To determine if a condition is due to a respiratory imbalance:

a) pco2 values will have a corresponding relationship to the pH values

b) HCO3 values reflects a corresponding relationship to pH

c) pco2 values reflect an oppositional relationship to pH

d) HCO3 values have an oppositional relationship with pH
Respiratory imbalances reflect pco2 values that have an oppositional relationship to pH

low pH - high pco2 = respiratory acidosis

high pH - low pco2 =
respiratory alkalosis

if pco2 values don't reflect an oppositional relationship to pH then the condition is most likely a metabolic imbalance and HCO3 values will be noted

respiratory = opposite & note pco2

metabolic = same & note HCO3

a) 22-27 mm Hg

b)80-100 mm Hg

c)35-45 mm Hg
80-100 mm Hg = pO2 norm
