How do we breathe?
We breathe in and out over 20,000 times a day. When inhaling, the chest rises and the diaphragm expands downward, creating a partial vacuum in the chest. This vacuum draws the inhaled air into the upper and lower respiratory passages. When exhaling, the lungs and chest return to their initial position and the spent air is expelled from the body via the respiratory passages. Respiration is accurately adjusted to the current metabolic condition – for example, physical rest or activity – by the so-called respiratory centre of the brain.
Every one who suffers of diferent type of alergies, problem with sinuses and bronchi know very well how many problems they have in difernet period of year. So we must always be ready to help yourself, our children and loved ones with whom we live. Modern Citizen inhalators just serve to help in this situation.
