What is Affecting Nebulizing Effect
As we all know, aerosol inhalation therapy is an efficient and convenient therapy for respiratory diseases. In recent years, it has also been continuously innovated and improved in medicine output and inhalation efficiency. However, why sometimes nebulizing effect is differ from time to time? How to distinguish the quality of treatment? Let's uncover the mystery of nebulization treatment efficiency and talk about factors that affecting treatment.
First, it’s nebulized particle size. Studies have shown that particles with a diameter of 1-5μm have more sedimentation in the lower airways and lungs. Among them, 1-3μm particles have the most ideal settlement in the bronchioles and alveoli, while 5-10μm particles are mostly settle in the upper air. Particles larger than 10-15μm almost all settle in mouth. However, particles smaller than 1μm are suspended in the air after being sucked into the lungs, but the amount of settlement is small, and most of them are exhaled with the exhalation airflow. Therefore, 1--5μm particle size is the optimal range. When choosing a nebulizer, keep an eye on particle size that produced by the nebulizer.
Second, it’s the nebulize speed and the way you breathe. If nebulization speed is too low, enough liquid medicine cannot be inhaled, resulting in insignificant therapeutic effects. Meanwhile, if you deliberately breathe hard during nebulizing treatment, it will cause the inhalation flow to be too fast, which will promote aerosols to collide with each other and deposit in the mouth, pharynx and large airways, and cannot reach the affected area. Also hard breathing will worse your poor lung function, make the inhaled medicine be exhaled before it gets deep enough. So, you just need to breathe normally with a proper nebulize speed during treatment.
Third, the medicine for nebulizing treatment is also very important. Too little liquid medicine, the amount of them reaching the lower respiratory tract is relatively small, therapeutic effect cannot be achieved. Excessive amount of medicine leads to too long nebulizing time, which also affects the quality and drug properties of the mist. Generally speaking, one nebulization of 4~6ml for adults, 3~4ml for children is enough. Besides, use a single-dose medicine as much as possible to avoid the risk of contamination. When multiple medicine are compatible, pay special attention to the incompatibility and stability of the drugs. Last but not least, please use nebulized medicine under the guidance of a doctor and do not use medicine on your own.
The last one is always keep the nebulizer clean and hygienic, and clean it before and after use. If use a mesh nebulizer, you should replace the liquid medication cup and nebulization piece regularly to avoid contamination.
In addition to the above factors, in order to avoid recurrence or aggravation of the disease, patients should pay more attention to nursing at ordinary times, which will greatly help the improvement of the disease.
