Which type of hyperventilation is often associated with severe anxiety or panic attacks?

Psychogenic hyperventilation is characterized by an increase in ventilation that occurs in response to psychological factors, particularly during episodes of severe anxiety or panic attacks. In these situations, individuals may experience rapid and deep breathing as a physiological response to stress or fear, which often leads to a reduction in carbon dioxide levels in the blood. This can cause symptoms like lightheadedness, tingling in the extremities, and a feeling of breathlessness, which can further exacerbate the panic or anxiety.

In contrast, obstructive hyperventilation is related to conditions that obstruct airflow, while respiratory acidosis due to hypoventilation is associated with insufficient ventilation that leads to increased carbon dioxide levels in the blood. Legal hyperventilation is not a recognized medical term or condition related to respiratory physiology. Hence, understanding psychogenic hyperventilation is crucial as it highlights the interplay between psychological states and physiological responses in respiratory care.
