Purpose: This study was to analyze the sustainable effects of cardiopulmonary resuscitation (CPR) reeducation on nurses' knowledge and skills. Methods: A repeated experimental design was used for a single sample group of 47 nurses working for a general hospital. The nurses were tested on their skill of CPR 3 times at an interval of 4 m1onths. In order to test nurses' knowledge and skills, the researcher used a CPR assessment program linked to an adult practice doll (Anne). Results: 1) The amount of decrease of nurses' knowledge about CPR between points of time was wide between first and second points of time but small between the second and third time owing to the effects of reeducation between the two points of time. 2) Nurses' skills between the first and second time dropped but they improved between the second and third time owing to the effects of reeducation. Conclusion: As confirmed by the above findings, reeducation of CPR clearly affects nurses' knowledge and skills. Given the fact that the same period of time (4 months) elapsed between the 3 tests, it could be argued that the reeducation at the second test served to maintain nurses' knowledge and enhance their skills.

Background: Various functional factors should be incorporated during assessment and intervention for patient rehabilitation. Stable respiratory function is one of required factors for functional restoration. To maximize respiratory physical therapy intervention outcome, it is required to understand clinical features of respiratory diseases and physical therapy approaches. Methods: Previous studies were systematically reviewed through computerized search. Methodological qualities of selected studies were evaluated and the levels of recommendations were determined. Results: Assessment for respiratory pattern and thoracic mobility is of importance to improve cardiopulmonary fitness during physical reconditioning. Application of optimal therapeutic protocol can increase thoracic mobility and respiratory function. Interdisciplinary communication is critical during rehabilitation for respiratory patients. Health care provider should have professional knowledge and experience for cardiopulmonary fitness and obligation to endeavor for patients' respiratory rehabilitation. It is necessary to standardize therapeutic intervention, and rehabilitative respiratory exercise should be applied to confirm the effects of intervention. Conclusion: Respiratory diseases that may reduce patients' quality of life and cardiopulmonary fitness should be resolved through physical therapy approaches. Through conducting research, effect of evidence-based and patients' function-oriented intervention can be determined.

A computational model representative of cardiovascular circulation was built using 12 standard lumped compartments. Especially, both the baroreceptor reflex and the cardiopulmonary reflex control model were implemented to explain the auto-regulation of cardiovascular system. Another important aspect of this model is to utilize the impulse-response curve of the nerve system in transferring the impulse error signals to autonomous nerve system. For the verification of this model, we have computed the normal hemodynamic conditions and compared those with the clinical data. Then. hemodynamic shock of 20% hemorrhage to cardiovascular system was simulated to test the effects of the control system model. The results of these two simulations were well matched with the experimental ones. The steady state LBNP simulation was also performed. The transient changes of hemodynamic variables due to ramp increase of bias pressure of LBNP showed good agreement with the physiological experiments. Numerical solution using only the baroreflex model showed relatively a larger deviation from the experimental data. compared with the one using the control model haying both the baroreflex and the cardiopulmonary reflex systems, which shows an important role of the cardiopulmonary reflex system for the simulation of the hemodynamic behavior of the cardiovascular system .

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.

Objectives : This study is a quasi-experiment with a pre-post design and a nonequivalent control group performed from May 1 to June 2, 2013 to verify the effects of a simulation based education program on nursing students' self-confidence, and clinical performance ability. Methods : The subjects of the study were a total of 60 students in their fourth year of a nursing program at a university located in G city and they were assigned to an experimental group of 30 students and a control group of 30 students by convenience sampling. Results : After being offered education, self-confidence, and clinical performance ability were significantly more improved than before in each group. In the comparison of the two groups, the self-confidence (t=3.00, p=.004) and clinical performance ability(t=3.14, p=.003) of the experiment group were significantly higher than those of the control group. Conclusions : The results indicated that instructional methods using a simulation-based emergency care program should be adopted maximize the effects of advanced cardiopulmonary life support education.

Cardiopulmonary bypass (CPB) for cardiac surgery induces the production and release of numerous chemotactic substances and cytokines, ensuing systemic inflammatory response that causes postoperative major organ dysfunctions. We performed a randomized, prospective study to investigate clinical effects of preoperative treated-methylprednisolone for preventing inflammation in pediatric cardiac surgery with CPB. Thirty pediatric patients scheduled for elective cardiac surgery were randomized to either control(n=15) or steroid group (n=15, 10 mg/kg of methylprednisolone). Arterial blood samples were taken before and after the operations for measuring total leukocyte (T-WBC) and differential counts, platelet counts, interleukin-6 (IL-6), myeloperoxidase (MPO), neuron specific enolase (NSE), troponin-I (TNI), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine levels. Postoperative parameters such as pulmonary index (PI, $PaO_2/FiO_2$), 24 hrs and total bleeding volumes, mechanical ventilating (MVP) and intensive care unit (ICU)-staying periods, and hospitalization were assessed. T-WBC, neutrophil fraction, IL-6, MPO, NSE, TNI, AST and creatinine levels, bleeding volumes, PI, and MVP at the postoperative periods were lower or shorter in steroid group than in control group (P<0.05). These findings indicated that preoperative administration of methylprednisolone attenuated CPB-induced inflammatory reactions, contributing to postoperative recovery of patients underwent cardiac surgery.

To compare cardiopulmonary effects and recovery between total intravenous anesthesia (TIVA) with propofol (PRO group, n=5) and volatile induction/maintenance anesthesia (VIMA) with isoflurane (ISO group, n=5), we investigated changes of heart rate, $SpO_2$, arterial pressure, rectal temperature and respiratory rate during 60 minute anesthesia and 40 minute recovery period in beagle dogs, and investigated recovery (extubation, head lift, sternal position and righting) after 60 minute anesthesia. Rectal temperature was significantly low in ISO group (p<0.05) from 10 to 100 minute. Heart rate was significantly low in ISO group (p<0.05) at 40, 50, 60 minute. Respiratory rate was significantly low in PRO group (p<0.05) at induction and 70 minute. $SpO_2$ tendency was similar. Systolic arterial pressure (SAP) was significantly low in ISO group (p<0.05) at induction and during anesthesia. Recovery was similar in two groups. We concluded that TIVA with propofol is useful in stabilizing rectal temperature and arterial pressure during anesthesia and provide fast and stable recovery.

Purpose: The purpose of this study was to determine the effects of knowledge and attitude on self efficacy of cardiopulmonary resuscitation (CPR) in the fifth and the sixth grade of elementary school students. Methods: The participants were 242 elementary school students from A city. Data were collected from August 26 to August 27, 2013 using a questionnaire. Data analysis was performed by SPSS/WIN 19.0 using ANOVA, t-test, Pearson correlation and stepwise multiple regression. Results: Factors affecting on self efficacy to CPR were attitude (${\beta}=.54$), religion (${\beta}=-.16$), recognition (${\beta}=.15$) and knowledge (${\beta}=.13$). These factors explain 47.0% of the variance in self efficacy. Conclusion: The results of this study show that attitude to CPR has the strongest influence on efficacy. Based on the results of this study, we suggest that customized programs and further research by using 2010 guideline are needed to develop for elementary school students.
