【单选题】The one accident situation where immediate action must be taken is when a person stops breathing. This might be the result of drowning, electrocution, suffocation, head injury caused by a fall, poisoning or a variety of other accidents.
If someone has stopped breathing, however, there may be a simpler cause—the breathing passages may be blocked by food, vomit, saliva or even the tongue...
Whatever the cause, it is imperative that breathing is restarted quickly, as otherwise brain damage may result.Act quickly: lay the casualty flat on his back, and pull back the head while holding the jaws clencheD、This prevents the tongue from falling back into the throat and blocking the air passages. If any foreign matter like sand or vomit can be seen in the victim’s mouth or throat, scoop it out with the fingers. False teeth are a particular hazard and often fall back into the throat of an unconscious person.
If breathing does not start immediately, you must begin artificial respiration right away, by breathing directly into the casualty’s lungs through the mouth or nose...As you exhale deeply through the casualty’s nose, it is necessary to hold their mouth firmly closeD、If you are breathing into the mouth, however, pinch the nostrils to stop the escape of air. If the airways are not obstructed you will see the chest of the casualty’s lungs.Each time you blow, turn your head to check that there is regular rise and fall of the chest. This must be continued until breathing starts spontaneously, or in any event for at least an hour.As soon as the casualty starts to respond you should see an improvement in his colour, usually after the first dozen or so inflations. When breathing starts, it will be weak and shallow, and will still need assisting. Time your breaths to coincide with those of the casualty, as his breathing gradually strengthens.
When breathing has restarted and can continue without help, the casualty will still be unconscious. He should be turned into the "unconscious’’ position, preferably with the body slightly higher than the head, and watched carefully to make sure that breathing continues.Don’t rush to get him to hospital. It is more important to make sure that breathing is strong and will continue while the casualty is being moveD、
When applying artificial respiration it is important to keep a careful eye on ______.
A、your rate of breathing
B、signs of unconsciousness
C、the casualty’s chest
D、any reaction to colour
