Basic life support is maintenance of the ABCs (airway, breathing, and circulation) without auxiliary equipment. The primary importance is placed on establishing and maintaining an adequate open airway. Airway obstruction alone may be the emergency: a shipmate begins choking on a piece of food. Restore breathing to reverse respiratory arrest (stopped breathing) commonly caused by electric shock, drowning, head injuries, and allergic reactions. Restore circulation to keep blood circulating and carrying oxygen to the heart, lungs, brain, and body.
Airway obstruction, also known as choking, occurs when the airway (route for passage of air into and out of the lungs) becomes blocked. The restoration of breathing takes precedence over all other measures. The reason for this is simple: If a casualty cannot breathe, he or she cannot live. Individuals who are choking may stop breathing and become unconscious. The universally recognized distress signal for choking is the casualty clutching at his or her throat with one or both hands. The most common causes of airway obstruction are swallowing large pieces of improperly chewed food, drinking alcohol before or during meals, and laughing while eating. The tongue is the most common cause of obstruction in the casualty who is unconscious. A foreign body can cause a partial or complete airway obstruction. Partial Airway Obstruction
If the casualty can cough forcefully, and is able to speak, there is good air exchange. Encourage him or her to continue coughing in an attempt to dislodge the object. Do not interfere with the casualty's efforts to remove the obstruction. First aid for a partial airway obstruction is limited to encouragement and observation. When good air exchange progresses to poor air exchange, demonstrated by a weak or ineffective cough, a high-pitched noise when inhaling, and a bluish discoloration (cyanosis) of the skin (around the finger nails and lips), treat as a complete airway obstruction. Complete Airway Obstruction
A complete airway obstruction presents with a completely blocked airway, and an inability to speak, cough, or breathe. If the casualty is conscious, he or she may display the universal distress signal. Ask "Are YOU choking?" If the casualty is choking, do the following:
1. Shout "Help"-Ask the casualty if you can help.
2. Request medical assistance - Say "Airway is obstructed" (blocked), call (Local emergency number or medical.

d. Grasp your fist with your other hand.
e. Keeping your elbows out, press your fist (Fig. 2-3) into the abdomen with a quick upward thrust.
f. Repeat until the obstruction is clear or the casualty becomes unconscious.
