Final answer:
If you are alone and find an unresponsive infant, the first step is to check if the baby is breathing. If not, immediately start CPR and call emergency medical services.
Step-by-step explanation:
If you are alone and find an unresponsive infant, the first thing you should do is check if the baby is breathing. You can do this by looking for any movement or signs of breathing, such as chest rising and falling. If the baby is not breathing or is only making gasping sounds, immediately start CPR (cardiopulmonary resuscitation). This involves giving chest compressions and rescue breaths to help circulate oxygen in the baby's body until medical help arrives.
Remember to call emergency medical services right away for professional help. It is important to continue CPR until medical professionals arrive and take over.
It's crucial to receive proper training in infant CPR to be prepared for such situations, as incorrect techniques can be harmful. Consider taking a certified CPR course or seeking guidance from medical professionals for the most accurate and reliable information.
