In which situation should you stop CPR for a child in respiratory failure?

The recommendation to stop CPR when there is improvement in perfusion is based on the key objective of performing CPR, which is to restore effective blood circulation and oxygenation to vital organs. Improved perfusion indicates that the heart is beginning to pump effectively again, allowing for adequate blood flow.

When assessing a child in respiratory failure, signs of improved perfusion may include a return of a good pulse, an improvement in skin color (from blue or pale to a healthy pink), or better responsiveness. These are essential indicators that the body's vital functions are beginning to stabilize.

Continuing CPR without assessing these signs could result in unnecessary interventions when recovery is underway. It's important to ensure that the child is transitioning towards stability before ceasing life-saving measures.
