About hyperventilation syndrome

Hyperventilation syndrome is an episode that occurs in the emergency department. This phenomenon is easily recognized by many doctors. But at the same time, the underlying pathophysiological side has not been clearly explained.

As a rule, it is defined as a condition in which minute ventilation exceeds the requirements of metabolism, which leads to hemodynamic and chemical changes that produce the characteristic symptoms of some syndromes. Inducing a decrease in arterial partial pressure of carbon dioxide (RaSO2) through voluntary hyperventilation reproduces these symptoms.

However, this model has been challenged by the observation that many hyperventilated patients do not exhibit low PaCE2 during seizures. In some cases, a change in respiratory physiology has been observed in patients with this syndrome, which manifests itself in a slower return of RaSO2 to baseline levels after voluntary hyperventilation to a certain level of RaSO2.

Current consideration suggests that a better term for this syndrome may be behavioral dyspnea or psychogenic dyspnea. And hyperventilation is considered as a consequence, not the cause of the disease. In addition, it has been revealed that some patients may be physiologically at risk of developing psychogenic dyspnea.

The symptoms of hyperventilation and panic disorder overlap to a large extent, although the two conditions remain distinct. Approximately 50% of patients with panic disorder and 60% of patients with agoraphobia have hyperventilation as a symptom, while 25% of patients with hyperventilation have panic disorder.

After the first bout of acute hyperventilation, diagnosis depends on recognizing typical signs and symptoms, and excluding serious conditions that may cause existing symptoms. A low pulse oximetry reading in a patient should never be attributed to hyperventilation. These patients should always be evaluated for other reasons of hyperventilation.

Provoking symptoms if the patient has voluntary hyperventilation for 3-4 minutes is often time-consuming and may be ineffective. Diaphragmatic breathing slows down the breathing rate, gives patients distracting time to complete the process when attacks occur, and provides safety for patients with a sense of self-control during episodes of hyperventilation.
