Final answer:
To help a conscious choking infant, administer 5 back blows and 5 chest thrusts, call for emergency medical help, and perform CPR if the infant becomes unresponsive. Administer mouth-to-mouth resuscitation if necessary.
Step-by-step explanation:
If you encounter a conscious choking infant who cannot cough, cry, or breathe, you should follow specific first aid procedures to assist them. First, it is important to give 5 back blows by holding the infant face down on your forearm, supported by your thigh, and using the heel of your hand to give sharp blows on the back between the shoulder blades. If this does not dislodge the object, proceed with 5 chest thrusts, flipping the infant over and pressing downwards in the middle of the chest with two fingers. These steps can be repeated until the object is removed or the infant starts to breathe or cough.
Call for emergency medical help or direct someone else to do so immediately if you suspect a severe choking incident. If the infant becomes unresponsive, you should begin CPR (with compressions and rescue breaths) and continue until help arrives or the infant recovers.
Administer mouth-to-mouth resuscitation if the infant is not breathing after the object has been cleared or if they are unresponsive. Mouth-to-mouth is given by covering the infant's mouth and nose with your mouth and giving gentle breaths.
