Children have a cold and cough. In order to avoid running back and forth to the hospital, many parents will choose to buy child nebulizer to nebulize their children at home. However, they pay attention to the choice of household nebulizers. If the choice of nebulizers is not good, the effect will be greatly reduced. Especially the nebulizer for children, because the children's lungs are not fully developed, the nebulized drugs have higher requirements on the nebulizer if they want to reach the focus through the children's narrow respiratory tract. The effectiveness of aerosol inhalation treatment depends on the amount of drug deposition in the bronchus, and the amount of drug deposition is largely affected by the nebulizer, so children should be nebulized, and mothers should be careful to choose the nebulizer.
The size of nebulized particles is one of the main factors affecting the nebulization efficiency. The diameter of effective nebulized particles (MMAD) refers to the diameter of the nebulized particles that can be deposited in the airway and lungs with therapeutic value. It should be 0.5~10.0 um, preferably 3.0~5.0 um. However, the smaller the nebulized particles are, the better. The nebulized particles are too small to carry a limited amount of medicine and the effect of drug spray deposition is poor. Children's respiratory tract is narrow, so the nebulized particles need to be slightly smaller.
In addition to MMAD, the fog release per unit time (TOR) is also an influencing factor. TOR refers to the amount of aerosol that can be inhaled from the opening end of the nebulizer per unit time. A large amount of fog released by the nebulizer will lead to a large amount of inhaled drugs in the same time, and the drug dose will also increase, which can play a more effective therapeutic role. However, it should also be noted that the adverse reactions caused by the increase of drugs entering the body in a short time may also increase, so a comprehensive evaluation is required.
For children, the respiratory path is small, the volume of spontaneous respiration is low, the respiratory rate is high, and the amount of drug deposition in the nasal cavity is larger than that in adults. Therefore, the aerosol particles should be smaller than that in adults. Especially for some children with bronchial stenosis, it should be noted that the aerosol particles of child nebulizer are generally less than 3 microns. In addition, children often need masks for nebulization. Whether the masks are appropriate is also important. The masks should be soft and fit. The appropriate masks will not cause discomfort or allergy to children.
For example, feelife's Nebulizer specially designed for children has a median particle size of 2.5 μ m. The child nebulizer rate is 0.15-0.9/min. The invisible medicine cup can also eliminate the baby's fear. This nebulizer can also be used by newborn babies. It is equipped with a mask, made of silica gel, and has a three-dimensional structure to reduce dead space and side effects. Children can use all kinds of body positions, and it is convenient for parents to operate.
