Hyperventilation causes too much oxygen to be taken in and carbon dioxide to be discarded too quickly, which causes fainting, as explained by WebMD. Acute hyperventilation is often triggered by anxiety or a specific phobia. Acute decreases in carbon dioxide can lower cerebral blood flow and cause neurologic symptoms such as syncope, seizure, dizziness and confusion.Know More
WebMD recommends breathing into a paper bag in the event of hyperventilation, a home remedy which supplies an old but still applicable solution. Breathing into a paper bag forces inhalation of carbon dioxide, which slows the rate of breathing as well as regulating the acid-base balance so that the individual does not faint or enter respiratory alkalosis. Web MD also recommends diaphragmatic breathing, pinching one nostril shut, and breathing through pursed lips as other strategies to treat hyperventilation before a person reaches the point of syncope.
According to Medscape, hyperventilation can lead to syncope and in extreme cases, respiratory alkalosis. In a healthy human the acid-base balance remains relatively stable. Normal processes malfunction when pH levels climb too high (alkalosis) or drop too low (acidosis). Hyperventilation causes a loss of carbon dioxide which drives up pH levels. Hyperventilation syndrome, or acute respiratory alkalosis, is characterized by paresthesias, tingling and numbness around the mouth, chest tightness or pain, difficult breathing, and tetany.Learn more about Conditions & Diseases
A stomata is the part of a plant that allows gases such as oxygen and carbon dioxide to move freely into and out of a leaf. Every plant with above-ground leaves has stomata.Full Answer >
According to Estrella Mountain Community College, people need to breathe because human cells require oxygen to use food energy efficiently and to release the carbon dioxide generated by that use. The lungs are designed to maximize their surface area as they fill with air in order to allow as much of the gases to diffuse into and out of the blood as possible.Full Answer >
Plants take in carbon dioxide and expel oxygen through photosynthesis, while animals breathe in oxygen and expel the carbon dioxide. Known as the oxygen cycle, this mirrored use of carbon dioxide and oxygen does have a few exceptions.Full Answer >
The air exhaled from the lungs has a lower oxygen content and higher carbon dioxide content than normal air, leading to an increase in the respiratory rate. Receptors in the arteries detect the partial pressure of oxygen and carbon dioxide in the bloodstream and increase or decrease the respiratory rate to establish balance, according to an article in The Medical Journal of Australia.Full Answer >
