You are health care provider at a hospital and you have successfully removed a coin from the trachea (windpipe) of a three-year old boy by

applying Heimlich's maneuver. You checked his respiration and found that he was breathing
normally. What do you do next?�

After successfully removing the coin and ensuring that the child's breathing is normal, the next steps would be to monitor the child closely for any signs of difficulty breathing or potential complications. It would be important to continue observing the child's breathing, heart rate, and overall condition.

Additionally, it would be important to inform the child's parents or guardians of the incident and provide them with instructions for monitoring the child at home. The parents should be advised to seek medical attention immediately if the child displays any signs of respiratory distress or difficulty breathing.

Lastly, it may be necessary to conduct further tests or evaluations to confirm that there are no additional coins or foreign objects lodged in the child's airway. This may involve performing a chest x-ray or other imaging studies to ensure that the airway is clear and there are no further obstructions.
