Under normal conditions, hyperventilation will eventually lead to unconsciousness because Group of answer choices blood pH drops
Dmitry [639]

Answer:

The correct answer is ''it leads to respiratory alkalosis.''

Explanation:

Respiratory alkalosis is defined by pH values> 7.45, and is characterized by an increase in pH and a decrease in pCO2. The most frequent cause is alveolar hyperventilation. Alveolar hyperventilation causes respiratory alkalosis, presenting a decrease in ionic calcium and in some cases tetany. To compensate for this increase in pH, renal HCO3 excretion is increased, but this process requires 24-48 hours. Respiratory alkalosis - primary or compensatory - is defined by hypocapnia, a finding that involves alveolar hypoventilation. The symptoms of acute respiratory alkalosis, the "hyperventilation syndrome," vary only in intensity from those of any alkalosis - most notably disturbances in neuromuscular function (eg, paresthesias, tetany, tremor). A constellation of symptoms have been described with respiratory alkalosis, including increased intracranial pressure, decreased consciousness, tachycardia, hypertension, carpopedal spasm, anxiety, dizziness, and a feeling of vertigo.

3. They are isolated so they do not socialize with other tigers, unless they are hungry.
