acid base balance Flashcards
carbon dioxide is
carbon diACID
hydrogen ions are
HI acid
bicarbonate
bi base
common ground with
COMpensation
if patient vomits or has too much ng tube suctioning,
they are getting rid of acid, so our body has more base. This is alkylosis.
kidneys get rid of
hydrogen ions, which are acidic.
if our kidneys are broken, we have too much acid. we have acidosis.
intestines hold base (if it comes out your ass-icosis, then you’ll be in acidosis)
bicarbonate. so if pt poops out all the base, they have only acid left and becomes acidosis.
dka - diabetic ketoACIDOSIS
easy
respiratory acidosis (RR is sloooooow in acidooooosis)
low and slow RR (causes sleep apnea, head trauma) CNS depressants - dope and alcohol, benzos. pneumonia - bad gas exchange.
(CO)PD retains more
(CO)2
panic attack - hyperventilation
blow off CO2 and acid. then you have alkylosis.

compensated v uncompensated
always look at pH first.
fully compensated: pH is in normal range
uncompensated: pH is not in normal range
partially compensated
pH not in normal range, but CO2 and HCO3 are high - trying to work it out.
full compensated
ph normal, CO2 and HCO3 high
uncompensated
ph is not normal and CO2 is high
kidneys control
bicarbonate and H (acid)
kidneys regulate acid base by
excreting H in the urine, and retaining more base - bicarb
if kidneys fail, then
acid prevails. we can’t get rid of H, so we go into acidosis
if we vomit or have an ng tube, we get rid of
H (acid), and we get alkylosis
