This paper aims to compare the effectiveness of the chest compression when a person pushes on the infant's chest by using two fingers with the support during infant cardiopulmonary resuscitation, with the effectiveness of it without the support, and to find which one is better. For the study, 50 college woman students were tested during the simulation and the result of the test has been analyzed by chi-square test, Fisher's exact test. In case of the chest compression by using the support, the depth of the chest compression comes to $3.73{\pm}0.33cm$. On the other hand, in case of the chest compression without the support, $2.50{\pm}0.59cm$. It is founded that the method of pushing on the chest by using the support is more effective than that without the support (p < 0.001). It is concluded that the way that a person pushes on the infant's chest by using two fingers with the support during infant cardiopulmonary resuscitation has turned out to be more effective and useful. It is thought that in the future, the further study for it should be conducted.

This study is to find out the effectiveness by Infant CPR method of a single rescuer. It was conducted for 51 general public. And typical infant CPR method by a single rescuer and a new method, CPR with two thumb chest compressions wrapped in both hands over the head were compared. SPSS 22.0 was used as an analysis method and to compare the both CPR methods, Paired t-test was used. As a result of the study, the average chest compression depth(39.38±1.07 mm) by CPR with two thumb chest compressions wrapped in both hands over the head was significantly high(p<0.001). Ease of mouth-to-mouth resuscitation(p<0.001), convenience of CPR method(p<0.001), and finger pain level(p<0.001) had a significant difference. As for the preference of the CPR method, 80.4%(41 people) preferred CPR with two thumb chest compressions wrapped in both hands over the head. In this study, CPR with two thumb chest compressions wrapped in both hands over the head showed more effective results than typical CPR method. However, as a virtual study using mannequins, further research is needed to apply high-quality CPR methods to field.

Cardiac arrest is a series of conditions occur when the heart is stopped, regardless of the cause. one of the only ways to save a patient's life in the event of cardiac arrest is cardiopulmonary resuscitation, which is very important beacause it can maintain circulation through this technique, and high-quality CPR affects the survival rate and neurological prognosis of the patient. For infant cardiopulmonary resuscitation, use two finger to compress the chest. Hower, this method can be diffcult to reach the chest commpressions recommended by the American Heart Association because of the anatomically increased fatigue of the fingers and diffculty of vertical pressure. The study aims to verify the effects of new chest compressions in the implementation of chest compressions during infant cardiopulmonary resuscitation. The study also showed singnificant differences in chest depth and average rate of pressure(p<0.001). Based on the results of this study, we can see that the accuracy of the new chest compressions during infant cardiopulmonary resuscitation is increased, and the depth of chest compressions is improved, improving the quality index of chest compressions.

This study is to find out the effectiveness by adult CPR method of a single rescuer. For patients with acute cardiac arrest, CPR is the only first aid, and chest compression is the most important of these techniques. The subjects of this study were freshman, 120 subjects who did not learn CPR, and for data analysis, the SPSS 22.0 Version was used. The accuracy of chest compression site selection was significantly higher in the upper part of the two fingers in the pit of the stomach(p<.001), and the ease was also high(p<.001). In the case of the general public, they select the chest compression area easily and quickly, it turns out that it is easier to designate the landmark toward the pit of the stomach. In the future, through various job groups, research to select the chest compression site is needed, and additional studies should be conducted to confirm the maintenance and accuracy during chest compression.

Acrodysostosis is an extremely rare disorder characterized by short fingers and toes with peripheral dysostosis, nasal hypoplasia, and mental retardation. We report a 16-year-old Korean boy with acrodysostosis who had characteristic clinical features and cervical spine stenosis manifested by neurologic symptoms. On presentation, he complained of difficulty in raising his arms, and suffered from intermittent pain and weakness in both upper extremities. He had short stature and dysmorphic facial features, including a broad, depressed nasal bridge, small, upturned nose, bilateral epicanthal folds, and mild hypertelorism. Moderate mental retardation and sensorineural hearing loss in both ears were also present. Radiological findings included broad, short metacarpals and phalanges with cone-shaped epiphyses, bilateral Madelung deformities, hypertrophied first metatarsals, and thickening of the calvarium. Magnetic resonance imaging findings included stenosis of the cervical spine, platybasia with compression into the cervicomedullary junction, and downward displacement of the cerebellar tonsils. Here, we report a case of acrodysostosis with symptoms and signs of cervical spinal stenosis first in Korea. If it is diagnosed in the early stages, possible life-threatening complications, including spinal canal stenosis, can be managed properly and permanent neurologic sequelae might be avoided. Therefore, it is important to consider acrodysostosis in the differential diagnosis of peripheral dysostosis.
