Choking on something can easily become a very big problem, but quick action from a first aider can help prevent the situation from becoming more serious.

If a casualty begins to choke, first encourage them to cough - in a lot of cases a hearty cough is enough to dislodge whatever was stuck. 

If coughing doesn't work, begin to administer back blows - help support the casualty, and with the heel of your free hand give up to 5 back blows between their shoulder blades. Check if the obstruction has cleared between each blow.

If the obstruction hasn't cleared, give the casualty abdominal thrusts - standing behind them, place one hand in-between the casualty's belly button and the bottom of their breastbone. Put your other fist on top and pull sharply inwards and upwards.

Repeat this sharp motion up to 5 times, checking if the obstruction has cleared between each thrust.

Repeat 5 back blows and 5 abdominal thrusts up to 3 times. If the obstruction has still not cleared, call 999 and continue until help arrives.

If the casualty becomes unconscious, begin CPR immediately.
