what is acidosis?
pH is low (higher acidity)
what is metabolic acidosis?
high H, low HCO3, low PCO2
condition of metabolic acidosis
diarrhea (losing a lot of your bases)
what is respiratory acidosis?
high PCO2, high H, high HCO3
condition of respiratory acidosis
COPD
what is partial compensation
all values are abnormal (ROME)
what is ROME
respiratory = abnormal value is opposite of pH metabolic = abnormal value is equal to pH
what is complete (total) compensation?
pH is normal, abnormal PCO2 and HCO3
what does uncompensation mean?
pH and another value are abnormal
name this ABG:
pH = 7.20
PCO2 = 30
HCO3 = 24
pH = low (acidosis)
PCO2 = low (alkalosis)
HCO3 = normal
uncompensated respiratory alkalosis
name this ABG:
pH = 7.4
PCO2 = 40
HCO3 = 29
pH = normal
PCO2 = normal
HCO3 = high (alkalosis)
Compensated metabolic alkalosis
name this ABG:
pH = 7.30
PCO2 = 49
HCO3 = 20
pH = normal
PCO2 = high (acidosis)
HCO3 = low (acidosis)
Compensated respiratory acidosis
function of Ca
clotting, muscle contraction
function of Mg
DNA replication, mRNA production, muscle relaxant
function of K
control resting potential
function of Na
regulate extracellular fluid volume, osmolarity
function of ADH
decrease urine production
describe diabetes insipidus
-2 types
not enough ADH
neurogenic = not enough production
nephrogenic = produce enough but no response
RAAS process
Renin (kidneys) + Angiotensinogen (liver) = angiotensin 1 + ACE (lungs) = angiotensin 2
what is SIADH
Syndrome of Inappropriate ADH, too much ADH = decrease in urination
what number determines btw hyper/hypotonic solutions?
above 0.9% = hyper
below 0.9% = hypo
describe hypertonic solution
water moves from intracellular space to intravascular space = cell shrinks
describe hypotonic solution
water moves inside cell = bursts
function of albumin
colloid osmotic pressure (holds stuff inside)
