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.
respiratory alkalosis: hyper ventilation, rapid rate of breathing, causes too much carbon dioxide to be exhaled and the ph of the body rises. the cardinal sign of respiratory alkalosis is the deep, rapid breathing, more than 40 breaths per minute, that is similar to kussmaul's respirations (seen in metabolic acidosis).
