Purpoes: The study was done to investigate the effects of an exercise program on body composition, cardiopulmonary function and physical fitness in obese children. Methods: Thirty nine children in grades 4, 5, and 6 in elementary school were employed: experimental group(20) and control group(19). The subjects in the experimental group participated in an exercise program for 8weeks, thirty five minutes per session, four times per week. This data was analyzed by ANCOVA and paired t-test. Result: The Height(F=2.615, p=0.027) of the experimental group was significantly different from the control group. Also, in the experimental group, there were significant differences of height(t=4 79, p=0.000), cardiac rate(t=-6.461, p=0.000), body mass index(t=-2.13 p=0.046), muscle strength(t=3.48, p=0.003), and muscle endurance(t=3.20, p=0.005). Otherwise, in the control group, there were significant differences of weight(t=2.27, p=0.036), waist-hip ratio(t=3.16, p=0.005), and muscle endurance(t=-2.38, p=0.030). Conclusion: Jumping rope improved the body composition, cardiopulmonary function, and physical fitness for obese children.

To protect the patient's internal organs when a patient with cardiovascular disease occurs, it is important to reduce the elapsed time by providing emergency medical services. Decisions for conducting cardiopulmonary resuscitation are mainly made using the carotid palpation method, which directs the pulse of the carotid artery, which can diagnose the patient's condition according to one's own subject and cause cerebral blood flow to be blocked by excessive pressure in the carotid due to the weaken cardiopulmonary function. In this study, we developed a multimodal patch-type probe based on multi-channel ultrasound Doppler pairs and oxygen saturation measurement modules which can monitor cardiopulmonary functions. From the in-vivo experiments, the developed probe can be utilized as a novel tool that can increase the survival rate of cardiovascular disease patients by objectively monitoring the cardiopulmonary function of the patient quantitatively and promptly in an emergency situation.

PURPOSE: Recently, the proportion of respiratory diseases has been increasing worldwide, and deaths from respiratory diseases in Korea are increasing. Maintaining a healthy respiratory function is a crucial factor in preventing respiratory diseases. There are various ways to improve respiratory function, such as respiratory muscle and aerobic exercises. In other countries, respiratory muscle exercise is performed using a respiratory resistance mask, but such research is insufficient in Korea. Therefore, this paper proposes a respiratory exercise program using a respiratory resistance mask. METHODS: This study was conducted by dividing healthy adults in their 20s into a treadmill exercise + respiratory resistance mask group and a treadmill exercise group into an experimental group and a control group. The changes in the subject's physical function before and after exercise were confirmed by cardiopulmonary exercise and pulmonary function tests. RESULTS: As a result of the study, the experimental and control groups increased their physical function significantly (p < .05). On the other hand, when the increase rate according to the group was confirmed, the increase rate of the experimental group was higher. CONCLUSION: Based on this study, it is necessary to develop a respiratory exercise program using respiratory exercise tools such as a respiratory resistance mask and provide it easily to various subjects.

The purpose of this study is to examine factors affecting knowledge about cardiopulmonary resuscitation of older persons. For the purpose of the study, 2022 Social Survey conducted by Statistics Korea was utilized and 8,862 older persons aged over 65 years old were analyzed. Results of the analyses showed that individual resources and social resources of older persons had significant effects on knowledge about cardiopulmonary resuscitation. Regarding individual resources, a higher level of education, a higher level of income, a higher level of subjective health status, and a higher level of cognitive function increased the level of knowledge about cardiopulmonary resuscitation of older persons. Regarding social resources, having a spouse and a higher level of satisfaction of relationship with children increased the level of knowledge about cardiopulmonary resuscitation of older persons. Based on results of this study, various interventions are needed to improve the level of knowledge about cardiopulmonary resuscitation among vulnerable older groups with regard to the coping knowledge with emergency situation.

This study examined the changes in the cardiopulmonary functions of stroke patients by adjusting the s heart rate during walking training. This study was conducted on 20 chronic stroke patients. The experimental group conducted walking training by varying the walking speed according to the change in heart rate on the treadmill. In contrast, the control group conducted walking training by the subjective speed of the subject. The walking training was conducted for 32 minutes, three times a week, for a total of six weeks. The changes after the intervention of the subjects were determined by measuring the VC, ERV, IRV, FVC, FEV1, and PEF. The study revealed interactions between the groups and timing in the VC, ERV, and IRV(p<.05). There were no interactions between the groups and timing in FEV1, FVC, and PEF. The main effects showed no significant differences between the groups (p>.05) but showed significant differences between periods (p<.05). These results suggest that the cardiopulmonary function was improved significantly when the training was conducted by changing the pace of the heart rate in the walking process, leading to significant changes in the cardiopulmonary function.

