Q

What are indications for Arterial Blood Gases?

A
  • Evaluate adequacy of ventilation (PaCO2), oxygenation (PaO2), and pH (acid-base)
  • Determine response to therapeutic intervention (supplemental O2, mechanical ventilation, and diagnostic evaluation)
  • Monitor severity and progression of a disease process

Q

What are the hazards of ABG punctures/needles?

A
  • Infection of technician (needle stick to self)
  • Inappropriate medical treatment (wrong patient diagnosis)
  • Vessel spasm (constriction of blood flow)
  • Hematoma (localized bleeding)
  • Hemorrhage (internal bleeding)
  • Vasovagal reaction (vagus nerve response-syncope)
  • Laceration of the artery
  • Loss of limb
