  • To study the recovery pattern of pulmonary function after decortication, the author performed serial pulmonary function tests using spirometry before and at lst., 3rd., 4th. week, lst., 3rd., 6th. month and 1st. year in 36 patients who underwent decortication from January 1989 to September 1991 at the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, Pusan, Korea. Patients were divided into 3 groups by the degree of compression of lung parenchyme. Group I was classified below 20%, Group II between 21 to 40%, Group III above 41%. Their serial changes of pulmonary function test were compared. The obtained results were as follows; 1. Maximal voluntary ventilation was recovered in 1st post perative week and even greater improvement was noted in group III in which ratio to 44 % of the preoperative value. 2. Vital capacity reached nearly to preoperative values in 3rd postoperative week and had increased much further to 26 % above the preoperative figure in group II. 3. Forced expiratory volume in 1 second returned rather slowly in 3rd-4th postoperative week and the mean VC was improved more higher in group II than the other groups following decorti cation. 4. There was an greatest improvement over all tests[MW, VC, FEV1] in 2nd decade which ratios to preoperative value were 34, 25 and 22 % respectively.

  • The purpose of this study was to determine whether respiratory physical therapy might increase the pulmonary function of the patients with stroke or not. Twenty patients with stroke were randomly assigned to experimental and control group. During four weeks, both groups participated in the conventional physical therapy and only the experimental group added in a program of respiratory physical therapy. Respiratory physical therapy consisted of chest mobilization, resistive ventilatory muscle training used the method of PNF technique and relaxed diaphragm breathing. Baseline and post-test measurements were made of vital capacity. inspiratory capacity, expiratory reserve volume, farced vital capacity, forced expiratory volume at one second, $FE1/FVC(\%)$ and maximal voluntary ventilation. Ater four weeks, the experimental group showed the significant improvement in VC(p<.05). FVC(p<.05), FFV1(p<.05) md MVV(p<.05). However, the controll group showed no significant differnece. As compared th the relationship of dependent variables between the experimental group and control group. experimental group showed the significant difference in VC(p<.01), FEV1(p<.05) and MVV(p<.05). These findings suggest that respiratory physical therapy can be used to improve pulmonary function in stroke patients. Also, respiratory physical therapy should be performed for at least four weeks and be followed by the continuous respiratory exercise programs.

  • Twenty-two patients were selected for evaluation of pre-and postoperative pulmonary function. These patients were performed open cardiac surgery with the extracorporeal circulation from March 1979 to July 1980 at the Department of Thoracic and Cardiovascular Surgery, Kyungbook National University Hospital. Patients were classified with ventricular septal defect 5 cases, atrial septal defect 5 cases, tetralogy of Fallot 5 cases, mitral stenosis 4 cases, rupture of aneurysm of sinus Valsalva 1 case, left atrial myxoma I case, and aortic insufficiency 1 case. The pulmonary function tests were performed and listed: [1] respiratory rate, tidal volume [TV], and minute volume[MV], [2] forced vital capacity [FVC] and forced expiratory volume[FEV 0.5 & FEV 1.0], [3] forced expiratory flow [FEF 200-1200 ml & FEF 25-75%]. [4] Maximal voluntary ventilation [MVV], [5] residual volume [RV] and functional residual capacity[FRC], measured by a helium dilution technique. Respiratory rate increased during the early postoperative days and tidal volume decreased significantly. These values returned to the preoperative levels after postoperative 5-6 days. Minute volume decreased slightly, but essentially unchanged. Preoperative mean values of the forced vital capacity, functional residual capacity and total lung capacity decreased [63.2%, 87.2% & 77.3% predicted, respectively], and early postoperatively these values decreased further [19.6%, 76.0% & 38.0% predicted], but later progressively increased to the preoperative levels. In residual volume, there was no decline in the preoperative mean values [100.9% predicted] and postoperatively the value rather increased [106.3-161.7% predicted]. Forced expiratory volume [FEV 0.5 & FEV 1.0] and forced expiratory flow [FEF 200-1200 ml & FEF 25-75%] also revealed significant declines in the early postoperative period. There was no significant difference in values of the spirometric pulmonary function tests, such as FEF 1.O and FEF 25-75% between successful weaning group [17 cases] extubated within 24 hrs post-operatively and unsuccessful weaning group [5 cases] extubated beyond 24 hrs. Static compliance and airway resistance measured for the two cases during assisted ventilation, however, any information was not obtained. Long term follow-up pulmonary function studies were carried out for 8 cases in 9 months post-operatively. All of the results returned to the pre-operative or to normal predicted levels except FVC, FEV 1.0, and FEF 25-75% those showed minimal declines compared to the pre-operative figures.

  • Background: Farinelli breathing (FB) exercise is a typical breathing exercise used by singers. This study aimed to compare effects of FB exercise and diaphragmatic breathing (DB) exercise on respiratory function and symptoms in patients with chronic obstructive pulmonary disease (COPD). Methods: Sixteen patients aged 51-80 years with mild or moderate COPD were recruited for this study. They were divided into two groups: DB group (n=8) and FB group (n=8). Both groups received complete breathing exercise training five times per week for 8 weeks. Their respiratory functions, COPD symptoms, cytokine levels, and oxidative stress variables were analyzed during pre- and post-tests. Dependent variables were compared between pre- and post-tests using paired t-tests. An independent t-test was used to compare variables between the groups. Differences were considered significant at p<0.05. Results: The maximal expiratory pressure (MEP), maximum oxygen consumption (VO2max), and COPD Assessment Test (CAT) scores changed significantly in the DB group after the 8-week intervention compared to those at pre-test, whereas force vital capacity, forced expiratory volume in the first second, maximum voluntary ventilation, maximal inspiratory pressure (MIP), MEP, VO2max, CAT score, tumor necrosis factor-α, and malondialdehyde level changed significantly in the FB group at post-test compared to those at pre-test. Moreover, both MIP and MEP in the FB group were significantly higher than those in the DB group. Conclusion: FB exercise improved respiratory functions and COPD symptoms of patients with COPD. It might be an alternative breathing exercise in pulmonary rehabilitation programs for patients with COPD.

