Study Notes
Arterial Puncture Sites
-
Radial artery: Located on the thumb side of the wrist. Considered the safest site for arterial puncture due to the presence of collateral circulation, which means there are alternate routes for blood flow if the radial artery is blocked.
-
Brachial artery: Located on the medial side of the antecubital fossa (the bend of the elbow). Considered a disadvantageous puncture site due to the risk of damage to the median nerve and brachial artery.
-
Femoral artery: Located in the groin area. Considered advantageous due to ease of access and large size, however it's close to a major vein and does not have collateral circulation, increasing the risk of complications.
Blood Gas Values
-
Arterial blood gas (ABG) measures blood levels of oxygen and carbon dioxide in the arteries.
-
pH: Normal range for arterial blood gas (ABG) is 7.35 - 7.45.
-
pO2: stands for partial pressure of oxygen.
