SALATI, RN, NREMT-P, CCRN, CEN, BSN +SEVERE OR COMPLETE foreign- body airway obstruction can kill the victim in minutes if he doesn’t get appropriate treatment. The pri- mary technique to clear an obstruc- tion in a conscious adult is admin- istration of abdominal thrusts—the Heimlich maneuver. In these pho- tos, you’ll learn how to help a choking victim by following the lat- est American Heart Association’s guidelines.1 (See Out with the old, in with the new for details on the latest revisions made in 2005.) Follow standard precautions for all patient contacts, but don’t delay performing the Heimlich maneuver to search for protective gear—the victim could die in even the minute 1. Ask the victim if he’s choking and if you can help him. If he nods yes and or two you spend getting gloves and can’t talk, act quickly—tell him you know what to do and you’re going to help him. a mask, and clearing a foreign body from a conscious adult’s airway shouldn’t expose you to body fluids. But if the victim becomes uncon- scious and needs rescue breathing or cardiopulmonary resuscitation (CPR), use a barrier device with a one-way valve, such as a pocket mask or shield.

The Don’ts are steps that have been replaced: • Don’t use the tongue-jaw lift to open the vic- tim’s airway. Do use the head-tilt—chin-lift maneuver. • Don’t perform a blind finger sweep of an unconscious victim’s mouth. This action hasn’t been shown effective and it could injure his mouth or your finger. Remove an object only if you see it. • Don’t perform abdominal thrusts on an unconscious victim. Studies have shown that chest compressions performed during CPR increase intrathoracic pressure as much as or more than abdominal thrusts. 5.

Following up Even when properly done, the Heimlich maneuver can injure the patient’s abdominal or thoracic vis- cera or internal organs. A health care provider should assess the victim for these complications or pulmonary aspiration. Report the event to the health care practitioner. For example, tell her you found the victim using the universal choking sign and didn’t detect air movement with respira- tory effort. You administered six abdominal thrusts, dislodging a large piece of food from the vic- tim’s airway. Now he can speak and doesn’t have any complaints.‹› REFERENCE 1. BLS for Healthcare Providers.
