Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary outcomes of this study are the mean chest compression depth (mm) and mean chest compression rate (n/min) for 2 minutes. The secondary outcomes are the proportions of adequate compression depth (%), adequate compression rate (%), adequate compression depth and rate (%), correct chest compression position (%), and compression with full release (%). According to the 2020 AHA Cardiopulmonary Resuscitation and Emergency Cardiovascular Care guidelines, adequate compression depth is defined as a compression of 50-60 mm, and adequate compression rate is defined as a rate of 100-120 compressions per minute. The correct chest compression position is measured using a manikin simulator to ensure that the lower half of the sternum is compressed accurately. If the location of chest compression is incorrect, the chest movement tilts instead of moving horizontally, and this is deemed as an incorrect compression.
Participant Enrollment Participants are recruited through a poster on the information board of a university, following IRB approval. The inclusion criteria for participants are adults aged over 18 years who are certified as AHA Basic Life Support (BLS) providers or have undergone equivalent BLS training. Applicants who meet the following criteria are excluded because they are judged unable to perform adequate chest compressions: (1) physical or cognitive disabilities and (2) musculoskeletal injuries, such as limb injuries. Additionally, as the study is conducted during the COVID-19 pandemic, individuals diagnosed with COVID-19, under quarantine, or experiencing fever or respiratory symptoms suspected to be COVID-19 are excluded.
The purpose of the study is explained to participants who meet the inclusion criteria, including their right to withdraw consent at any time. Participants then complete a written informed consent form to participate in the study.
Simulation Design Participants attend a brief educational session covering the theoretical content of chest compressions, including the importance of compression position, depth, rate, and full release. Education is provided following the 2020 AHA Cardiopulmonary Resuscitation and Emergency Cardiovascular Care guidelines. Additionally, the session includes an explanation of chest compression methods using both hands and feet.
After the educational session, participants are divided into a foot-hand group (F-H group) and a hand-foot group (H-F group) according to whether FCC or HCC is performed first, through random allocation. Participants are then moved to independent rooms (Room A for the F-H group and Room B for the H-F group).
This study uses a crossover design. Participants in the F-H group first perform training and testing using the FCC method and then perform training and testing using the HCC method, while participants in the H-F group follow the opposite order.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
F-H Group
Participants in this group perform training and testing using the foot chest compression (FCC) method first, followed by training and testing using the hand chest compression (HCC) method.
Foot Chest Compression
Foot chest compression is an alternative cardiopulmonary resuscitation (CPR) technique where the rescuer uses one foot to perform compressions on the chest instead of their hands. The heel of the foot is placed on the lower half of the sternum, with the foot parallel to the sternum to ensure effective pressure. The opposite foot provides stability by being positioned beside the patient.
Hand Chest Compression
Hand chest compression is the conventional method of performing chest compressions during CPR. It involves the use of both hands, with one hand placed over the other on the lower half of the sternum. The rescuer positions their body directly over the patient, using the weight of their upper body to deliver compressions of 50-60 mm depth at a rate of 100-120 compressions per minute. Proper technique includes full chest recoil between compressions, maintaining a straight arm posture, and avoiding pressure on the xiphoid process to minimize injury risks. This method adheres to the 2020 AHA guidelines for high-quality CPR.
H-F Group
Participants in this group perform training and testing using the hand chest compression (HCC) method first, followed by training and testing using the foot chest compression (FCC) method.
