To perform this maneuver on an adult, kneel above the patient's head Simultaneous Breathing and Pulse Check Once the airway is open, simultaneously check for breathing and a carotid pulse, for at least 5 but no more than 10 seconds. Agonal Breaths isolated or infrequent gasping that occur in the absence of normal breathing in an unconscious patient. How many ventalations and how often for patient in respiratory arrest? Give 1 ventilation every 5 to 6 seconds myocardial infarction myocardial infarction heart attack refers to the necrosis (death) of heart tissue as a result of a loss of oxygenated blood. Abandonment Discontinuing care once it has begun. Abdominal thrusts Inward and upward thrusts just above the navel to force an object out of the airway when a person is choking.

Assess, Recognize and Care Concept A systematic, continuous approach for quick and accurate assessment, rapid recognition and immediate care in emergency situations. Automated external defibrillator (AED) A portable electronic device that automatically analyzes a patient's heart rhythm and provides defibrillation, an electrical shock that may help the heart re-establish a perfusing rhythm; delivers defibrillation to patients with ventricular fibrillation and ventricular tachycardia. Back blows Blows between the scapulae to force an object out of the airway when a person is choking. Bag-valve-mask (BVM) resuscitator A handheld device used to ventilate a patient through the delivery of ambient air, thereby providing a 20% to 21% concentration of oxygen. Battery The unlawful, harmful or offensive touching of a patient without the patient's consent. Capnography A noninvasive way of measuring end-tidal carbon dioxide (CO,) level.

Chest compression During chest compressions, you press down on the person's chest. This squeezes (compresses) the heart between the breastbone (sternum) and spine, moving blood out of the heart and to the brain and other vital organs. Chest compression fraction (CCF) The percentage of time spent performing chest compressions during the resuscitation effort; an indicator of CPR quality. Chest recoil Return of the chest to the expanded position after a compression, which allows blood to flow back into the heart. Chest thrusts Inward thrusts into the chest (while pulling straight back with the thumb-side of the fist against the center of the person's breastbone) to force an object out of the airway when a person is choking.

How often do you switch roles between providers whwn giving CPR? Every 2 minutes What are the most common causes of cardiac arrest in children?
