Occasionally choked by dust inside the trachea, do not be overly nervous, this time quickly drink more hot water, or inhale some hot steam, and then help it out. Because the lungs actually have a very strong self-protection ability, the lungs inside the airway mucosa and alveolar surface mucosa are protected by mucus, these mucus is always ready to standby, as long as the outside comes in some dirty things, in fact, not only dust, including some pathogens, there are other allergens, can be wrapped up through the lungs inside the mucus, from the airway to send out is often said to drain sputum. If you choke on dust, you can make full use of the lung’s ability to expel phlegm to help it out as much as possible, on the one hand, to add water to the airway, is to do some nebulization, drink more water; on the other hand, if you feel more inhaled, you can also increase some phlegm medicine. It is not enough to use these, but should also increase the breathing action, the greater the breathing action, the faster these garbage will be expelled.
