Respiratory alkalosis

Definition

Respiratory alkalosis is a condition where the blood pH is elevated due to excessive loss of carbon dioxide (CO2) from rapid or deep breathing. It disrupts the acid-base balance in the body, potentially impacting pulmonary wellness.

5 Must Know Facts For Your Next Test

1. Respiratory alkalosis can result from hyperventilation caused by anxiety, fever, or high altitude.
2. Symptoms may include light-headedness, confusion, and muscle twitching.
3. It leads to decreased levels of CO2 in the blood, causing an increase in blood pH.
4. Nutrition can play a role in managing underlying conditions that contribute to respiratory alkalosis.
5. Electrolyte imbalances, particularly with potassium and calcium, are common complications of respiratory alkalosis.
