2. O xygenation  is the process of supplying oxygen to the body’s cells.  Ventilation  is the process of exchanging oxygen and carbon dioxide, which is essentially breathing. Perfusion is the body process of supplying oxygenated blood to the cells and is reliant on adequate cardiac output in order to be optimal . Hypoxia and hypoxemia Two other terms that you need to know as you are learning about oxygenation are  hypoxia  and  hypoxemia . A lot of times you will hear these terms used interchangeably, though hypoxia refers to a low oxygen level in the tissues, whereas hypoxemia is low oxygen level in arterial blood. Hypoxia is a SpO2 < 90% as measured by pulse oximetry and hypoxemia is typically measured arterially and is a PaO2 below 80 mmHg.
