  1. 1. You do not need, and will not be able to, in clinical practice, give local anaesthetic before doing ABG. they are done primarily in emergency situations and when venous sampling is unsuitable and 2. You should engage the needle safety device by pushing the cover against a surface; definitely not with your finger as theoretically this increases the risk of needle-stick injury.

  2. Gonna drop the Geeky Medics intro at a post-OSCE rave, bust out the robot dance and inevitably be crowned King of the Universe.

  3. Learn clinical skills on the move and support us in producing more awesome videos with the Geeky Medics app https://geekymedics.com/geeky-medics-app/ 👾💉🎉

  4. Very helpful video. Only thing that always worries me when taking ABG samples is the possibility of injury while removing needle and applying firm pressure immediately with the other hand. Is that a thing?

  5. Kindly Explain the No. Of Guage Used during collection of sample and further process after collection of sample !
