Ammonia is generally used in household cleaning products, as well as on farms and in some industrial and commercial locations, and this makes it easy for accidental or deliberate exposure to occur. [15] [16] [17] Ammonia interacts with moist surfaces to form ammonium hydroxide, which causes necrosis of tissues. Exposure to high concentrations ...
Inhalant users inhale vapors or aerosol propellant gases using plastic bags held over the mouth or by breathing from an open container of solvents, such as gasoline or paint thinner. Nitrous oxide gases from whipped cream aerosol cans, aerosol hairspray or non-stick frying spray are sprayed into plastic bags.
The smelling salts release ammonia (NH 3) gas, which triggers an inhalation reflex. It causes the muscles that control breathing to work faster by irritating the mucous membranes of the nose and lungs. [7] Fainting can be caused by excessive parasympathetic and vagal activity that slows the heart and decreases perfusion of the brain. [14]
You can also keep your mouth open a bit while you blow, says Phillip Purnell, M.D., Ph.D., an otolaryngologist at Rutgers Robert Wood Johnson Medical School. “That helps to reduce some of the ...
Next, thrust in an inward and upward motion on the diaphragm. This will force air out of the lungs and remove the blockage. Repeat these abdominal thrusts up to five times, the doctor advised.
Smothering is a mechanical obstruction of the flow of air from the environment into the mouth or nostrils, for instance, by covering the mouth and nose with a hand, pillow, or a plastic bag. [6] Smothering can be either partial or complete, where partial indicates that the person being smothered is able to inhale some air, although less than ...
Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [1] [2] [3] This leads to hypocapnia, a reduced concentration of carbon dioxide dissolved in the blood.
Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO 2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs.
