The keys to survival from sudden cardiac arrest (SCA ) are: recognition and treatment, specifically, immediate initiation of excellent CPR and early defibrillation. Cardio Pulmonary Resuscitation CPR is an emergency first -aid procedure that is used to maintain respiration and blood circulation in a person, whose breathing and heartbeats have suddenly stopped. Involves a series of immediate actions to take to restore the flow of oxygenated blood to a person's brain and organs when they suffer Sudden Cardiac Arrest ( SCA ). Chain of survival Chain of survival Cardio Pulmonary Resuscitation Three basic vital functions: Breathing Circulation Consciousness Cardio Pulmonary Resuscitation Thoracic pump theory - the chest compression propels blood out of the thorax by increasing intrathoracic pressure the time of the chest compression and decompression should be equal Pressure should be completaly released Hands should remain in the contact with the chest CardioPulmonary Resuscitation Oxygene content In atmospheric air - 21% In alveoli - 14,5% Expired air diluted by air from the airways (dead space) 16 18 % O2 At best chest compressions provide only 30% of normal perfusion brain + heart Time! Time! Time! Time! Time! Time! Time! Time! Failure of the circulation 3 - 5 minutes irreversible cerebral damage. Chances of successful CPR - restoration of spontaneous circulation (ROSC) decreases by 10% with each minute following sudden cardiac arrest Indication of CPR to victims with unexpected cardiac arrest in otherwise healthy individuals to those, who can be described as having heart too good to die CONDUCTING BLS This will be conducted basing on the guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care The guidelines are published jointly by the > International Liaison Committee on > Resuscitation, > American Heart Association, and > European Resuscitation Council. The Algorithm Performance of excellent chest compressions Most important element of CPR The mantra of the CPR -ECC Guidelines was: "push hard and push fast on the center of the chest To perform excellent chest compressions, the rescuer and patient must be in optimal position The patient must lie on a firm surface - may require a backboard on a bed or the patient should be placed on the floor Place the heel of one hand in the center of the chest over the lower ( caudad ) portion of the sternum and the heel of their other hand atop the first. The rescuer's own chest should be directly above their hands to enable them use their body weight to compress the patient's chest, rather than just the muscles of their arms, which may fatigue quickly. Performance of excellent chest compressions Copyrights apply Goals For Excellent ## chest compressions 100 to 120 compressions / minute Compress the chest at least 5 cm (2 inches) but no more than 6 cm (2.5 inches) with each down -stroke Allow full recoil of chest wall Change over every 2 minutes (if poss .) but m inimize the frequency and duration of any interruptions 30:2 ratio (compression / ventilation) Compression only much better than nothing Ventilation Open airway (head tilt, chin lift, jaw thrust) Check for normal breathing Agonal gasps = not normal! Watch for chest movement In hospital: bag / mask (laryngeal mask) The importance of compressions supersedes ventilations Properly performed ventilations become increasingly important as pulselessness persists Give each ventilation over no more than one second Give two ventilations after every 30 compressions, discontinuing compressions during the ventilations Avoid excessive ventilation (rate or volume ) 10 breaths per minute is recommendable, however, 6 to 8 breaths are adequate Proper Ventilation MOUTH TO MOUTH ADJUNCT Mouth to mouth in adults Defibrillation is the non -synchronized delivery of a shock during the cardiac cycle . This can done using an AED or normal defibrillator As soon as a defibrillator is available, assess the cardiac rhythm and, when indicated, perform defibrillation as quickly as possible . For BLS, a single shock when prompted from an automated external defibrillator ( AED) is delivered followed immediately by the resumption of excellent chest compressions . ## Defibrillation Defibrillation COMPLICATIONS OF CPR Injuries caused by CPR can be of a concern. More frequent when incorrect technique is employed. However, injuries from chest compressions can occur despite excellent technique. Some may include: > Rib and sternal fractures > Cardiac and pulmonary contusions > Pneumo -and hemothorax > Intra -abdominal trauma Despite the possibility of such complications, the risk of withholding potentially lifesaving treatment from a patient in cardiac arrest is far exceeded by the potential benefit of brain -saving resuscitation Mouth to mouth in children Chest compressions in children Chest compressions in very young children CHOKING Choking occurs when a foreign object lodges in the air way, blocking the flow of air. In adults, a piece of food often is the culprit. Young children often swallow small objects. Because choking cuts off oxygen to the brain, give first aid as quickly as possible. You will know that someone is choking when hands are clutched to the throat. Other signs could be: Inability to talk Difficulty breathing or noisy breathing Squeaky sounds when trying to breathe Cough, which may either be weak or forceful Skin, lips and nails turning blue or dusky Skin that is flushed, then turns pale or bluish in color Loss of consciousness Tachypnea Inspiratory stridor, wheezing Suprasternal or supraclavicular retractions Prolonged inspiratory phase Drooling Dysphagia Positions of comfort to help maintain airway patency in patients with severe obstruction: "Sniffing" position (neck is mildly flexed and head is mildly extended) Tripod position (leaning forward while bracing on the arms with neck hyperextended and chin thrust forward) Give 5 back blows. Stand to the side and just behind a choking adult. For a child, kneel down behind. Place one arm across the person's chest for support. Bend the person over at the waist so that the upper body is parallel with the ground. Deliver five separate back blows between the person's shoulder blades with the heel of your hand. Give 5 abdominal thrusts. Perform five abdominal thrusts (also known as the Heimlich maneuver). Alternate between 5 blows and 5 thrusts until the blockage is dislodged. To perform abdominal thrusts (Heimlich maneuver) on someone else: Stand behind the person. Place one foot slightly in front of the other for balance. Wrap your arms around the waist. Tip the person forward slightly. If a child is choking, kneel down behind the child. Make a fist with one hand. Position it slightly above the person's navel. Grasp the fist with the other hand. Press hard into the abdomen with a quick, upward thrust as if trying to lift the person up. Perform between six and 10 abdominal thrusts until the blockage is dislodged.
