10.12 Hyperventilation

10.12.2 Define hyperventilation.

Hyperventilation, often known as "over breathing", is when someone breathes too rapidly and deeply, often more than the body needs.

The body then experiences a shift in the normal balance of carbon dioxide and oxygen and leads to a decrease in carbon dioxide levels in your blood.

10.12.4 Explain the causes of hyperventilation.

Hyperventilation can be triggered by various factors, such as:

• anxiety or panic attacks
• stress,
• fear,
• pain, 
• emotional distress, or
• hypoxia.

Additionally, certain medical conditions like asthma, respiratory infections, or metabolic disorders can contribute to hyperventilation.

10.12.6 Describe the symptoms of hyperventilation.

When someone is experiencing hyperventilation, they may exhibit a range of symptoms.

These can include:

• rapid breathing,
• shortness of breath,
• feeling lightheaded or dizzy,
• tingling or numbness in the hands or feet,
• chest tightness, and
• a sensation of not getting enough air.

Some people may also experience palpitations, a dry mouth, or feelings of anxiety or panic.

10.12.8 Describe how hyperventilation can be treated.

To treat hyperventilation, it's important to focus on restoring a balanced breathing pattern.
