Max air flow
The maximum air output of a compressor nebuliser during operation is a key factor to consider. It's important to note that actual performance during normal operation is often lower. Different applications have recommended air flow intensities, and knowing this parameter helps assess how well the inhaler aligns with specific recommendations.
Nebulization rate
The nebuliser's nebulization capacity per minute.
The ideal nebulization rate can differ based on factors such as the patient's health condition, the type of disease, and the composition of the inhaled medication, as outlined in medical guidelines. This rate is crucial in assessing the inhaler's effectiveness for specific situations and also influences how long the device operates on a single medication refill.
Some models have a nebulization speed control — in such cases, the maximum value is usually indicated in the characteristics.
Particle size
The aerosol generated by a nebuliser contains droplets of varying sizes. Smaller droplets have an easier time reaching the narrow passages of the bronchi, delivering the medicinal substance deeper into the respiratory system. For optimal therapeutic effects, it is recommended that droplet sizes do not surpass 5 microns. It's worth noting that during the atomization process, particles may vary in size, and their values are often expressed as a range.
Medium particle size (MMAD)
Since not all particles have the same size, this paragraph indicates exactly the average, most common particle size when splitting in this inhaler. Accordingly, lower values allow easier and deeper penetration into the bronchi.
Particle size changing
Possibility
to change the size of the particles created during the nebulization of the medicinal product. See above for size value. Here we note that high penetrating power is not always required: for some diseases (for example, inflammation in the larynx or trachea), it is not necessary to deliver the medicine deep into the bronchi. Accordingly, by changing the particle size, it is possible to control the delivery distance.
