About arterial blood gas..what r the value, how the procedure have to do... What r the components.. What happens if there is any changes in value.

.An arterial blood gas (ABG) test measures the oxygen and carbon dioxide levels in your blood as well your blood's pH balance. The sample is taken from an artery, not a vein, and healthcare providers typically order it in certain emergency situationssituations

pH - This measures the balance of acids and bases in your blood.
Partial pressure of oxygen (PaO2) - This measures the pressure of oxygen dissolved in your blood
Partial pressure of oxygen (PaO2): 75 to 100 mmHg. Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg. Bicarbonate (HCO3): 22-26 mEq/L
ABG Components:
- pH = measured acid-base balance of the blood.
- PaO2 = measured the partial pressure of oxygen in arterial blood.
- PaCO2 = measured the partial pressure of carbon dioxide in arterial blood.
- HCO3 = calculated concentration of bicarbonate in arterial blood.
