Feedback:
ABGs determine the blood's pH; oxygen-carrying capacity; and levels of oxygen, CO2, and bicarbonate ion. Blood gas samples are obtained through an arterial puncture at the radial, brachial, or femoral artery. A client also may have an indwelling arterial catheter from which arterial samples are obtained. Blood gas samples are not obtained from the pleural surfaces or trachea and bronchi.
