    Arterial blood gas (ABG) interpretation helps medical professionals, including nurses, make better decisions about patient care. That’s why ABG meaning is an integral part of nursing learning.

    What Does ABG Mean?

    An arterial blood gas (ABG) test measures the oxygen and carbon dioxide levels in the blood and the pH balance. It’s used to evaluate how well patients’ lungs are working.

    Normal ABG Values

    • Arterial blood pH – 7.38 to 7.45
    • Bicarbonate (HCO3) – 22 to 26 milliequivalents per liter (mEq/L)
    • Partial pressure of oxygen (PaO2) – 75 to 100 millimeters of mercury (mmHg) or 10.5 to 13.5 kilopascal (kPa)
    • Partial pressure of carbon dioxide (PaCO2) – 35 to 45 mmHg or 5.1 to 5.6 kPa
    • Oxygen saturation (O2Sat or SaO2) – 94 to 100%

    I cannot express enough gratitude for Nurse Mike and this wonderful platform he has created. I had a subscription to SimpleNursing the entire 2 years of my nursing school career and… it was the best resource I had available to me. The visuals, the explanations, the memory tricks, the songs, the study guides, and the test questions are brilliant.

    Before starting nursing school, I was a C-average student. I didn't think I'd be competent enough and make it through my second semester. I was told about SimpleNursing and… purchased it immediately. Long story short, I graduated nursing school with honors and passed all of my classes with As and Bs only. I would have never been able to do that without the help of SimpleNursing. Nurse Mike teaches in the only way that I am able to learn and I cannot thank him enough.
