Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if the use of a metronome improves chest compression rate and depth during cardiopulmonary resuscitation (CPR) on a pediatric manikin.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be conducted in the simulation laboratory at Miami Children's Hospital. Chest compressions will be performed on a compression pediatric simulator. It will consist of two main groups randomly assigned to chest compressions without an audible metronome and chest compressions with audible metronomic tones that beep 100 times per minute for chest compressions. The metronome will be used to coach the correct rate. The same people will complete both arms of the study at one visit. Specifically, the participants will do 2 minutes of chest compressions followed by a 15-minute break then another 2 minutes of chest compressions (to avoid fatigue) with an acceptable range for rate 90-110 BPM and depth of 38-51mm. The subjects will be informed about the metronome, but will not be informed about the measured variables, such as rate and depth of chest compressions. However, the participants will be reminded at the beginning of their visit about the PALS card, i.e. appropriate rate and depth. The use of "talking people noise" from YouTube will be played in the background to fully model a cardiac arrest scenario (to see if participants ignore the metronome) and will be used during each group session. A noise dosimeter will be used to ensure this noise level is the same for each scenario. The manikin's airway will be secured with an endotracheal tube with continuous ventilations so chest compressions can be continued without interruption. Recommendations for chest compression rate and depth are per Pediatric Advanced Life Support (PALS) according to the 2010 American Heart Association (AHA) guidelines.

Data will be collected via the manikin which will wirelessly transmit the data (chest compression rate and depth) to a computer. The manikin has CPR sensing and recording technology software built in. This software records sternum movement depth and rate of chest compressions. Criteria for adequate CPR quality are defined as compression rate between 90-110 per minute and compression depth between 38-51mm.
