How do you take an ABG step by step?
How do you take an ABG step by step?
Procedure Steps
- Introduce yourself to the patient.
- Equipment required for measuring arterial blood gases.
- ABG kit contents.
- Locate the radial artery with your index and middle fingers.
- Allens Test.
- Remove the cap from the needle.
- Prepare to insert the needle.
- Remove the needle.
How do you collect an ABG sample?
The sample can be obtained either through a catheter placed in an artery, or by using a needle and syringe to puncture an artery. These syringes are pre-heparinized and handled to minimize air exposure that will alter the blood gas values.
What are the 6 steps to ABG analysis?
Six-step program
- Analyze the pH.
- Analyze the PaCO2.
- Analyze the HCO3.
- Match either the PaCO2 or the HCO3 with the pH.
- Determine whether the PaCO2 or the HCO3 go in the opposite direction of the pH.
- Analyze the PaO2 and SaO2 for hypoxemia.
What color tube is used for ABG?
Red top tube with no additive. 4. Other no additive tubes. 5.
Why is ABG placed 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.
Why do we zero arterial lines?
Zeroing the arterial line ensures that only the actual pressures from the patient will be measured by the transducer, thus providing accurate data on which to base treatment decisions.
Why is heparin used in ABG?
Heparin prevents blood from clotting because the unique pentasaccharide sequence contained within its structure binds avidly to antithrombin III.
How do you remember the order of draw?
The order of draw is an order of tubes phlebotomist should follow to prevent testing complications and cross-contamination of additives. The order of draw is Yellow, Light Blue, Red, Light Green, Dark Green, Lavender, and Gray. Way to remember this is by the saying Your brother Robert gives lovely gifts.
What size needle is used for ABG?
ABG syringe, for an adult, use a 20-gauge, 2.5-inch needle for a femoral sample and a 22 gauge, 1.25-inch needle for a radial artery puncture, Also 23 gauge and 25 gauge needle can be used.
Which artery is most frequently used for ABG collection?
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.
Can you put saline in an arterial line?
Normal saline solution can maintain patency of arterial catheters and central venous pressure monitoring catheters.