Cardiopulmonary depression of long-term constant rate infusion (CRI) administration of multiple analgesic drugs is important, especially in critically ill dogs. Therefore, this study was conducted to evaluate the effects of lidocaine, ketamine or combined lidocaine-ketamine combination CRI treatment on vital signs and left ventricular (LV) function in healthy dogs. Six adult Beagle dogs were administered either ketamine (initial loading dose of 0.5 mg/kg followed by $10{\mu}g/kg/min$ CRI), lidocaine (initial loading dose of 2 mg/kg followed by 0.025 mg/kg/min CRI), or combined lidocaine-ketamine intravenously. Arterial blood pressure (BP), heart rate (HR), respiratory rate (RR), body temperature (BT) and echocardiographic LV dimensions were measured before administration of medications, immediately after administration of drugs, and then every 10 min for 2 h. There were no significant changes in HR, RR, BT and BP after the administration of either lidocaine CRI, ketamine CRI, or combined lidocaine and ketamine CRI. There were also no significant changes in LV dimensions and stroke volume. The results revealed that treatment with either lidocaine, ketamine or combined lidocaine-ketamine may not cause cardiopulmonary suppression in healthy dogs.

Background : Patients with locally advanced non-small cell lung cancer are often treated with radiation alone or in combination with chemotherapy. Both modalities have a potentially damaging effect on pulmonary function. In order to examine changes in the cardiopulmonary exercise function of patients with locally advanced non-small cell lung cancer before and after conventional radiotherapy, we conducted a prospective study involving patients with such cancer, that had received radiation therapy. Method : Resting pulmonary function test, thoracic radiographic finding and cardiopulmonary exercise test(CPET) were assessed prior to and 4 weeks following radiation therapy in 11 male patients with locally advanced non-small cell lung cancer. Patient with endobronchial mass were excluded. Results : The forces vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$ and maximal voluntary ventilation (MVV) did not decreased between before and 4 weeks after radiation but the diffusing capacity (DLCO) had decreased by 11% 4 weeks after radiation, which was not statistically significant. No changes in maximal oxygen consumption ($VO_2$max), carbon dioxide production ($VCO_2$), exercise time and work load were attributed to radiation therapy. Follow up cardiopulmonary exercise testing revealed unchanged cardiovascular function, ventilatory function and gas exchange. No difference in cardiopulmonary exercise test performance was observed between pre- and post-radiation. Conclusion : Cardiopulmonary exercise function did not decrease within the short-term after the radiation of patients with locally advanced non-small cell lung cancer.

This study examines the effects of a rehabilitation program on quality of life (QOL), cardiopulmonary function and fatigue during radiotherapy for breast cancer patients. The program includes aerobic exercise, stretching and strengthening exercises. Sixty-five women participated in this study and they were asked to perform supervised exercises that last for 60 minutes five times a week for six weeks. The European organization for research and treatment of cancer-cancer (EORTC QLQ-C30) and the breast (EORTC QLQ-BR23), predicted maximal volume of oxygen consumption ($VO_{2max}$) and fatigue severity scale (FSS) were assessed before and after the rehabilitation program. The 60-minute program consisted of a 10-minute warm-up, 30-minute of aerobic exercises, and 15-minute of strengthening exercises, followed by a five-minute cool-down. Heart rates were monitored throughout the exercise class to ensure that patients were exercising at the target heart rate of 40~75% of the age-adjusted heart rate maximum. There were statistically significant differences in the changes of physical function and cancer related symptoms in the EORTC QLQ-C30 and EORTC QLQ-BR23 (p<.05). There was a statistically significant improvement in the predicted $VO_{2max}$ (p<.05), although there were no significant differences in the FSS (p>.05). The results of our study suggest that a supervised rehabilitation program may benefit the physical aspects and QOL of patients receiving radiotherapy for breast cancer.
