Anaphylaxis in Children

Medically reviewed by Last updated on Jan 5, 2023.

Anaphylaxis is a life-threatening allergic reaction that must be treated immediately. Your child's risk for anaphylaxis increases if he or she has asthma that is severe or not controlled. Medical conditions such as heart disease can also increase your child's risk. It is important to be prepared if your child is at risk for anaphylaxis. Symptoms can be worse each time he or she is exposed to the trigger.

An ECG records your child's heart rhythm and how fast his or her heart beats. It is used to see if your child's heart is beating normally.


  • Oxygen may be needed if your child's blood oxygen level is lower than it should be. Your child may get oxygen through a mask placed over his or her nose and mouth or through small tubes placed in the nostrils. Ask your child's healthcare provider before you take off the mask or oxygen tubing.
  • A ventilator is a machine that gives your child oxygen. It breathes for your child when he or she cannot breathe well on his or her own. An endotracheal tube (ET) is put in your child's mouth or nose and attached to the ventilator. Your child may need a trach if an ET tube cannot be placed. A trach is a tube that is put through an incision and into your child's windpipe then attached to the ventilator.
