angle and presence of respiratory symptoms of participants were assessed. Data was analyzed using SPSS version 20. Results: There was no significant correlation between the thoracic kyphosis and selected pulmonary parameters (Forced Expiratory Volume in one second (FEV1, p=0.36), Forced Vital Capacity (FVC, p=0.95), Peak Expiratory Flow Rate (PEFR, p=0.16), Thoracic expansion (TE, p=0.27)/cardiovascular parameters (Systolic Blood Pressure (SBP, p=0.108), Diastolic Blood Pressure (DBP, p=0.17) and Pulse Rate (PR, p=0.93) as well as the respiratory symptoms (SGRQ scores, p=0.11) in all subjects. Conclusion: There was no relationship between thoracic kyphosis and selected pulmonary/cardiovascular parameters as well as respiratory symptoms in patients with COPD and asthma.

Objective: The purpose of this study was to investigate the effect of cervical range of motion training on the change in respiratory function growth rate at the group and individual level in stroke patients and stroke patients with tracheostomy tube. Design: A Multilevel Growth Model Methods: 8 general stroke patients and 6 stroke patients who had a tracheostomy tube inserted were subjected to cervical range of motion training 3 times a week for 4 weeks. Force vital capacity (FVC), Forced expiratory volume in the first second (FEV1), Forced expiration ratio (FEV1/FVC) and Manual assist peak cough flow (MPCF) were measured. Data were analyzed using descriptive statistics and multilevel analysis with HLM 8.0. Results: A significant difference was found in the respiratory function analysis growth rate of the entire group (p<0.05), and two groups were added to the research model. The linear growth rate of respiratory function in patients with general stroke increased with the exception of FEV1/FVC (p<0.05). Stroke patients with tracheostomy tube showed a decreasing pattern except for FVC. In particular, MPCF showed a significantly decreased result (p<0.05). Conclusions: This study found that the maintenance of improved respiratory function in stroke patients with tracheostomy tube decreased over time. However, cervical range of motion training is still a useful method for respiratory function in general stroke patients and stroke patients with tracheostomy tube.

연구배경 : 휴대용 PFMs에 의한 PEFR측정은 쉽고 간편하여 천식의 진단과 추적관찰에 널리 이용되고 있는데, 이들에 의해 측정된 PEFR성적이 얼마나 믿을만 할 것인지는 의문이다. 따라서 저자는 전산화폐기능검사기계인 pneumotachygraph를 기준으로 MPFM에 의한 PEFR측정의 정확도, 일치성, 정밀성을 검토하고자 하였다. 방 법 : 22례의 정상인과 17례의 경증 및 중등도의 천식환자를 대상으로 휴대용 PFMs인 MPFM로 PEFR을 측정하였고 전산화폐기능검사기계인 pneumotachygraph로 폐환기기능검사를 시행하였으며, 이중 정상인만을 대상으로 서로 다른 3일 동안 연속적으로 같은 방법으로 폐기능검사를 시행하여 다음과 같은 결과를 얻었다. 결 과 : 정상인과 환자군 모두에서 MPFM로 측정한 PEFR은 pneumotachygraph 에 의해 측정한 PEFR, $FEV_1$과 유의한 순상관관계에 있었다(for PEFR, r = 0.92, p < 0.001 ; for $FEV_1$, r = 0.78 ; p < 0.001). 정상인과 환자군 모두에서 MPFM로 측정한 PEFR은 pneumotachygraph로 측정한 PEFR과 평균 16.5L/min의 차이(측정된 실제 PEFR의 2.90%)를 보였고 정상인만을 대상으로 했을 때는 10.6L/min의 차이(측정된 실제 PEFR의 1.75%)를 보여 NAEP에서 추천한 정확도의 기준 10%이내로 높은 정확도를 나타냈다. 정상인과 환자군 모두에서 MPFM로 측정한 PEFR과 pneumotachygraph로 측정한 PEFR사이의 Bland-Altman방법에 의한 일치성은 회귀방정식을 이용해 교정했을 때 -71.5~+38.2L/min을 보였고 정상인만을 대상으로 했을 때는 -20.49~+9.49L/min을 보여, 정상인에서 연속 3 일간 얻은 개체내 일치성과 유사하였다. 정상인만을 대상으로 연속 3일간 MPFM로 측정한 PEFR과 pneumotachygrph에 의한 폐기능성적은 각각 횟수에 따라 유의한 차이가 없었고(p > 0.05), MPFM에 의한 PEFR의 CV는 $2.4{\pm}1.2%$로서 pneumotachygraph에 의한 $5.2{\pm}3.5%$보다 유의하게 작았다(p < 0.05). 결 론 : 이상의 성적으로 MPFM에 의해 측정한 PEFR은 전산화폐기능검사기계에 의한 폐기능성적과 다를 바 없는 좋은 성적을 측정할 수 있어서 기관지 천식환자의 폐기능상태의 변화양상을 추적관찰하는데 유용한 것으로 사료되었다.

