Component of #ABG (arterial blood Gas) is explained in this video.
which are:
#pH
PaO2
PaCO2
HCO3
SO3
Other components

pH
The pH measures hydrogen ions (H+) in blood. The pH of blood is usually between 7.35 and 7.45. A pH of less than 7.0 is called acid and a pH greater than 7.0 is called basic (alkaline). So blood is slightly basic.
The partial pressure of oxygen (PaO2).
This measures the pressure of oxygen dissolved in the blood and how well oxygen is able to move from the airspace of the lungs into the blood.

The partial pressure of carbon dioxide (PaCO2).
This measures the pressure of carbon dioxide dissolved in the blood and how well carbon dioxide is able to move out of the body.
Bicarbonate (HCO3).
#Bicarbonate is a chemical (buffer) that keeps the pH of blood from becoming too acidic or too basic.

Oxygen content (O2CT) and oxygen saturation (sO2) values.
O2 content measures the amount of oxygen in the blood. Oxygen saturation measures how much of the hemoglobin in the red blood cells is carrying oxygen (O2).

Now when we understand the basic components of ABG, we will move forward with the ABG analysis and clinical significance along with the diagnostic approach.
