Quality of Pediatric Resuscitation Study is focused on understanding how well CPR (cardiopulmonary resuscitation) works in children. CPR is a life-saving technique used when someone's heart stops beating. This study checks how CPR quality, like the speed and depth of chest pushes, affects kids' recovery. It also looks at how care after a heart stops affects recovery. The study collects data when CPR is given in hospitals to children aged from birth to 17 years old.

• **Length**: The study observes children's CPR in hospital without changing their treatment.
• **Visits**: No extra visits are needed, as it occurs during hospital care.
• **Compensation and Risks**: No compensation or extra risks, as it uses regular hospital data.

To join, children must have had CPR for at least one minute and use a device to measure CPR's quality. Kids on ECMO (a special heart-lung machine) at the start of CPR can't join. The goal is to help improve how CPR is done and make sure children have better outcomes after their hearts stop.
