Arterial Blood Gas Values Chart (ABG Values and Meanings)

Arterial Blood Gas (ABG)

Oxygen and Carbon Dioxide are the main gases dissolved in our blood. There is more oxygen in arterial blood, while there is more Carbon Dioxide in Venous blood. Arterial Blood Gas (ABG) test measures the acidity (pH) and levels of oxygen and carbon dioxide in the blood. The normal values of ABG differ in people living at different height from sea level. So normal values of ABG in New York might differ from normal ABG values in Washington DC. We will provide Arterial Blood Gas Value chart for people living at sea level. If your ABG differ from it, then refer to normal value shown by the lab in your locality. Don't conclude a result after checking the values in your ABG test report. If you find the values differ a lot, then its better to get it verified by a doctor.

Sometimes we try to know what is the meaning of ABG test values. Here we will try to tell the meaning of Arterial Blood Gas Values. Arterial Blood Gas test measures the following things in blood. We are providing the normal range of their values for those people living at sea level height.

Arterial Blood Gas Values Chart

  • Partial pressure of oxygen (PaO2): Greater than 80 mm Hg (greater than 10.6 kPa)
  • Partial pressure of carbon dioxide (PaCO2): 35–45 mm Hg (4.6–5.9 kPa)
  • pH: 7.35–7.45
  • Bicarbonate (HCO3): 22–26 mEq/L (22–26 mmol/L)
  • Oxygen content (O2CT): 15–22 mL per 100 mL of blood (6.6–9.7 mmol/L)
  • Oxygen saturation (O2Sat): 95%–100% (0.95–1.00)

Which conditions can affect your Arterial Blood Gas Values

  • If you are having abnormally high or low body temprature, i.e. Fever or hypothermia.
  • Anemia or polycythemia which affects the oxygen carried by blood.
  • Active or passive smoking just before test can affect test adversely.
  • A closed room which is freshly painted or varnished can also affect the result.
