What are the steps in ABG collection?

Continue to apply firm pressure to the puncture site for 3-5 minutes to reduce the risk of haematoma formation.

1. Flush heparin through the needle.
2. Insert the ABG needle.
3. Advance the needle and observe for flashback.
4. Allow syringe to self-fill.
5. Remove the needle and apply immediate pressure.
6. Engage needle safety device.

Why do we put ABG on ice?

Blood gas samples have been stored on ice for many years to minimize leukocytic metabolism. The cooling effect increases the solubility of oxygen in the plasma and increases the oxygen-hemoglobin affinity.

What are the 6 steps to ABG analysis?

Six-step program

1. Analyze the pH.
2. Analyze the PaCO2.
3. Analyze the HCO3.
4. Match either the PaCO2 or the HCO3 with the pH.
5. Determine whether the PaCO2 or the HCO3 go in the opposite direction of the pH.
6. Analyze the PaO2 and SaO2 for hypoxemia.

What is ABG sampling?

ABG sampling is usually performed on the radial artery because the superficial anatomic presentation of this vessel makes it easily accessible. However, this should be done only after it has been demonstrated that there is sufficient collateral blood supply to the hand.

Which is the first choice artery for ABG collection?

The first choice is the radial artery, which is located on the thumb side of the wrist; because of its small size, use of this artery requires extensive skill in arterial blood sampling.

What happens to an ABG specimen left at room temperature?

Results: There were significant decreases in the pH, PaO2, Na, Cl and significant increases in PaCO2 and K over time in both groups. The changes were greater and faster at room temperature. The significant decrease in pH over time was not found until 30 minutes at room temperature and 45 minutes on ice.

How long can an ABG stay on ice?

There was a further statistically significant decrease in the pH at 30 min in the group of blood samples left at room temperature but not in those in ice. There is no reason to keep arterial blood in ice if blood gas analysis is done within 30 min.

What is the easiest way to understand ABGS?

The first step in ABG interpretation is to look at the pH. Normal blood pH is 7.4, plus or minus 0.05, forming the range 7.35 to 7.45. If blood pH falls below 7.35 it is acidic. If blood pH rises above 7.45, it is alkalotic….6 Easy Steps to ABG Interpretation.
