Chocking
Choking can occur when a solid or small object enters a narrowed part of airway and becomes stuck.
On inhalation, object can be drawn tighter in and block air from entering lungs, a forceful thrust beneath ribs and up into diaphragm can pressurize air in chest and pop obstruction out. Chest compression over the breastbone can create enough pressure to expel an object.
Mild Obstruction
Severe Obstruction
In severe obstruction, a person cannot take in enough air to dislodge the object. Signs of severe obstruction include;
- Very little or no air exchange
- Lack of sound
- Inability to speak or cough forcefully
- Person may hold his or her hands to the throat while attempting to clear obstruction
A Person without air exchange requires your help to survive.
Children and infants
Approach for child nearly the same as for adult,
- Kneel behind child to deliver thrusts
- Use less force
- Weak ineffective coughs
- Lack of sound even when attempting to breathe
Approach for Infant
Assess Infant • Look at infant’s face • If infant has weak, ineffective coughs, or lack of sound even when clearly attempting to breathe, act quickly • If available, have a bystander activate Emergency Medical Service (EMS).
Give 5 Back Blows • Lay infant face down over your forearm with legs straddled and with head lower than the chest. Support the head by holding the jaw. • Using heel of other hand, give 5 back blows between shoulder blades.
Give 5 Chest Thrusts • Sandwich infant between your forearms and turn onto back. • Place 2 fingers on breastbone just below nipple line and give 5 chest thrusts • Repeat back blows and chest thrusts until infant can breathe normally.
If infant Unresponsive • Gently place infant on firm surface • If alone, provide 2 minutes of CPR before activating EMS yourself • Look into the mouth before giving rescue breaths. Remove any object seen • Continue CPR until signs of life, or another provider or EMS personnel take over
