The doctor will rapidly examine the patient, especially breathing and circulation. If the doctor does not find anything immediately life-threatening, the doctor will ask about medical history and do a physical exam.

Certain tests may be ordered to explore other causes of the patient's signs and symptoms. These tests are often ordered because the only way to confirm a person has hyperventilation syndrome is to eliminate other causes. The patient may have an IV started and may be hooked up to a monitor during the evaluation. The doctor may order these tests:

• Arterial blood sample
• Other blood tests
• Chest X-ray
• Ventilation/perfusion scan
• Chest CT scan
• Electrocardiogram (ECG, EKG)

If the doctor suspects the patient may have a condition more serious than hyperventilation syndrome, the doctor may recommend that hospitalization for further tests and observation. Life-threatening conditions associated with rapid or deep breathing include:

• Heart problems
• Lung problems
• Nervous system problems
• Drug reactions and poisons
• Infection
• Pregnancy
• Liver disorders