  • The maximum voluntary ventilation (MVV) is one of the most widely used pulmonary function test, but its measuring method was very difficult and unreliable. However, it is need to get more easy and simple measuring method of MVV. Therefore, this study was attempted to get more easy and simple measuring method of MVV by means of the forced expiratory volume $(FEV_{T})$. The young and healthy 1,000 Korean students(592 male and 408 female) were cheesed for this purpose and whose ages were from 8 to 20 years. A spirometer (9L, Collins Co.) was used for the MVV and FEV, and they were measured 3 times at standing position, and the highest value was used. In the measurements, the subjects for MVV were asked for the breath as fast and deeply as possible for 12 seconds, and for FEV were asked for the rapid and forceful exhalation after a maximal inhalation (forced expiratory curve). In the FEV measurements toward the end of the expiration, the subjects were exhaused to continue the effort until no further gas was expired. During these measurements, the investigator stood by the subject to give a constant encouragement. FEV were calculated in the volume exhaled during the one-half $(FEV_{0{\cdot}5,}\;ml)$, the first second $(FEV_{1{\cdot}0,}\;ml)$ and the percentage of the total vital capacity exhaled during the one-half second $(FEV_{0{\cdot}5,}\;%)$. The results are summarized as follows: 1) The values of MVV were increased linearly with ages until 20 in both sexes. The values of male at the age of 20 was $168.2{\pm}2.5L/min$, and female at the age of 17 was $112.3{\pm}3.0L/min$, respectively. 2) The values of FEV (ml) were increased linearly with ages until 20 in both sexes. The values of $FEV_{0{\cdot}5}$ were $2,797{\pm}65.7ml$ in the male of 20 years and were $2,088{\pm}54.6ml$ in the female of 17 years, and of $FEV_{1{\cdot}0$ were $4,119{\pm}68.2ml$ in the male of 20 years and were $2,897{\pm}65.9ml$ in the female of 17 years, respectively. 3) The correlation coefficients between MVV and $FEV_{0{\cdot}5}\;or\;FEV_{1{\cdot}0$ (ml) were 0.82 or 0.85 in the male, and 0.77 or 0.79 in the female, respectively. 4) The prediction formulae for MVV to be derived from above results were: For male: MVV (L/min) =7.19+$0.05{\times}FEV_{0\cdot5}(ml)$, MVV (L/min)=11.25+$0.04{\times}FEV_{1\cdot0}(ml)$ For female: MVV (L/min)=16.03+$0.05{\times}FEV_{0\cdot5}(ml)$, MVV (L/min)=9.47+$0.03{\times}FEV_{1\cdot0}(ml)$.

  • Purpose : This study attempts to examine the effect of the balance exercise on the unstable surfaces for the vital capacity in healthy adults. Methods : A total of 13 subjects was randomly divided into a breathing exercise training group (n=7) and a breathing and balance exercise training group (n=6). Changes in vital capacity and respiratory muscle activity were measured before and after the intervention. The intervention was performed three times a week for four weeks. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1) and maximal voluntary ventilation (MVV) were used as measurement tools for the vital capacity test. Electromyography (EMG) was also used to examine respiratory muscle activity. Result : The breathing exercise training group showed significant improvement in terms of FVC, FEV1 and external oblique (EO), and transverse abdominis/internal oblique (TrA/IO) of MVV. The breathing and balance exercise training group showed significant improvement in terms of FVC, MVV and EO, TrA/IO of FVC and rectus abdominis (RA), EO, and TrA/IO of MVV. However, in comparing changes in vital capacity and respiratory muscle activity before and after the training, the breathing exercise training group and the breathing and balance exercise training group showed a significant difference in terms of MVV. Conclusion : This study is as a preliminary study to find out the relation between a balance exercise and a vital capacity, it is considered to require a further study with several revisions of subjects, duration and time for an intervention.

  • PURPOSE: The purpose of this study was to investigate which treadmill walking training mode is more effective strategy for improving pulmonary function of persons with chronic stroke. METHODS: Twenty-one chronic stroke patients were allocated and randomly to an experimental group (treadmill training with randomized speed control, n=11) and a control group (treadmill training without speed change, n=10). All participants received 30 minutes of neurodevelopmental treatment. In addition, the two groups performed treadmill training for 20 minutes each time with or without speed change. Speed change was applied 40%, 50%, 60%, 70% of Heart Rate Reserve. All the exercise programs lasted six weeks, with five times per week. Pulmonary function was assessed before and after exercise program by using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV). RESULTS: In the both groups, FEV1 was significantly increased after training (p<.05). Compared to the control group, the experimental group showed 11.9% larger amount of change (p<.05). In the experimental group, FVC and MVV were significantly increased after training (9.9%, 7.6%, respectively) (p<.05). But in the control group, there was no significant difference in the FVC and MVV after training. CONCLUSION: Treadmill training with randomized speed control will be a better positive rehabilitation program than treadmill training without speed change to improve pulmonary function in persons with chronic stroke.
