PURPOSE: To solve the problems of chronic obstructive pulmonary disease (COPD) patients complaining of muscle fatigue and having limited motor abilities, this study provided the clinical basic data for pulmonary rehabilitation by examining the effects of High Low-Frequency Neuromuscular Electrical Stimulation (NMES) on the respiratory muscle strength, quadriceps muscle activity, and life quality. METHODS: Samples were collected from 20 COPD patients and placed randomly in a low-frequency group (n=10) and high-frequency group (n=10). For a pretest, the respiratory muscle strength (MIP, MEP), quadriceps muscle activity (LF, VM, VL), and life quality (SGRQ) were measured. After applying NMES to each group for 30 minutes at a time, five times a week, for four weeks, a posttest was conducted in the same way as the pretest. RESULTS: Both groups showed significant differences in the respiratory muscle strength, quadriceps muscle activity, and quality of life within the groups and there were significant differences in the quadriceps muscle activity between the groups. CONCLUSION: The four-weeks NMES positively influenced the respiratory muscle strength and life quality by enhancing the function of the quadriceps and exercise tolerance. In particular, high-frequency(75 Hz) NMES was more effective than low-frequency (15 Hz) NMES. This result can be an alternative means to improve the physical functions of COPD patients clinically in the future.

Background: The purpose of this study was to determine whether components of the ProVent model can predict the high medical costs in Korean patients requiring at least 21 days of mechanical ventilation (prolonged mechanical ventilation [PMV]). Methods: Retrospective data from 302 patients (61.6% male; median age, 63.0 years) who had received PMV in the past 5 years were analyzed. To determine the relationship between medical cost per patient and components of the ProVent model, we collected the following data on day 21 of mechanical ventilation (MV): age, blood platelet count, requirement for hemodialysis, and requirement for vasopressors. Results: The mortality rate in the intensive care unit (ICU) was 31.5%. The average medical costs per patient during ICU and total hospital (ICU and general ward) stay were 35,105 and 41,110 US dollars (USD), respectively. The following components of the ProVent model were associated with higher medical costs during ICU stay: age <50 years (average 42,731 USD vs. 33,710 USD, p=0.001), thrombocytopenia on day 21 of MV (36,237 USD vs. 34,783 USD, p=0.009), and requirement for hemodialysis on day 21 of MV (57,864 USD vs. 33,509 USD, p<0.001). As the number of these three components increased, a positive correlation was found betweeen medical costs and ICU stay based on the Pearson's correlation coefficient (${\gamma}$) (${\gamma}=0.367$, p<0.001). Conclusion: The ProVent model can be used to predict high medical costs in PMV patients during ICU stay. The highest medical costs were for patients who required hemodialysis on day 21 of MV.

Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

Obesity hypoventilation syndrome (OHS) is defined as the triad of obesity (body mass index, [BMI] ≥ 30 kg/m²), daytime hypercapnia (PaCO2 ≥ 45 mm Hg), and sleep breathing disorder, after excluding other causes for hypoventilation. As the obese population increases worldwide, the prevalence of OHS is also on the rise. Patients with OHS have poor quality of life, high risk of frequent hospitalization and increased cardiopulmonary mortality. However, most patients with OHS remain undiagnosed and untreated. The diagnosis typically occurs during the 5th and 6th decades of life and frequently first diagnosed in emergency rooms as a result of acute-on-chronic hypercapnic respiratory failure. Due to the high mortality rate in patients with OHS who do not receive treatment or have developed respiratory failure, early recognition and effective treatment is essential for improving outcomes. Positive airway pressure (PAP) therapy including continuous PAP (CPAP) or noninvasive ventilation (NIV) is the primary management option for OHS. Changes in lifestyle, rehabilitation program, weight loss and bariatric surgery should be also considered.

The purpose of this study is to examine the effects of feedback breathing exercise on respiratory muscle activity. Thirty stroke patients were randomly and equally assigned to an experimental group and a control group. The experimental group received rehabilitation exercise treatment for 30 minutes and feedback respiratory exercise for 30 minutes and the control group received rehabilitation exercise treatment for 30 minutes and conducted motomed exercise for 30 minutes. All of them conducted exercises five times per week for four weeks. Respiratory muscles including the upper trapezius(UT), longissimus dorsi(LD), rectus abdominis(RA), external abdominal oblique(EAO) and, internal abdominal oblique(IAO) were measured using MP 150WSW prior to and after the experiment. Regarding pulmonary functions prior to and after the experiment, the experimental group showed significant differences in all sections but the control group did not show significant differences in any sections. As for in-between group differences after the experiment, there were significant differences in the UT, LD, RA, and IAO but no significant differences in the EAO. In conclusion, respiratory muscle activity was more effective for the experimental group than the control group. It is considered that feedback respiratory exercise may induce improvement in respiratory muscles in stroke patients through feedback breathing exercise.

만성 폐쇄성 폐질환은 비가역적, 점진적 기도 폐쇄가 특징인 주요 사망 원인중의 하나이다. 말기 폐쇄성 폐질환 환자는 다양한 신체적, 정서적, 사회적, 기능적 문제로 인해 호스피스 완화의료가 필요하다. 따라서, 완화의료의 목적은 증상 조절, 운동 능력 및 삶의 질 향상이며, 아울러 급성 악화 빈도를 줄이고 질병의 진행을 늦추는 효과를 기대할 수 있다. 다양한 진행 과정 때문에 말기 시점을 예측하기 어렵다. 호흡곤란 정도, 폐기능, 혈액학적 임상 지표를 이용하여 대상자를 선정하는 기준을 마련하고 적용시점을 논의해야 한다. 질환의 특성상 진단 후 초기에는 완치 목적의 치료가 중심이 되어 완화의료가 이를 보완하는 방식으로 적용되다가, 완치 목적의 치료를 위해 입 퇴원을 반복하거나 치료의 반응이 낮고 나쁜 예후가 예상될 때 완화의료 비중이 확대되는 것이 바람직하겠다. 폐쇄성 폐질환 환자에게 적극적으로 호흡재활을 적용하고, 환자의 의사결정을 존중하여 증상 악화 이전에 미리 대책을 마련하고 앞으로의 치료 목표를 논의하기 위한 완화의료 팀을 구성하고, 국내 현실에 맞는 진료 연계 체계를 마련하는 것이 필요하다. 제도가 잘 정착하기 위해서는 일차 의료 및 암환자 대상의 완화의료 전문 팀과의 협업이 중요하며, 우선 고려되어야 할 것이다.
