Study Notes
Healthcare Personnel
- Nurses, medical technologists, technicians, respiratory therapists, emergency medical technicians, and level II phlebotomists are involved in arterial puncture and ABG analysis.
Arterial Blood Gas (ABG) Analysis
- Analytes measured in ABG analysis:
- pH: 7.35 – 7.45
- PaO2: 80 – 100 mm Hg
- PaCO2: 35 – 45 mm Hg
- HCO3: 22 – 26 mEq/L
- O2 saturation: 97% – 100%
- Base excess: (-2) – (+2) mEq/L
Criteria for Arterial Puncture Site Selection
- Criteria for selecting an arterial puncture site:
- Collateral circulation or multiple arterial supply
- Accessibility and size of the artery
- Low risk of injury to surrounding tissue
- No inflammation, irritation, edema, hematoma, lesion, or wound
- No arteriovenous fistula (AVF) near the site
- No recent arterial puncture
Arterial Puncture Overview
- Arterial puncture is used to collect blood specimens for ABG analysis to manage cardiopulmonary disorders and maintain acid-base balance.
- Phlebotomists should have thorough understanding of the collection procedure to minimize pain and maintain accuracy.
Hazards and Complications of Arterial Puncture
- Hazards and complications of arterial puncture:
- Arteriospasm
- Artery damage
- Discomfort
- Infection
- Hematoma
- Numbness
- Thrombus formation
- Vasovagal response
ABG Specimen Collection
- Requirements for ABG specimen collection:
- Proper requisition information, including body temperature, respiratory rate, ventilation status, and fraction of inspired oxygen (FIO2)
- Use of personal protective equipment (PPE)
- Necessary equipment and supplies
- Patient preparation and assessment
- Administration of local anesthetic (optional)
Sampling Errors
- Common sampling errors:
- Air bubbles in the sample
- Delayed processing (> 10 minutes)
- Improper mixing or immediate processing
- Improper syringe use
- Venous blood collection by mistake
- Incorrect anticoagulant or heparin volume
