ABG sampling
Informed by recognized medical guidance
Overview
Arterial Blood Gas (ABG) sampling is a test that measures oxygen and carbon dioxide levels in your blood, along with its acidity (pH). It helps doctors check how well your lungs are working and if your body is getting enough oxygen.
Key facts
- ABG sampling uses blood from an artery, not a vein, to get more accurate oxygen levels.
- The test helps diagnose breathing problems and monitor treatments.
- Results can show if you need extra oxygen or help with breathing.
ABG sampling is a common test used in hospitals, especially in emergency rooms and intensive care units.
It is usually done on people who have difficulty breathing, serious lung or heart conditions, or who are critically ill.
