add example. 1  en The Amur Leopard (from the name of the river flowing at the border between Russia and China, or Far Eastern leopard, Panthera pardus orientalis) is quite certainly the rarest and most endangered big cat in the world because of a wild population of only 30 to 35 individuals [ 1 ].
Rebreathing resulted in acidosis because the pH value began to dip below the normal range between 20 and 30 secods--as soon as it went below 7.35. Acidosis is the result of impaired respiration (hypoventilation)that leads to the accumulation of too much carbon dioxide in the blood.
The production and removal of CO 2 and H + , together with the use and transport of O 2, cause chemical changes in the blood. These chemical changes, unless offset by other physiological functions, cause the pH of the blood to drop. If the pH of the body gets too low (below 7.4), a condition known as acidosis results. This can be very serious, because many of the chemical reactions that occur in the body, especially those involving proteins, are pH-dependent. Ideally, the pH of the blood should be maintained at 7.4.
