ARTERIAL PUNCTURE Flashcards
(16 cards)
Used to collect blood specimen for
arterial blood gas (ABG) analysis to
manage cardiopulmonary disorders
ARTERIAL PUNCTURE
Ideal specimen for respiratory function
ARTERIAL BLOOD
(1) OXYGENATION, (2) VENTILATION, and (3)
ACID-BASE balance, which helps in the
management of diseases
ARTERIAL BLOOD GAS (ABG)
Patients with diabetes or other
metabolic disorders also use ABG to
manage the
ELECTROLYTE AND ACID-BASE
BALANCE
Sites and Criteria Used for Arterial
Puncture:
COLLATERAL CIRCULATION
- the site gets its blood supply from more than one artery.
- artery should be accessible and large in size
- The area should be free from inflammation, irritation
Arterial Puncture Sites:
most commonly used site
located in the thumb side of the
wrist
RADIAL ARTERY
Arterial Puncture Sites:
located in the medial anterior of
the antecubital fossa
BRACHIAL ARTERY
Arterial Puncture Sites:
located in the groin lateral to the
pubic bone
FEMORAL ARTERY
Includes the current body temperature,
respiratory rate, ventilation status,
fraction of inspired oxygen (FIO₂),
ABG TEST RESULTS
Patient preparation:
- Identify and explain the procedure
- Prepare patient and assessment
- Steady state
- Allen state (tight fist, apply pressure)
- Administer anesthetic (optional)
The phlebotomist may proceed with the
puncture of the radial artery if there is
COLLATERAL CIRCULATION
Hazards and Complications of Arterial Puncture:
- involuntary contraction of the
artery
ATERIOSPASM
Hazards and Complications of Arterial
Puncture:
results from repeated punctures
on the same site
ARTERY DAMAGE
Hazards and Complications of Arterial
Puncture:
avoid multiple puncture on a single site
HEMATOMA
Hazards and Complications of Arterial
Puncture:
NUMBNESS
THROMBUS FORMATION
Sampling Errors: (4)
- AIR BUBBLES WERE NOT EXPELLED
- EXCEEDED WITHIN 10 MINUTES
- SAMPLES ARE NOT MIXED PROPERLY
- INCORRECT VOLUME OF HEPARIN
