Why you do abg tests?

Arterial blood gas (ABG) tests are performed to assess a patient's oxygenation, carbon dioxide levels, and blood pH, providing critical information about respiratory and metabolic function. They help diagnose conditions such as respiratory failure, metabolic disorders, and acid-base imbalances. ABGs are essential for guiding treatment decisions, especially in critically ill patients or those with respiratory conditions. Additionally, they can monitor the effectiveness of therapies and interventions.
