23

hypomagnemia

24

Acid -base basics

body wants a ph of 7.4

CO2 and bicarb maintain this

if bicarb drops- ph goes how

if ph high -high bicarb or low CO2


when ph is too low=acidosis
pCo2 is high and HC03 is low

When ph is too high = alkalosis
HCo3 is high and Pco2 is low

respiratory: alteration in pc02
metabolic - alteration in Hc bicarb ( kidneys)

when on system fails--> other system kick in

25

metabolic acidosis

ph is low, bicarb issue
too much H ion then positive ion gap

compensation: increased ventilation ( kassuma)

tx: fix underlying cause

26

metabolic alkalosis

high bicarb and high ph

causes: due to loss of H or too much bicarb

vomiting , aggressive suction of gastric content

compensation; dec ventilation to increase pC02

s/sx; associated with low CA and low K

tx: fix underlying cause and associated metabolic problems
IV fluids

27

respiratory acidosis

low ph, high Co2
- causes: COPD, narcotic overdose

compensation: reabsorption of bicarb by kidneys

tx; fix underlying cause
naloxone

28

resp alkalosis

low co2 and high ph

cause: hysterical hyperventilaion, salicylate intoxication, PE

sx: rapid breathing, lightheadedness, perioral paresthia

compensation; incr eliminate of bicarb by kidney
