ABG Flashcard

Front

What does HCO3 represent in an ABG analysis?

Back

HCO3 represents bicarbonate, which is primarily regulated by the kidneys and indicates metabolic processes.

Front

What does CO2 represent in an ABG analysis?

Back

CO2 represents carbon dioxide, which is primarily regulated by the lungs and indicates respiratory processes.

Front

What is the normal range for the partial pressure of oxygen (PaO2) in the blood?

Back

The normal range for PaO2 is 80-100 mmHg.

Front

What does pH measure in the context of ABG analysis?

Back

pH measures the concentration of hydrogen ions in the blood, indicating acidity or alkalinity.

Front

What is the normal range for carbon dioxide (CO2) in the blood?

Back

The normal range for CO2 is 35-45 mmHg.

Front

What is the significance of a low pH in ABG results?

Back

A low pH indicates acidosis, which can be due to either respiratory or metabolic causes.

Front

What is the significance of a high pH in ABG results?

Back

A high pH indicates alkalosis, which can also be due to either respiratory or metabolic causes.

Front

How do the kidneys compensate for respiratory acidosis?

Back

The kidneys compensate for respiratory acidosis by increasing bicarbonate reabsorption and hydrogen ion excretion.

Front

How do the lungs compensate for metabolic alkalosis?

Back

The lungs compensate for metabolic alkalosis by decreasing the rate and depth of breathing to retain CO2.

Front

What is the role of bicarbonate in the blood?

Back

Bicarbonate acts as a buffer to maintain pH balance in the blood.
