A conscious adult choking victim may not be able to talk, cough, or breathe, and may do the universal choking sign with hands around their throat. Ask if the patient needs help.
Once you have established that the victim is choking, stand behind them with one arm under their arm supporting against their stomach. Lean them forward and with your other hand perform up to 5 back blows between the shoulder blades.
If this is unsuccessful, then separate the patient’s feet, place one foot behind their feet, and raise their elbows. Place one hand with the thumb tucked in against the abdomen, above the belly button and grab your fist with the other hand. Perform abdominal thrusts five times. Check to see if the obstruction is out. If not, repeat the same steps, with five back blows and five thrusts, until the object comes out of the patient’s airway or the patient becomes unconscious.
If the patient is pregnant or markedly obese use chest thrusts instead of abdominal thrusts.
Never attempt this unless someone actually needs it and it is recommended in all cases for them to get checked out by a medical professional.
