Signs of choking (complete airway obstruction)

A person who is choking (has complete airway obstruction):

  • Can't cry, talk, breathe, or cough.
  • May grasp throat.
  • May become severely anxious or agitated.
  • May turn blue or dusky in colour.
  • May pass out.

A choking rescue procedure (the Heimlich manoeuvre) is used to clear an obstruction in adults and children older than 1 year. Back blows and chest thrusts are used in babies younger than 1 year.
