Modified Allen Test for Arterial Blood Gas (ABG) Procedure Collection Blood Draw

The modified Allen test is a simple test used to determine whether collateral blood flow exists to the hand. The modified Allen test is performed before collecting an arterial blood gas from the radial artery.
The test ensures that blood flow is adequate to the hand in case there is a problem during collection from the radial artery.
The modified Allen test is performed by occluding the radial and ulnar arteries with your thumbs. The patient can make a fist and open and close the hand. This will cause the skin color to lighten or become "blanched."
Next, you release pressure on the ulnar artery. if the hand returns to its normal color within 5 seconds, the result is considered normal. You can usually proceed with radial artery ABG sampling.

Hi Sarah, my name is Esther and I am a registered nurse in CA. I just wanted to take some time to say thank you for all of the content that you have created. We are so blessed to have someone like yourself creating amazing resources for students and nurses. I also wanted to ask for prayers. I am in a process that I currently don't understand. I took some time off from bedside and I am currently seeking work. Its early right now for me, about 4 AM approximately. I am praying God will help me. However, I don't want to think he has forgotten about me.
Anyways. I am a brand ambassador. I recently recommend a few people to your content. I really admire your ethical standards and your passion for helping others. Thank you. -Esther

Hello Esther! Thank you for the kind comment. It means a lot to me. I wanted to write back and let you know I seen your comment this morning. I have prayed for you. Don't give up and know that our God is faithful and He loves you very much and has not forgot about you. Philippians 4: 6-7 reminds me of this, and I love these verses when I need His encouragement 💜

Thank you! I am a RT student and needed a refresh on how to do the Allen’s test correctly. Any way you can do a video on setting up Arterial Line and inserting an A-Line in a patient? Thank you for helping this RT student!

Quick question when you're entering in your continuing education credits and it's half an hour I'm noticing it shows up as 0 on the board website... how do I get credit for my works?
