I want to know about ABG(artrial blood gases).

Question

I want to know about the ABG (arterial blood gases).what is normal ABG.how to make out a ABG.WHAT SHOULD WE DO TO CORRECT ABG.

Answer 1

An arterial blood gas (ABG) test measures the acidity (pH) and levels of oxygen and carbon dioxide in the blood.  ABG's are done to check for severe breathing problems and lung diseases, such as asthma, cystic fibrosis, or chronic obstructive pulmonary disease.

The normal range is:

pH: 7.35–7.45

Partial pressure of oxygen (PaO2): 75–100 mm Hg

Partial pressure of carbon dioxide (PaCO2): 35–45 mm Hg

Bicarbonate (HCO3): 20–29 mEq/L or 20–29 mmol/L

Oxygen content (O2CT): 15%–22% (15–22 mL per 100 mL of blood)

Oxygen saturation (O2Sat): 95%–100% (95–100 mL per 100 mL of blood)



Abnormal results may be caused by many different reasons such as diabetes, drug or alcohol overdose, kidney failure, lung diseases, such as pneumonia or severe dehydration from severe burns, vomiting, diarrhea, or taking water pills (diuretics), severe infection (sepsis).  Your ABG levels should be stabilized with appropiate respiratory therapy such as oxygen theraphy or with the use of more advanced mechanical ventilation.  I guess It depends on the situation.
