Background on inhalation

How our lungs clean themselves and what scavenger cells are

Our airways have a very good filter – the self-cleaning mechanism: Large particles of dirt get stuck in the nose and are blown out. All our airways have mucous membranes and fine hairs called cilia. In healthy people, foreign bodies like viruses and bacteria stick to the mucous membranes. The beating motion of the cilia transports foreign bodies towards the throat. If the foreign bodies are very small and reach the smallest branches of the lungs, the alveoli, the lungs are cleaned with the aid of macrophages. Macrophages are part of our immune system and are also called scavenger cells or phagocytes. Foreign bodies and pathogens are detected, engulfed, broken down by enzymes and rendered harmless.
 

What happens if the cleaning mechanism is impaired

In the winter, for example, when central heating is turned up full blast, the mucous membranes can dry out. This impairs the natural self-cleaning mechanism of our airways. If the protective moisture film is missing, we can catch a cold because viruses and bacteria can more easily reach the mucosal cells. This is why it is advisable to perform inhalation with an isotonic saline solution to prevent colds. This re-moistens the airways, helping to remove pathogens; this can also have a positive impact during pollen season. But too much mucus is also a problem. The fine hairs then cannot as effectively remove viruses and bacteria. In this case, the inhalation of hypertonic saline solutions can help to liquefy the mucus. This also supports your natural cleaning mechanism. 
 

Aerosol – soothing fine mist from the inhalation device

To allow the isotonic or hypertonic saline solution or medication mixture to have the desired effect, the PARI nebuliser, in combination with the inhalation device, produces very fine droplets. This aerosol, as it is called, is directly absorbed via the mucous membranes. Whether the aerosol acts in the nose, the sinuses or the lungs depends on, among other factors, its size. Larger droplets, such as those produced by the PARI LC SPINRT XLent, only get to the upper airways, the mouth or throat, the larynx or the nasal region. Smaller and finer droplets on the other hand, such as those produced by the nebuliser for the PARI BOY Junior , can get deep into your lungs.
 

What the colours of the nebuliser inserts mean

The nebuliser is what actually generates the aerosol, so it is the most vital component of the entire inhalation system. To ensure that the aerosol has the optimum effect at a certain site, such as the sinuses or the lungs, a specific aerosol has to be generated. The nebulisers from the PARI LC SPRINT family are fitted with nozzle attachments in a range of colours. Each colour generates a different droplet size adjusted to the age group or the clinical condition. 

The following nozzle attachments are available:
