Abstract

|
|
Purpose : The purpose of the study is to investigate the quality and relevance of back strength or chest compression which is applied by isotonic exercise of hip joint.
Methods : Subjects were 37 students who participated in the BLS course and accepted the informed consent from December 7 to 8, 2012. During CPR performance, back strength was measured by the researcher. CPR was used the manikin for practical training with using PC, conducted by standard CPR for 2 minutes,Quality of chest compressions included average chest compression depth, rate, and recoil ratio.
Results : Back strength (kg) is related to the chest compression depth (mm) (r =.746, p <.001). The high quality CPR is the most important factor so high quality is full chest recoil of chest compression and chest compression depth (mm) (β=.831, p <.001). In this study, chest compression rate and recoil ration were not influenced by back muscle strength.
Conclusion : It is necessary to implement the CPR program to improve physical strength and effective performance of CPR.
