Cardiopulmonary resuscitation(CPR) is performed by artificial ventilation and thoracic compression for the patient under emergent situation to maintain at least the minimum level of respiration and blood circulation for life survival. Good quality CPR requires monitoring respiration. We developed a system for continuous monitoring respirational signal while CPR, using respirational airflow sensor for CPR. Signal extraction circuit obtains pressure signal while CPR. Obtained signal would be performed analog-digital conversion and changed to airflow value by characteristic formula. Single inspiration and expiration were considered a period. Detected valid data were displayed LCD.

Purpose: In order to elucidate the effects of BLS (Basic Life Support) education for primary students, we analyzed data collected using a questionnaire on attitude toward CPR. Methods: Students were divided into two groups, the experimental group with BLS education and the control group without BLS education. Data was collected after BLS education for the experimental group. While they were learning BLS, the control group completed the questionnaire. Results: There were significant statistical differences in the total score of students' attitudes. The students in the experimental group indicated a more positive attitude toward CPR than the others. Conclusion: This study showed that BLS education had a positive influence on elementary students' attitudes toward CPR. We expect that the result will contribute to the spread of CPR and the reduction of mortality.

Background: This study evaluates the existing cardiopulmonary resuscitation (CPR) knowledge and skills of 1 st year dental students and also compares their CPR performance skill with those of 4 th year students. Methods: Incoming 1 st year and 4 th year dental students were surveyed about the level of their CPR knowledge before conventional CPR instruction. After we trained them for CPR performance, we tested CPR performance skill to randomly selected 10 1st year and 4 th year dental students and compared their CPR performance. Results: Overall CPR knowledge was low for both 1 st and 4 th year dental students. Especially, only 1 among 89 fourth year dental students answered the right sequence of CPR revised in 2010. Overall CPR performance was relatively low for both 1 st and 4 th year dental students. Irrespective of previous experiences of CPR education, their CPR performance was not statistically different. Conclusions: Retraining of CPR is a necessity. Information about the existing CPR knowledge for dental students will aid in establishing the goal of future CPR training and improve the current deficiency.

Aconitum is an extremely dangerous plant that contains various toxic diterpenoid alkaloids, primarily concentrated in the roots. We report a case of acute intoxication of a 60-year-old man admitted to our emergency department after ingestion of a large amount of homemade aconitine decoction. At presentation about one hour after intake, the patient was unconscious and electrocardiographic analysis showed a ventricular tachycardia/fibrillation. Several times defibrillation was applied and antiarrhythmic agents were administered, but the patient still exhibited a refractory ventricular fibrillation and failed to return to spontaneous circulation. Sustained cardiopulmonary resuscitation finally produced a pulsatile cardiac rhythm at two hours after intake. The patient was discharged from our hospital on day 8. The authors stress that clinicians must be aware of the possible occurrence of life-threatening ventricular arrhythmia in cases of aconitine intoxication and be prepared to persist with prolonged CPR as necessary.

Purpose: This study was conducted to determine effective chest compression methods that could be used when performing cardiopulmonary resuscitation in rocking boats. Methods: Tests were conducted for four minutes using manual and mechanical chest compressions on two mannequins, placed in boats, and moving at a speed of 35km/hours on calm sea surfaces with wave heights of 0.5m and wind speeds of 2-3m/s (testing for two minutes, followed by rest, then a second round of testing for two minutes). To compare the quality of the chest compressions, data were analyzed using mannequins (Resusci Anne Q-CPR, Laerdal, Norway) and then statistically processed. Results: When chest compressions were administered in the moving rescue boat, an accuracy analysis showed that the pressure speed of the hand and mechanical techniques were normal, h owever, the pressure depth accuracies were 49.04% for manual techniques and 0% for mechanical techniques. The relaxation accuracies during compressions were 2.07% for manual techniques and 95.4% for mechanical techniques. Conclusion: When administering chest compressions in rocking rescue boats, mechanical rather than manual techniques should be preferentially considered.

This study is to develop a basic life support (BLS) app using the android based smartphone and to evaluate the function of the app. Suggested app contains chest compression feedback function, the map of automated external defibrillator (AED), direct emergency call and the basic knowledge of BLS. Using the accelerometer of the smartphone, we implemented a real-time algorithm that estimates the chest compression depth and rate for high quality cardiopulmonary resuscitation (CPR). The accuracy of algorithm was evaluated by manikin experiment. We made contents which were easy to learn the BLS for the layperson and implemented a function that provides the AED location information based on the user's current location. From the manikin experiment, the chest compression depth and rate were no significant differences between the manikin data and the app's feedback data (p > 0.05). Developed BLS app was uploaded on Google Play Store and it was free to download. We expected that this app is useful to learn the BLS for the layperson.

