Measurement of the Quality of Pediatric CPR (PediQ-CPR)

• Determine the existing quality of CPR performed during the resuscitation of children 1year to less than 8 years of age. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  

• Determine the chest wall stiffness of children in order to improve quantitative CPR modeling efforts and to facilitate the construction of more biofidelic pediatric manikins for CPR simulation and test dummies for automotive safety. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  

Device: There is no intervention for this study.
There is no intervention for this study. The pre-NSR IDE for this study is simply a modification to allow for recording of data without intervention.

In the event of a cardiac arrest in the pediatric intensive care unit, a 24 hour paging system will notify the Cardiac Arrest Research Team to facilitate data collection. This system has been active as part of The Children's Hospital of Philadelphia (CHOP) Institutional Review Board (IRB) Protocol No. 2006-6-4839, and has resulted in capture of more than 95% of eligible events.

Cardiac arrest events requiring chest compressions in the PICU (pediatric intensive care unit) involving children greater than or equal to 1 year of age, but less than 8 years of age and who were previously screened, identified, and who have provided written consent are eligible for study. CPR quality will be recorded with the modified Heartstart MRx with Q-CPR Option, an external defibrillator with a chest compression sensor interposed between the hands of the rescuer providing chest compressions and the sternum of the patient. The device to be used is a regular Heartstart MRx with Quality of CPR (Q-CPR) Option cleared under 510(k) Premarket notification - K051134, but which has been modified for this study. In its current version, Q-CPR Option is approved for patients ≥ 8 years of age and has been utilized in the CHOP Pediatric Intensive Care Unit (PICU) under CHOP IRB Protocol No. 2006-6-4839. This Q-CPR Option on the Heartstart MRx has been modified for this study to accommodate children 1 year to less than 8 years of age. Since the device has been modified for use in this study, the device is an Investigational Device during this study regulated by the IDE regulation (CFR 21 Part 812). FDA has determined through a pre-investigational device exemption (IDE) process (I090674) that the use of the Heartstart MRx with the modified Q-CPR Option in a non-significant risk (NSR) device study. Two primary modifications were done on the Q-CPR Option: 1) changing the size of the compressions sensor footprint that interfaces with the patient's chest and 2) disabling the audiovisual Q-CPR feedback. Specifically the contact area of the compression sensor has been reduced to better mimic the area of the heel of a hand - the current recommended interface between the CPR administrator and the patient's chest during usual CPR / resuscitative care. Furthermore, no audiovisual feedback will be provided for this patient group as absolute measurement-based CPR quality targets do not exist for this age group. The device records CPR parameters (depth and rate of chest compressions), as well as electrocardiographic (ECG) data, and defibrillation shock data (if used). The pad relays this information to a recording component on the defibrillator which stores such data onto an internal data card. Once the cardiac arrest is completed, the MRx data can be exported to an external data card and downloaded to a secure laptop.

The investigator will use the Study Data Collection Form I in the Appendix to collect additional information immediately after resuscitation event has concluded. The patient's medical record will also be accessed and data will be collected as specified in the Medical Record Data Collection Form II. In addition to medical information, data collected will also include the post arrest chest depth in centimeters (cm) of the patient, chest circumference (cm) and details of the mattress and bed on which the child was resuscitated. Phase 2 procedures will be identical to those employed as per CHOP IRB Protocol No. 2006-6-4839.
