An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring for patients with critical illnesses or respiratory disease.
P a CO 2 – Partial pressure of carbon dioxide at sea level in arterial blood is between 35 and 45 mmHg (4.7 and 6.0 kPa). [9] Venous blood carbon dioxide tension. P v CO 2 – Partial pressure of carbon dioxide at sea level in venous blood is between 40 and 50 mmHg (5.33 and 6.67 kPa). [9]
The alveolar gas equation is the method for calculating partial pressure of alveolar oxygen (p A O 2).The equation is used in assessing if the lungs are properly transferring oxygen into the blood.
If lack of oxygenation is proportional to low respiratory effort, then the A–a gradient is not increased; a healthy person who hypoventilates would have hypoxia, but a normal A–a gradient. At an extreme, high CO 2 levels from hypoventilation can mask an existing high A–a gradient. This mathematical artifact makes A–a gradient more ...
The alveolar oxygen partial pressure is lower than the atmospheric O 2 partial pressure for two reasons.. Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg.
The formation of a bicarbonate ion will release a proton into the plasma, decreasing pH (increased acidity), which also shifts the curve to the right as discussed above; low CO 2 levels in the blood stream results in a high pH, and thus provides more optimal binding conditions for hemoglobin and O 2. This is a physiologically favored mechanism ...

In humans, about a third of every resting breath has no change in O 2 and CO 2 levels. In adults, it is usually in the range of 150 mL. [3] Dead space can be increased (and better envisioned) by breathing through a long tube, such as a snorkel. Although one end of the snorkel is open to the air, when the wearer breathes in, they inhale a ...
