They are by far the most frequent cause of acute asthmatic crises, in addition to the fact that allergens are persistent causes of moderate or severe asthma. Here are some examples of intra- or extra-home allergens
Viral infections produce an aggregate irritation in the respiratory tract, nose, throat, lungs and sinuses. This irritation frequently precedes and triggers asthma attacks. The exact biological mechanism of this process is not known.
Smoke from wood-burning heaters and fireplaces can be extremely irritating to asthmatics because of the release of chemicals such as sulfur dioxide. Good ventilation should be maintained if heaters and fireplaces are used, but if possible it is best to avoid them.
Exercise can also trigger an asthmatic attack. It is estimated that 85% of allergic asthmatics have bronchospasm (wheezing) symptoms after exercise. Inhalation of cold, dry air during exercise appears to be a strong asthma trigger.

A. LIVID CHIMNEYS: All chimneys used to evacuate gases and combustion products coming from domestic appliances working at relatively low temperatures, such as light bulbs, kitchen stoves, low pressure boilers, garbage incinerators, heaters, etc., shall be considered of this type. These chimneys shall be constructed in masonry or reinforced concrete and their walls shall have a minimum of zero point ten meters (0.10m), previously lined in heat resistant brick with metallic pipes, shall have a height of not less than zero point sixty meters (0.60m) higher than any roof located within a radius of three meters (3m) around them. B. MEDIUM OR SEMI-HEAVY CHIMNEYS: All chimneys used for the removal of products used for the removal of products of combustion, or riginated by industrial apparatus operating at medium temperatures, such as high pressure boilers, certain types of incinerators, etc., shall be considered within this type. These chimneys shall be built with masonry or reinforced concrete walls with a minimum thickness of zero point twenty-five (0.25m) and shall have an interior lining of clay or refractory brick, and shall have a height of not less than two meters (2m) higher than the entire roof within a radius of ten meters (10m) around it.
Coughing is a defense mechanism that aims to expel mucus from the respiratory tract in order to keep it clean and clear. It is therefore a “protective reflex” of the body, and one of the most frequent causes in pediatric consultations.
To diagnose the reason for the cough, the physician analyzes what it is like, what characteristics it presents, how it sounds, in what situations it occurs and when it started. All this, together with the patient’s physical examination and medical history, will indicate the disease or pathology present.
There are different types of washbasins. This is where determining aspects come into play, such as the distribution, the aesthetics of the product to be purchased, the location of the water inlets, among others.
Built-in washbasins are those that are fitted into the countertop. For this, it will be necessary to take into account the available space as well as the upper perimeter edge of the washbasin that, generally, will be slightly above the level of the countertop.
The material of which the washbasin is made is one of the most important aspects to highlight since it determines, mainly, the style and also the ease of maintenance and care that must be taken during its use. There are different types:
It is a compact, hard and scratch resistant material. It stands out for its durability and high gloss and has great maintenance advantages, such as ease of cleaning (resistant to any cleaning product).
