In the TMC SAE, what is the purpose of arterial blood gas (ABG) analysis?

The purpose of arterial blood gas (ABG) analysis is to evaluate the patient's oxygenation, ventilation, and acid-base balance. ABG testing measures the levels of oxygen and carbon dioxide in arterial blood, as well as the pH of the blood, which provides critical information about the respiratory and metabolic status of a patient. This analysis is pivotal for diagnosing conditions such as respiratory failure, metabolic disorders, and for assessing patients in various clinical situations, particularly those with respiratory illnesses, cardiac issues, or disturbances in acid-base balance.

Using ABG results, healthcare providers can determine whether a patient is adequately oxygenated, whether they are retaining or expelling carbon dioxide appropriately, and whether metabolic processes are functioning correctly. These insights guide treatment decisions, such as oxygen therapy, mechanical ventilation, and interventions for acid-base disturbances, making ABG analysis an essential tool in patient management.
