Online calculator of arterial blood gas (ABG) is a crucial diagnostic test conducted using blood from an artery

An arterial blood gas (ABG) is a crucial diagnostic test conducted using blood from an artery. This test provides essential information regarding the blood’s pH level, the partial pressure of carbon dioxide and oxygen, and the bicarbonate level. ABG analysis aids healthcare professionals in assessing respiratory and metabolic functions, guiding treatment decisions, and monitoring patient health.

    \text{Metabolic Acidosis Compensation: Winters Formula} \\ \text{Arterial oxygen content} = (Hgb \times 1.36 \times \text{SaO}_2) + (0.0031 \times \text{PaO}_2)

     

    where,

    • SaO2 = % of hemoglobin saturated with oxygen (Normal range: 93-100%)
    • Hgb = hemoglobin Normal range(Adults): Male: 13-18 g/dl Female: 12-16 g/dl
    • PaO2= Arterial oxygen partial pressure (Normal range: 80-100)
    • CaO2: Directly reflects the total number of oxygen molecules in arterial blood (both bound and unbound to hemoglobin)