배경: 고려대학교 흉부외과학교실에서는 심폐소생술에서 인공심 사용이 기존의 표준 심폐소생술에 비해 나은 결과를 보인다는 점에 착안하여 한국형 이동식 심폐소생기를 개발하고자 하였다. 1997년 1월부터 8월까지 한국형 이동식 심폐소생기 개발의 전단계로 심폐정지 모델 결정 및 표준 폐쇄식/ 개흉식 심폐소생술의 비교와 관찰지표 설정을 위한 준비실험을 실시하였다. 대상 및 방법: 실험은 한국산 잡견 9마리(28-35kg)를 대상으로 폐쇄식 심폐소생술군 4마리와 개흉식 심폐소생술군 5마리로 나누어, 4분 간의 심정지 및 15분간의 일차 심폐소생술(basic life support; BLS)과 30분간의 이차 심폐소생술(advanced life support; ALS)을 실시하였다. 심장압박은 폐쇄식군의 경우 흉부에 압박을 가하였고 개흉식군에서는 직접 심장을 맛사지하였다. 소생술기간에 양군 모두 동일한 조건의 폐환기 상태를 유지하였으며, 자발성 순환회복은 이차심폐소생술 기간 초기부터 재세동과 에피네프린 및 탄산수소 나트륨을 투여하여 유도하였다. 결과: 심폐소생술 기간안에 평균 체동맥압은 BLS 동안 폐쇄식군이 33$\pm$11 mmHg인데 비해 개흉식군은 45$\pm$15 mmHg로 높게 유지되었으며, ALS 동안에도 폐쇄식군 44$\pm$15 mmHg에 비해 개흉식군이 83$\pm$36 mmHg로 높게 유지 되었으나 통계상의 유의성은 없었다. 한편 평균 폐동맥압은 BLS 동안 폐쇄식군에서 32$\pm$10 mmHg로 평균 체동 맥압과 비슷한 정도로 증가하였으나 개흉식군은 22$\pm$4 mmHg로 평균 체동맥압의 약 50%정도까지만 증가하였고, ALS 동안에도 폐쇄식군은 32$\pm$15 mmHg로 개흉식군의 24$\pm$10 mmHg보다 높게 유지되었으나 통계처리상 유의성 은 없었다. 자발성 순환회복(restoration of spontaneous circulation; ROSC) 및 심폐소생 성공 여부에서 폐 쇄식군은 4마리 모두 사망하였으나 개흉식군은 5마리중 4마리가 생존하였고 생존기간은 384$\pm$705시간이였다 (p<.05). 결론: 본 연구 결과 개흉식 심폐소생술은 폐쇄식 소생술에 비해 비록 통계학상의 차이는 없었으나 소생술 기간 동안 비교해서 안정된 혈역학 상태를 유지하여서 자발성 순환회복 및 장단기 생존율을 향상시킬 수 있었다고 판단된다.

심폐소생술 가이드라인에서는 효과적인 가슴압박을 강조하지만, 구조자들이 가슴압박을 시행하는 것과 관련한 피로에 대해서는 적절히 다루지 않는다. 본 연구에서는 건강한 소방대원들을 대상으로 마네킨에 심폐소생술을 여러 사이클을 수행한 후에 보일 수 있는 증상, 혈역학적 상태, 그리고 심전도 등을 측정하였다. 연구 대상자의 활력징후, 심전도, 주관적 피로도 점수를 심폐소생술 시작 전, 심폐소생술 5주기 후, 10주기 시행 후에 측정하였으며, 심폐소생술 후 나타나는 증상에 대해 설문하였다. 39명의 연구 대상자들의 평균 연령은 $35.54{\pm}10.26$세이었으며, 심폐소생술 후 피로와 숨가뿜, 어지러움 등을 호소했다. 심폐소생술 시작 전, 5주기 후, 10주기 후 심박수, 호흡수, 호기말이산화탄소, 산소포화도, 맥압에서 유의한 차이를 보였으며, 1명의 참가자에서 심페소생술 10주기 후 부정맥이 나타났다. 본 연구 결과 지속적인 심폐소생술은 건강한 성인들에서 피로와 혈역학적 변화 등을 초래할 수 있다고 판단되며, 심폐소생술 가이드라인 및 교육에서는 장시간 심폐소생술을 하는 경우 구조자들에게 미칠 수 있는 영향에 대한 적극적인 안내가 필요하다.
