Therefore, bird species, including the common raven, seem to be in an acute state of respiratory alkalosis relative to mammals.
12.
Gradually, the body compensates for the respiratory alkalosis by renal excretion of bicarbonate, allowing adequate respiration to provide oxygen without risking alkalosis.
13.
On the other hand, respiratory alkalosis ( Pa CO 2 < 35mmHg ) occurs when there is too little carbon dioxide in the blood.
14.
Breathing that is too slow or shallow causes respiratory acidosis, while breathing that is too rapid leads to hyperventilation, which can cause respiratory alkalosis.
15.
Four fundamental changes may occur that affect acid-base balance in the body : respiratory acidosis, respiratory alkalosis, metabolic acidosis and metabolic alkalosis.
16.
If excess ventilation cannot be compensated metabolically, it will lead to a rise in blood pH . This rise in blood pH is known as respiratory alkalosis.
17.
The hyperventilation is self-promulgating as rapid breathing causes carbon dioxide levels to fall below healthy levels, and respiratory alkalosis ( high blood pH ) develops.
18.
The respiratory alkalosis leads to changes in the way the nervous system fires and leads to the paresthesia, dizziness, and perceptual changes that often accompany this condition.
19.
When 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.
20.
When faced with a heat load, birds often use thermal panting and this adaptation of tracheal coiling allows ventilation of non-exchange surfaces which can enable the bird to avoid respiratory alkalosis.
