What are 2 conditions in which hyperventilation may occur?

Hyperventilation may occur in conditions such as anxiety or panic attacks, where rapid, shallow breathing is often a response to heightened stress or fear. It can also happen during vigorous physical exercise, as the body demands more oxygen and attempts to expel carbon dioxide more quickly. Additionally, certain medical conditions like Asthma or pulmonary embolism can lead to hyperventilation as the body struggles to obtain adequate oxygen.
