Airway obstruction can lead to respiratory and cardiac arrest if not addressed quickly and effectively. A conscious patient clutching his/her throat is showing the universal sign of choking.
Resuscitation Council (UK) Resuscitation Guidelines 2015 Guidelines:
“GIVE BACK BLOWS"
If cough becomes ineffective give up to 5 back blows
Stand to the side and slightly behind the victim
Support the chest with one hand and lean the victim well forwards so that when the obstructing object is dislodged it comes out of the mouth rather than goes further down the airway
Give five sharp blows between the shoulder blades with the heel of your other hand
GIVE ABDOMINAL THRUSTS
If back blows are ineffective give up to 5 abdominal thrusts
Stand behind the victim and put both arms round the upper part of the abdomen
Lean the victim forwards
Clench your fist and place it between the umbilicus (navel) and the ribcage
Grasp this hand with your other hand and pull sharply inwards and upwards
Repeat up to five times
If the obstruction is still not relieved, continue alternating five back blows with five abdominal thrusts
Start CPR if the victim becomes unresponsive
Support the victim carefully to the ground
Immediately activate the ambulance service
Begin CPR with chest compressions
If the patient becomes unresponsive, immediately begin CPR with chest compressions and make sure an AED is readily available. Each time the airway is opened to give ventilations, look for any visible objects in the oropharynx. If an object can be seen, remove it (if possible) using a finger sweep motion (Figure 8). If a foreign object is not visible, a blind finger sweep should not be performed; continue CPR, cycles of 30 compressions and 2 ventilations, until EMS arrives.
