Choking Conscious Adult • uncommon but potentially treatable • less than 1% of these incidents are fatal When? • while eating • while playing (coins, toys) NOTE: narrowest place of airway: glotis / subglotic space First aid: Forein-Body Airway Obstruction • relief FBAO = life saving procedure • safe, effective, simple • Cough and bend forwards • Back blows/slaps • Abdominal thrusts = (Heimlich Maneuver) • Chest thrusts • often you will need more than 1 procedure to clean airway Heimlich man. = abdomen thrust chest thrust may be used for markedly obese persons or in late stages of pregnancy Back blows bend forwards ● 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 up to five sharp blows between the shoulder blades with the heel of your other hand Following successful treatment: Victims with a persistent cough, difficulty swallowing or the sensation of an object being still stuck in the throat should be examined ● Abdominal thrusts can cause serious internal injuries ● all victims treated with abdominal thrusts should be examined for injury by a doctor Clear airway if necessary during coma • with the casualty supported on the side, tilt the head backwards and slightly down. • Open the mouth and clear any foreign object.

When stop CPR: - restoring vital functions - ER takes care of victim - no power to continue with CPR - new danger Precordial thump Not part of BLS reserved : ● witnessed cardiac arrest when no defibrillator is immediately available ● if done in first 20s 25% regain cardiac function Defibrilation in Czech provided by ER ● continue with CPR Start of AED ● Some AEDs will automatically switch themselves on when the lid is opened ATTACH PADS TO CASUALTY’S BARE CHEST ANALYSING RHYTHM DO NOT TOUCH VICTIM SHOCK INDICATED ● Stand clear ● Deliver shock SHOCK DELIVERED FOLLOW AED INSTRUCTIONS 30 : 2 NO SHOCK ADVISED FOLLOW AED INSTRUCTIONS 30 : 2
