What Does nebulization Mean
Fogging is the act and result of fogging : making a liquid turn into a kind of cloud of very small particles . It is a common medical practice for the treatment of respiratory problems.
In medicine , nebulization consists of delivering a therapeutic substance or drug in combination with a saline solution or other liquid medium. Thanks to the use of oxygen or another gas, a vapor is created that the patient must inhale.
Nebulization is often used for children with respiratory illness . This simplifies the supply of medications and the nebulization action itself helps nasal secretions become more liquid and can be removed more easily.
Although each person may have a different relationship with this method of liquid substance delivery, children generally enjoy nebulization because it relaxes them, in part because of the noise the device makes when it is in operation. In addition, if the elderly manage to avoid associating the process with medical treatment, it can even be fun, although there are serious reasons for its use.
Nebulization is also an important resource when the patient cannot use another inhalation system for mental or physical reasons; when a high dose of a drug must be given via the bronchopulmonary route; or when the drug in question is not available in a format other than liquid.
The device used to do a nebulization is called a nebulizer . This machine has a compressor, a vaporization chamber, a dosing chamber, a tube, and an inhalation pipette or mask.
The air enters the nebulizer through an opening which has a filter to prevent the passage of dust, lint and other particles. After passing through the compression chamber, the already compressed air is sent through a tube to the dosing chamber, where the therapeutic substance is shaken to generate the drops. Said drops are then drawn into the mask, which the patient must place in the airways for inhalation.
Before the invention of the electric motor, certain methods of drug delivery by inhalation already existed . For example, more than four millennia ago, in Egypt, India and China the vapors of certain plants were used to treat respiratory problems. The process consisted of preparing a mixture of herbs and heating it on a stone. One of the effects they sought through this practice was the relaxation of the musculature of the bronchi.
Already in the second half of the 19th century, spas marked the beginning of inhalation therapy as we know it today, since then nebulisations arose. In 1849, for example, the doctor Auphan built in Euzet-les-Bains, France, a room in which patients could receive steam treatments thanks to a mechanism that caused the collision of a column of water against a wall to produce an aerosol .
Two decades earlier, scientists Schneider and Waltz had created the hydroconion , a spray capable of reducing a liquid substance to a rain similar to that produced by a nebulizer. In several Swiss sanatoriums, hydroconion was used to help tuberculosis patients breathe ; For this they collected the water in the Mediterranean Sea.
In 1856, a French physician named Sales-Girons improved the hydroconion in an attempt to create a portable inhaler for use at the Perrefonds-les-Bains spa , where he set up a room with vaporized mineral water for nebulization treatments.
