Q

non-volatile acids

A

eliminated by kidney’s, except lactic acid (kidney and liver)
lactic acid, phosphoric acid, sulfuric acid, acetoacetic acid, beta-hydroxybutyric acid

17
Q

what is a survivable range of pH

18
Q

3 main types of buffer systems

A

bicarbonate-carbonic acid buffer
phosphate buffer
protein buffer

19
Q

what are buffers?

A

chemicals in body that combine with acid or base to change pH
almost instantaneous, short lived

20
Q

bicarb-carbonic acid

A

located in ECF

21
Q

phosphate buffer

A

main intracellular buffer

cannot measure

22
Q

protein buffers

A

nearly all proteins can function as buffers
carboxyl group
amino acid
acetic acid

23
Q

respiratory mechanisms

A

only work on volatile acids

exhalation excretes carbonic acid

24
Q

what happens to RR and depth during alkalosis

A

body holds onto acids RR and Depth decrease

25
what happens to RR and depth during acidosis
body blows off, RR and depth increase
26
kidney excretion
eliminate large amounts of acid except carbonic acid can also excrete base can conserve and produce bicarb ions if kidneys fail, pH balance fails
27
rates of correction for buffers
instantaneously
28
rates of correction of respiratory
several min to hours | short lived
29
rates of correction of renal
several hours to days, long lived
30
what is compensation
body's response to acid-base imbalance
31
what is complete compensation?
body brought back within normal limits
32
what is partial compensation?
when range is still outside normal limits
33
if underlying cause is metabolic what can help?
hyperventilation or hypoventilations | respiratory compensation
34
if underlying cause is respiratory what can help?
metabolic compensation
35
if acidotic how does the body get back to hemostasis?
stimulates brain and arterial receptors,lungs increase RR and depth, blows off CO2 and increases pH
36
if alkalotic how does the body get back to homeostatsis?
stimulates brain and arterial receptors, lungs decrease RR and depth, holds on to CO2, and pH decreases
