Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Pediatric cardiac arrests result in poor outcomes. Effective chest compressions improve survival in such patients. Unfortunately, compressions are generally inadequately performed and the quality of compressions given deteriorates rapidly with time. Current American Heart Association (AHA) guidelines call for faster and deeper chest compressions with minimization of interruptions. The effect of fatigue on operational performance while adhering strictly to these AHA guidelines is unknown. In addition, there is little pediatric data on rescuer fatigue and chest compression deterioration. Also, the use of a stepstool may affect the quality of chest compressions and may also have an impact on the fatigue of the rescuer. Understanding the biomechanics during optimal chest compression performance may prove useful in the recommendations of conditions and equipment for execution of more effective chest compressions during a cardiac arrest. We will aim to observe and understand the biomechanical qualities that allow for the most effective compressions.
Objectives:
1. To determine whether the quality of chest compressions deteriorates at the same rate in pediatric models as compared to adult models. To determine the relationship between physiologic/metabolic markers of work in rescuers and chest compression deterioration.
2. To determine the effect of stepstool use on the quality of chest compressions and metabolic demand. To determine whether the quality of chest compressions deteriorates at the same rate in participants using a stepstool compared to those not using a stepstool.
Study Design/Setting/Participants:
This prospective, randomized experimental trial will be performed at the Children's Hospital of Philadelphia. Participants will be healthcare practitioners who routinely provide chest compressions in the course of their work. Lay practitioners will be excluded.
Study Measures:
Participants will be asked to perform continuous chest compressions on pediatric and adult sized manikins. Compression rate, depth, applied force as well as participant physiologic work efficiency and anaerobic threshold will be recorded. To evaluate the second objective, a new cohort of participants will perform continuous chest compressions on an adult sized manikin with and without a stepstool.. Compression rate, depth, applied force as well as participant physiologic work efficiency and anaerobic threshold will also be recorded. Videotaping of each subject will also be used for comparison of subjective assessment of chest compression quality and objective chest compression quality data.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Adult vs Pedi manikin CC quality
The primary objective is to determine whether chest compression deterioration occurs at the same rate in pediatric and adult manikins. The primary endpoint will be the difference in mean number of effective compressions per minute in each manikin at times 1, 2, 5 and 10 minutes.
Another objective is to identify the correlation between the anaerobic threshold and the deterioration of compressions in each manikin. The endpoint will be the difference between mean time to ineffective compressions (defined as 10 consecutive compressions that fail to meet AHA guidelines for depth and rate) and mean time to anaerobic threshold in each manikin.
Chest compression on adult and pedi manikins
Each participant will be required to perform chest compressions on all 2 manikins, one on each of 2 assigned days. Participants will be randomized to one of 2 groups differing only in the order of manikins compressed, i.e. pediatric-adult; adult-pediatric, etc.
Stepstool use
A third main objective is to determine the effect of the stepstool use on the quality of chest compressions and metabolic demand. The endpoint will be the difference between mean time to ineffective compressions (defined as 10 consecutive compressions that fail to meet AHA guidelines for depth and rate) and mean time to anaerobic threshold in each experimental group.
Use of stepstool during chest compressions
In the additional arm of the study, a new cohort of participants will use only the adult manikin on two separate sessions. Participants will be randomized to one of two groups differing only in the use of a stepstool.
