Airway + Breathing disorders CPR with AED Lukas Dadak, MD St. Ann's University Hospital, Brno Kamil Hudacek, MD University Hospital Brno BLS algorithm • Danger • Response = consciousness (AVPU scale) • Shout / Send for help • Airway = open it • Breathing • Circulation Primary Survey = 20s Choking Conscious Adult • uncommon but potentially treatable • less than 1% of these incidents are fatal - mostly witnessed • food partitions • trauma / burns • edema = swelling Choking Sings: • clutch throat or mouth • cough, gurgle, vomiting sound, wheezing • inability to speak • heavy breathing • anxiety • turns blue (cyanosis) from lack of oxygen • if breathing is not restored, the victim falls into unconsciousness Inability to relieve the obstruction can cause: • Breathing failure • Brain damage • Death Narrowest part of airway: Adult: glotis Child: subglotic space Foreign Body Airway Obstruction • relief FBAO = life saving procedure • safe, effective, simple • Cough and bend forwards • 5 Back blows / slaps • 5 Abdominal thrusts = (Heimlich maneuver) • Chest thrusts often you will need more than 1 procedure to clean the airway Mild obstruction • Coughing generates high and sustained airway pressures and may expel the foreign body. • Aggressive treatment, (back blows, abdominal thrusts, chest compression), may cause potentially serious complications and could worsen the airway obstruction. • Continuous observation until they – improve – severe airway obstruction may develop First aid: 155 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 up to five sharp blows between the shoulder blades with the heel of your other hand. Back blows Heimlich man. = abdominal thrust Increase pressure below foreign body • Stand behind the victim and put both arms round the upper part of his abdomen. • Lean the victim forwards. • Clench your fist and place it between the umbilicus and xiphisternum. • Grasp this hand with your other hand and pull sharply inwards and upwards. • Repeat up to five times Chest thrust • markedly obese persons • late stages of pregnancy Increase pressure under foreign body 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 First Aid - Choking - Adult & Child 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. Only remove dentures if loose or broken. • Use your 2 fingers only - if you see solid material in the mouth • Do not push fingers where you can not see Keep airway open head tilt, chin lift Esmarch maneuver / Jaw thrust BLS – breathing with face-mask Face mask ventilation Positive pressure ventilation by bag-valve mask  correct volume = movement of chest  Fr. 10/min  100% O2  1 hand hold:  inch + index f.  3 ff. - chin  2 hands Guedel airway Oro-Pharyngeal Airway I: unconsciousness + airway obstruction with tongue Correct size OPA:  distance angle of mouth --- ear Risk in mild unconsciousness:  vomitus + aspiration Naso-Pharyngeal Airway (trumpet) Correct size of NPA:  distance nostril --- ear Risk:  bleeding from nasal cavity  Use of lubricant is essential Chain of survival European resuscitation council Approximately 700,000 cardiac arrests per year in Europe Survival to hospital discharge presently approximately 5-10% Bystander CPR is vital intervention before arrival of emergency services Early resuscitation and prompt defibrillation (within 5 minutes) can result in >50% survival Automated External Defibrilator Ventricular fibrilation Most common cause of cardiac arrest in adults out of hospital - caused by obstructed coronary artery in myocardial infarction - electric shock is the only treatment Defibrilation in Czech provided by ambulance services or lay persons  continue with CPR Attach AED Follow voice prompts 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 Successful defibrillation - could wake up if shock applied until 5 min - starts to breath, cough Victim could be turned to recovery position – monitor vital signs till ambulance come Do not take the electrodes off !! RECOVERY POSITION If the affected person begins to breathe normally, turn him / her sideways to the recovery position Always check for breathing Do not remove the electrodes NO SHOCK ADVISED FOLLOW AED INSTRUCTIONS 30 : 2 http://www.fsps.muni.cz/aed/mapa/ TACPR Telephone Asisted CPR No consciousness, No breathing … Next person call 155 .. Open the green box by code given by phone. http://www.fsps.muni.cz/aed/videa/zelny-trh-dlouhe/ Precordial thump No more part of BLS !! (ERC guidelines since 2005) reserved :  witnessed cardiac arrest when no defibrillator is immediately available  if done in first 20s 25% regain cardiac function Thanks for your attention 142221@mail.muni.cz Hudacek.Kamil@fnbrno.cz
