Flashcards in Oxygenation and Mechanisms of Hypoxemia article Deck (6)
Oxygenation is the process of oxygen diffusing passively from the ______ to the ________ ________, where it binds to _______ in red blood cells or dissolves into the plasma.
- pulmonary capillary
Oxygen delivery is the rate of oxygen transport from the ______ to the _______ tissues.
Oxygen consumption is the _______ at which oxygen is removed from the blood for use by the tissues.
There are numerous ways to determine whether oxygenation is impaired and at risk of being insufficient to meet the metabolic requirements of the peripheral tissues. Name 4 of them.
- arterial oxygen saturation (SaO2)
- arterial oxygen tension (PaO2)
- alveolar to arterial (A-a) oxygen gradient
- PaO2/FiO2 ratio
A low partial pressure of oxygen in the blood is termed _______.
