The wavelike motions of the cilia move the macrophages which contain dust to the throat, where they are spat out or swallowed.īesides macrophages, the lungs have another system for the removal of dust. Then the macrophages, in a way which is not well understood, reach the part of the airways that is covered by cilia. Macrophages virtually swallow the particles. These are extremely important for the defense of the lungs.
The air sacs are very important because through them, the body receives oxygen and releases carbon dioxide.ĭust that reaches the sacs and the lower part of the airways where there are no cilia is attacked by special cells called macrophages. The air reaches the tiny air sacs (alveoli) in the inner part of the lungs with any dust particles that avoided the defenses in the nose and airways. Tiny hairs called cilia, covering the walls of the air tubes, move the mucus upward and out into the throat, where it is either coughed up and spat out, or swallowed. The mucus they produce catches most of the dust particles. These tubes are called bronchi and bronchioles. Some of the smaller particles succeed in passing through the nose to reach the windpipe and the dividing air tubes that lead to the lungs. Most large particles are stopped in it, until they are removed mechanically by blowing the nose or sneezing. When a person breathes in, particles suspended in the air enter the nose, but not all of them reach the lungs.

“The best thing is to stay aware as you’re eating, and know what you would do in an emergency situation.The lungs are protected by a series of defense mechanisms in different regions of the respiratory tract. “You could choke on a lozenge,” he notes. Keep in mind, too, that it’s not just big chunks of meat that can be a problem. Also, the muscles in your throat aren’t as coordinated as when you’re sober, says Dr. That’s because drinking changes your perception of when food is adequately chewed, so you tend to swallow sooner. “Many times when there’s choking, alcohol is involved,” he says. Bradley suggests limiting alcohol consumption.
In addition to taking smaller bites and chewing more thoroughly, Dr. Of course, not choking at all is the best remedy. The type of hard thrusts necessary to expel food can do a number on your abdomen and organs, so you might be facing a ruptured spleen or other issues.Īlso, there’s a chance some of the food could have gone into your lungs, which might cause inflammation, collapse or infection. If you do get that food chunk out-congrats on saving your own life-then it’s still a good idea to go to the emergency room, Dr.
In some areas, they have the technology to do this for cell phone calls as well. At this point, you’ve likely lost quite a bit of air and even though you can’t speak, and may pass out soon, emergency responders can help.Įmergency services will automatically send help to any call, even if no one is talking on the other end. If five or six quick thrusts isn’t doing the job, call 911 immediately, preferably from a landline. This provides a hard pressure wave designed to drive air upward, providing enough force to propel the food out of its stuck position, Dr. If that’s not working, keep your hands in the same position and lean quickly over the back of a sturdy chair to exert more force into the push.

A class will be particularly helpful for learning how to assist others-for example, the Red Cross recommends back blows first when someone else is choking, and then follow with abdominal thrusts. That’s the basics of it, but if the motion makes you nervous consider signing up for a Red Cross class to get the first aid procedure down. This will exert pressure on the bottom of the diaphragm, which compresses the lungs and forces the remaining air to push up through the trachea-hopefully with enough pressure to dislodge the food. Push as hard as you can in a quick motion straight into the area. Then place your other hand on top of that. Make a fist with one hand and put the thumb side between your belly button and rib cage, Dr. Yes, it’s the same action you’d use to help someone else choke, but you’d be doing it on yourself. Try to cough as forcefully as possible, like you do when you’re trying to hack up mucus when you’re sick.ĭon’t drink any water to try forcing the food down-that can actually make it worse, Dr. If you can cough or make any sound, that’s good news: Your airway isn’t completely blocked off, so you have a shot at coughing it out. Follow these steps to save yourself from choking when you’re all alone.
Irreversible brain death occurs in about 10 minutes.īut try to keep calm and act fast-your life depends on it. But if you don’t get the obstruction-the food-removed within four to six minutes, your brain can start to suffer serious damage. Oxygen stored in the lungs can keep you alive for several minutes if your breathing is blocked.