Objectives : Dyspnea is one of the most common symptoms that we meet, but so far there has been no research about the effects of acupuncture therapy on it. This study was performed in order to evaluate the effect of acupuncture therapy on dyspnea by means of using objective indexes. Methods : The effect of acupuncture therapy was assessed by analyzing the pulmonary function test (PFT) in 10 patients, who had suffered from dyspnea and had pain at the acupuncture point Tian-zong (SI11) when it was compressed by a finger, at our outpatient department. Each patient was treated with acupuncture therapy at both sides of Tian-zong. We compared the results of pre-treatment and post-treatment PFTs, including forced vital capacity (FVC), forced expiratory volume in one second (FEV 1.0), and peak expiratory flow rate (PEFR). Results : FVCs of pre-treatment and post-treatment PFTs were $2.23{\pm}0.34(L)$ and $2.40{\pm}0.36(L)$ respectively (P<0.01). FEV1.0s of pre-treatment and post-treatment PFTs were $1.54{\pm}0.37(L)$ and $1.65{\pm}0.41(L)$ respectively (p<0.05). PEFRs of pre-treatment and post-treatment PFTs were $3.41{\pm}1.26(L)$ and $3.93{\pm}1.42(L)$ respectively (p<0.05). Conclusions From the above data, we conclude that FVC, FEV1.0, and PEFR in dyspneic patients have been improved after acupuncture therapy of Tian-zong, so acupuncture therapy of Tian-zong may relieve the dyspnea symptom.

Objectives: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients. Materials and Methods: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern. Results: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17-63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns. Conclusion: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

To evaluate the acute effects of fine particles on pulmonary function, a longitudinal study was conducted. This study was carried out for the schoolchildren (3rd and 6th grades) living in Beijing, China. Children were asked to record their daily levels of peak expiratory flow rate using portable peak flow meter (mini-Wright) for 40 days. The relationship between daily PEFR and fine particle levels was analyzed using a mixed linear regression models including gender, height, the presence of respiratory symptoms, and daily average temperature and relative humidity as extraneous variables. The total number of students participating in this longitudinal study was 87. Daily measured PEFR was in the range of $253{\sim}501L/min$. On the daily basis, a PEFR measured in the morning was shown to be lower than that measured in the evening (or afternoon). The daily mean concentrations of $PM_{10}$ and $PM_{2.5}$ over the study period were $180.2\;{\mu}g/m^3$ and $103.2\;{\mu}g/m^3$, respectively. The IQR (inter-quartile range) of $PM_{10}$ and $PM_{2.5}$ were $91.8\;{\mu}g/m^3$ and $58.0\;{\mu}g/m^3$. Daily mean PEFR was regressed with the 24-hour average $PM_{10}$ (or $PM_{2.5}$) levels, weather information such as air temperature and relative humidity, and individual characteristics including gender, height, and respiratory symptoms. The analysis showed that the increase of fine particle concentrations was negatively associated with the variability in PEFR. The IQR increments of $PM_{10}$ or $PM_{2.5}$ (at 1-day time lag) were also shown to be related with 1.54L/min (95% Confidence intervals -2.14, -0.94) and 1.56L/min (95% CI -2.16, -0.95) decline in PEFR.
