Primary purpose of obtaining ABG samples 1. adequacy of oxygenation 2. adequacy of ventilation 3. reflects lung formation
3 major hazards of arterial puncture 1. bleeding 2. obstruction of vessel. 3. infection
3 major criteria for selection of arterial puncture site 1. collateral blood flow 2. vessel accessibitly 3. peripheral structures
Collateral blood flow If it's part of a colatoral circulation system it can prevent loss of distal blood flow in the event of arterial obstruction
Vessel accessbility the best vessel for puncture is one that is easy to palpate, relatively superficial and somewhat stable
Peripheral structures the best site for arterial punctures are those whcih do not have extremely sensitive adjacent structures such as nerves
The order of preference that sites usually utilize for arterial puncture radial, bronchial, femoral
Allen test elevate hand and make fist for 20 secs, firm pressure held against radial and ulnar arteries, pt opens hand should blanch white, examiner releases only ulnar compression
alternative methods of assessing for collateral circulation doppler ultrasound, and pulse oximetry
Correct procedure for obtaining ABG hold syringe @45 for radial, tell pt "going to feel stick", enter needle quickly, withdraw 1-2 ml, press gauze on site for 3-5 min, check for bubbles, seal syringe while holding site pressure (roll syringe)
Appropriate action to preserve the sample awaiting analyzation put syringe in ice
What should be written on lab slip date, time, pt name, O2 %, temp if abnormal, your initials
Factors that would necessitate holding pressure greater than 5 minutes from arterial puncture pt using anticoagulants, and low platelet counts
