ABG's

Question 1

Metabolic compensation

Answer 1

METABOLIC COMPENSATION
mechanism by Renal system, in which plasma pH can be altered by varying the excretion/retention of HCO3.
o Occurs in response to respiratory acidosis or alkalosis.
o Slower, yet greater ability to restore norms.

• Metabolic Compensation for a Respiratory Acidosis (hypoventilation high CO2) is to retain and therefore increase HC03
• Metabolic compensation for a respiratory alkalosis (hyperventilation low CO2) is to excrete through the kidneys and decrease HCo3

Question 2

normal ranges of ABG’s

Answer 2

PH 7.34-7.45
Co2 35-45
Hco3 22-26
PaO2 80-100
Hb 12-14 (f) 13-15 (m)
Sa02 95-100%
