With eye pain, there may be other symptoms too, which may help diagnose the cause of the discomfort. These include: 1  Conjunctivitis-red itchy eyes. 2  Tears. 3  Light sensitivity (photophobia). 4  Discharge, which can be clear, or thick and coloured (pus). 5  The eye being crusted shut after sleep due to discharge.
The process of breathing performs a number of important gas exchanges through inhalation and exhalation. When someone inhales, they contract and move their diaphragm, which allows the lungs to expand. This is a part of the process needed to psychically suck in the air. When a person exhales, the diaphragm relaxes and the movement is undone. This allows air to be gradually pushed out of the lungs.
Hyperventilation occurs when the rate and quantity of alveolar ventilation of carbon dioxide exceeds the body's production of carbon dioxide. Hyperventilation can be voluntary or involuntary. When alveolar ventilation is excessive, more carbon dioxide will be removed from the blood stream than the body can produce.This causes the concentration of carbon dioxide in the blood stream to fall and produces a state known as hypocapnia. The body normally attempts to compensate for this metabolically.hen hyperventilation leads to respiratory alkalosis, it may cause a number of physical symptoms: dizziness, tingling in the lips, hands or feet, headache, weakness, fainting and seizures.
