Under my guidance, I have seen many children who have greatly reduced the number of infusions (some have gotten better without infusions at all) because they have cooperated with nebulizer therapy. Having the trust of parents and seeing the rapid improvement of their children made me feel the value of living. Many parents ask me what kind of nebulizer they should buy. At present, there are many kinds of nebulizer machines, many domestic and imported brands, and there are many different kinds of nebulizers and after-sales services. You can compare it with your own eyes. In general, the nebulizer is divided into two kinds of compression nebulization and ultrasonic nebulization. (Reference network knowledge, there is not right, please propose.) Their common points: first of all, the purpose of compressed air nebulizer and ultrasonic nebulizer is the same, are anti-inflammatory, cough suppression, expectorant, release bronchospasm, is a smooth airway, improve ventilation function, before and after chest surgery, in order to prevent respiratory tract infection, with artificial respiration to make the airway wet or intermittent inhalation of drugs, etc.. Differences: 1, the working principle is different: compressed nebulizer: is the use of the compressor through the antibacterial network of cotton-based filtered clean air compressed into a strong airflow, sprayed by the jet, impacting the liquid in the medicine cup, the liquid will be vaporized, and then sprayed out by the fog mouth for oral and nasal inhalation, due to the drug particles fine, atomized into between 1-5 microns in diameter, easy to breathe through the deep into the lungs, bronchial vascular parts It is suitable for direct absorption by human body, improve the efficacy and speed up the therapeutic effect, and has a long service life. Ultrasonic nebulizer: is from the independent circuit board oscillation signal through the high-power transistor for energy amplification, and then passed to the ultrasonic chip, ultrasonic chip and then the electrical energy into ultrasonic energy, ultrasonic energy at room temperature can atomize water-soluble drugs into 5-8 microns of particles, with water as the medium, the use of ultrasound directional pressure of water-soluble drugs sprayed into a mist, with the internal fan wind will be sprayed into the patient’s airway and then absorbed by the patient. 2, the effect is different ultrasonic nebulizer: ultrasonic nebulizer sprayer on the fog particles without selective with, so most of the drug particles produced can only be deposited in the oral cavity, throat and other upper respiratory tract, and because the amount of deposition in the lungs is very small, can not effectively treat lower respiratory tract diseases. At the same time, because the ultrasonic nebulizer produces large fog particles, fast atomization, resulting in patients inhaling too much water vapor, making the respiratory tract wet, the respiratory tract was partly blocked bronchial dry thick secretions absorb water and swell, increasing the resistance of the respiratory tract, may produce hypoxia, and ultrasonic nebulizer will make the drug crystallized into water droplets hanging on the wall of the inner cavity, the effect on the lower respiratory tract diseases is not good, the demand for drugs is large, and Causes the phenomenon of waste. Compressed nebulizer: due to the fine drug particles, nebulized into a diameter of 1-5 microns, easy to breathe deep into the lungs, bronchial vascular parts, and less drug, suitable for direct absorption of the body, improve the efficacy, accelerate the effectiveness of treatment, long service life. 3, the use of different groups of people compression nebulizer: adults and children can use, for patients of all ages, is the ideal appliance for families and medical units. Please note that parents buy, a price is worth every penny, the cheap price is not necessarily the best. Ultrasonic nebulizer: only for adults. There are reports that in view of the ultrasonic nebulizer in the treatment effect, service life, operation cleaning and other reasons, foreign developed countries have ultrasonic nebulizer completely eliminated from the market. The domestic market due to expensive general public is not willing to spend a lot of money to buy, so the compression nebulizer in the domestic is not yet recognized and accepted by ordinary families, but hospitals have been slowly replacing the ultrasonic nebulizer with compression nebulizer. Finally, we remind you that different diseases need to choose different drugs for nebulization treatment, and what drugs to use, need to be used under the guidance of doctors, do not configure their own private. Acute asthma attack, if the lack of oxygen is very obvious, such as the child has obvious breathing difficulties, must be hospitalized, with infusion treatment, so, not all cases are suitable for nebulization at home itself, there is a lack of oxygen, need to go to the hospital under the oxygen-driven nebulization.
