What is hyperventilation?

Hyperventilation is characterized by rapid or deep breathing, which can significantly reduce carbon dioxide levels in the blood. When a person hyperventilates, they exhale CO2 faster than the body produces it, leading to a decrease in carbon dioxide levels (hypocapnia) and causing a range of physiological effects. This condition often results in symptoms such as lightheadedness, tingling in the extremities, and potentially even syncope (fainting). Understanding this process is crucial for healthcare providers, as it can result from various triggers, including anxiety, panic attacks, or medical conditions, and requires appropriate management and intervention.
