Acid and Base Balance Flashcards
Low pH
Acidosis
High pH
Alkalosis
What if pH was low and CO2 was high?
Resp imbalance; CO2 Opposite relation from pH
What if pH was high and CO2 was low?
Resp Imbalance; CO2 Opposite relation from pH
What is done if pH and CO2 have similar relationship? ( both high or both are low)
Look at HCO3 and see if it has same relationship to pH
What does it mean if both pH and bicarb (HCO3) are high or both are low?
Metabolic imbalance
Compensated
pH within normal range; body corrected problem
Partially compensated
pH not normal. Look at system that is supposed to fix issue (Respiratory problem-> metabolic system tries to compensate) check for abnormality
Uncompensation
No evidence of supporting systems trying to compensate or partial compensate
Low pH and High CO2
Respiratory acidosis; condition causing airway obstruction or depression
Low pH and Low HCO3
Metabolic acidosis; Insufficient insulin (pt w/ DM=DKA), Severe diarrhea can cause as well
High pH and Low CO2
Respirartory Alkalosis; condition causing overstimulation of Resp System (Hyperventilation, hysteria, overventilation)
Signs of Acidosis
RR increases to try and exhale acids
Signs of Alkalosis
RR decreases to try and retain CO2 to NEUTRALIZE and decrease strength of excess bicarb
High pH and High HCO3
Metabolic alkalosis; GI suctioning or severe vomiting
