Card Set Information
ABG blood gas analysis
true or false.
When HCO3 is raised so is the base excess.
True. This occurs in metabolic alkalosis. A respiratory alkalosis would have a raised pH with low CO2. BE and HCO3 may be normal or low if the body has compensated.
Normal HCO3 range
22-26. (remember a number in the 20s is normal)
Normal range for BE?
-2 TO +2.
When >+2 indicates a metabolic alkalosis or a compensated respiratory acidosis (where pH is down, CO2 is up and the bicarb raises to compensate).
Interpret the following:
Compensated respiratory acidosis.
metabolic acidosis (no respiratory compensation as CO2 not increased from hypoventilation)
type II respiratory failure with chronic compensation of raised CO2.
CO2 must be >6.5 in type II with, often hypoxaemia (<8kpa).
