Arterial blood gases (ABG), whole blood
Collect arterial blood in a heparinized syringe, and send to laboratory immediately.
Blood gas measurements provide information about cardiopulmonary (oxygen and carbon dioxide exchange) and metabolic (acid-base) status. When integrated with the history and physical examination, the rapidly available arterial blood gas (ABG) analysis is useful in the care of the acutely ill or injured patient.
See Carbon Dioxide, Oxygen, and pH.
In addition to the measurement of pH and partial pressures of oxygen and carbon dioxide, the bicarbonate concentration is calculated.
