A Nebulizer is an instrument that converts liquids into micrometer sized droplets, making it appear hazy at a macroscopic level. According to different uses, centrifugal atomizers can be mainly divided into air humidifiers and medical atomizers, also known as atomizers or atomizers. Air humidifiers are used to improve the relative humidity of indoor air, while medical atomizers are mainly used to treat upper and lower respiratory system diseases.
The atomization force and quality of centrifugal atomizers will directly affect the effect, and regular brands should be selected, and unqualified atomizers should not be used. In addition, there are many types of drugs used to treat the respiratory tract, and each child's condition is different. The dosage, time, and frequency of medication also vary. Doctors will adjust medication according to personal and medical conditions at any time, so even if nebulization is done at home, it is necessary to go to the hospital for regular check ups. Doctors remind that general nebulized drugs have both fat solubility and water solubility, and all nebulized drugs must be used strictly according to the instructions. If the drug instructions do not indicate that nebulization is allowed, it is not recommended for parents to use. At the same time, the effectiveness of high-pressure saline atomization is controversial. Experts believe that high osmotic saline atomization may cause adverse reactions such as airway hyperresponsiveness and airway spasms, and it is not recommended for parents to use. To avoid side effects, parents should not take medication without authorization.
Precautions for purchasing a centrifugal atomizer: 1. Noise: The noise level of the atomizer is an important indicator of its quality, and high noise can affect the patient's negative emotions. The noise level of most compressed atomizers sold on the market is around 80 decibels, while a good compressed atomizer should have a noise level of less than 65 decibels. Machines with loud noise can generally be felt, and manufacturers do not label the noise level of the machine. 2. Vibration: Noise accompanied by vibration. Generally speaking, when there is a lot of noise, the vibration is definitely not small. 3. Heating: Along with the noise and vibration above, it is a problem of heating. Machines with high noise and vibration will inevitably generate more heat. So the nominal power of the compressed atomizer is not necessarily better, as most of the energy of machines with high power but high noise is wasted. 4. Atomized particles: The size of atomized particles directly affects the atomization effect, and smaller atomized particles can reach the lower respiratory tract and alveoli. The specifications provided by general manufacturers include labels indicating the size of atomized particles, which generally refer to particle size, mean particle size (MMAD), mean median particle size (MMD), etc. The size of atomized particles is influenced by two factors: the compressor and atomization cup. The compressor provides constant pressure air, and the process of atomizing the cup determines the size of the excited particles.
Precautions for using centrifugal atomizers: 1. The inhalation time of air compressed atomizers should not exceed 20 minutes each time, and the inhalation time is not proportional to the therapeutic effect; 2. Disinfect the nebulizer cup, mask, and mouthpiece before use; 3. Choose a quiet and clean operating environment and use with caution in flammable environments. The atomizer should be placed on a flat tabletop, not on tilted areas such as legs or beds; 4. After each use, clean the items used and dry them in a cool and ventilated place.
