What is an abg Arterial blood gas Drawn from artery- radial, brachial, femoral It is an invasive procedure Caution must be taken with patient on anticoagulants Helps differentiate oxygen deficiencies from primary ventilatory deficiencies from primary metabolic acid-base abnormalities
What is an ABG Arterial Blood Gas Drawn from artery- radial, brachial, femoral It is an invasive procedure. Caution must be taken with patient on anticoagulants. Helps differentiate oxygen deficiencies from primary ventilatory deficiencies from primary metabolic acid-base abnormalities
What Is An abg? pH HI PCO2 Partial pressure CO2 PO2 Partial pressure O2 HCO2 Bicarbonate bE Base excess Sao Oxygen Saturation
What Is An ABG? pH [H+ ] PCO2 Partial pressure CO2 PO2 Partial pressure O2 HCO3 Bicarbonate BE Base excess SaO2 Oxygen Saturation
Acid/Base Relationship This relationship is critical for homeostasis Significant deviations from normal ph ranges are poorly tolerated and may be life threatening Achieved by respiratory and renal systems
Acid/Base Relationship ➢ This relationship is critical for homeostasis ➢ Significant deviations from normal pH ranges are poorly tolerated and may be life threatening ➢Achieved by Respiratory and Renal systems
