How is arterial blood gas calculated?

ABG Components:

1. pH = measured acid-base balance of the blood.
2. PaO2 = measured the partial pressure of oxygen in arterial blood.
3. PaCO2 = measured the partial pressure of carbon dioxide in arterial blood.
4. HCO3 = calculated concentration of bicarbonate in arterial blood.

What is the measure of ABG?

An arterial blood gas (ABG) test measures the acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. This test is used to check how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood.

Why is PCO2 high?

The most common cause of increased PCO2 is an absolute decrease in ventilation. Increased CO2 production without increased ventilation, such as a patient with sepsis, can also cause respiratory acidosis. Patients who have increased physiological dead space (eg, emphysema) will have decreased effective ventilation.

What is the normal value of arterial blood gas?

Values that fall outside of the normal range, as well as shifts in blood pH that occur as a result are referred to as abnormal blood gases. The first step in evaluating a blood gas report is to look at pH. The normal range for arterial blood pH is 7.35 to 7.45.

What is the normal range of arterial blood?

The normal range for arterial blood pH is 7.35 to 7.45. A pH greater than 7.45 indicates alkalosis or more alkaline blood and a pH below 7.35 indicates acidosis or more acidic blood.

What is the normal range of blood gas?

The first step in evaluating a blood gas report is to look at pH. The normal range for arterial blood pH is 7.35 to 7.45. A pH greater than 7.45 indicates alkalosis or more alkaline blood and a pH below 7.35 indicates acidosis or more acidic blood . When the pH is greater than 7.0, the blood is alkaline and when it is less than 7.0, acidic.

What is normal blood gas results?

The following are normal ranges for results of a blood gas test: pH: 7.35–7.45. partial pressure of oxygen (PaO2): 80–100 millimeters of mercury (mmHg) partial pressure of carbon dioxide: 35–45 mmHg. bicarbonate: 22–26 milliequivalents per liter. oxygen saturation: 95 percent.
