Final answer:
Respiratory alkalosis is an increase in the rate and depth of respiration, causing excess exhalation of carbon dioxide and alkalosis. It is often associated with hyperventilation and can be caused by various factors such as emotional upset or fever.
Step-by-step explanation:
Respiratory alkalosis is an increase in the rate and depth of respiration, causing an excess exhalation of carbon dioxide and alkalosis. This condition usually occurs when too much carbon dioxide is exhaled from the lungs, as in hyperventilation. It can be caused by emotional upset, fever, hypoxia, or high levels of catecholamines.
