What Is Hyperoxemia

Hyperoxemia can be defined as an increase in arterial oxygen partial pressure (PaO2) to a level greater than 120 mmHg (16 kPa) and may occur in up to 50% of mechanically ventilated patients.

Why is Hyperoxemia bad?

But it is important to realize that hyperoxemia is associated with increased mortality and unfavorable outcome, such as more neurological impairment and Acute Respiratory Distress Syndrome (ARDS).

What causes Hyperoxemia?

Hyperoxia occurs when cells, tissues and organs are exposed to an excess supply of oxygen (O2) or higher than normal partial pressure of oxygen.
