Arterial Blood Gas Interpretation Flashcard

Front

What does a low PaO2 level indicate in terms of oxygenation?

Back

Inadequate oxygenation.

Front

What is the primary acid-base disturbance seen in respiratory alkalosis?

Back

Decreased carbon dioxide (CO2) levels.

Front

What is the normal range for pH in arterial blood gas?

Back

7.35-7.45.

Front

What acid-base disturbance is indicated by a decreased PaCO2 level and decreased HCO3 level with a normal pH (7.45)?

Back

Respiratory alkalosis.

Front

What is the significance of PaO2 in arterial blood gas interpretation?

Back

PaO2 measures the amount of oxygen dissolved in the blood and indicates the effectiveness of oxygenation.

Front

What is the role of carbon dioxide (CO2) in acid-base balance?

Back

CO2 is a component of the bicarbonate buffer system and helps regulate blood pH.

Front

What does a pH level below 7.35 indicate?

Back

Acidosis.

Front

What does a pH level above 7.45 indicate?

Back

Alkalosis.

Front

What is the relationship between respiratory rate and CO2 levels in respiratory alkalosis?

Back

Increased respiratory rate leads to decreased CO2 levels.

Front

What is the bicarbonate (HCO3) normal range in arterial blood gas?

Back

22-26 mEq/L.
