Five pushes on the chest with two fingertips. First aid for infant choking You may see an infant choke on food. Or you may suspect choking if an infant collapses while eating or putting things into her mouth. An infant with a completely blocked airway cannot breathe, cough or cry. If the airway is almost completely blocked, there are high-pitched noises when inhaling, great difficulty breathing, and very weak or no coughing.
First aid is the same for a completely blocked airway and an almost completely blocked airway.
The basic steps for removing an object from the airway of an infant are back blows and chest thrusts. DO NOT do this if baby can breathe, cough or cry. Lay the baby on top of your arm, with her head lower than her chest. Support baby's head with your hand around the jaw and under the chest. Rest your arm on your thigh.
