Flashcards in Renal Acid Base 2 Whole Body Acid Base Balance Deck (20):
1

Give an example of RESP acidosis

Chronic bronchitis
Chronic emphysema
Airway restriction
Chest injuries

2

Uncompensated acidosis is shown by

Ph 45mmHg

3

What is the compensation for RESP acidosis

No ec buffering
Renal system must compensate
Pco2 dives hydrogen ion secretion by kidney
Carbon dioxide retention stimulated the sec of hydrogen ions into the filtrate
Bicarbonate reabs
TA and ammonium inv

4

What does RESP acidosis correction require

Lowering pco2 by restoration of normal ventilation

5

What is rep alkalosis

Excessive removal of carbon dioxide by the body

6

How does reps alkalosis arise

Low inspired po2 at high altitudes -hypoxia stim peripheral chemoreceptors hypervent lowers pco2

Hypervent

Hysterical over breathing

7

Uncompensated RESP alkalosis shown by

Ph> 7.45
Pco2

8

What is the renal compensation for RESP alkalosis

Excessive removal of co2 reduces hydrogen ion sec into tubule
Bicarbonate excreted releasing alkaline urine
No TA or ammonium formed so no new bicarbonate formed

9

How is rep alkalosis corrected

Requires restoration of normal ventilation

10

What is metab acidosis

Most common
Excess hydrogen ions form any source other than Corbin dioxide

11

How can metab acidosis arise

Ingestion of acids or acid pouting foodstuffs
Excessive metab production hydrogen ions
Excessive loss of base from the body

12

How is metab acidosis shown

Ph

13

How is metab acidosis compensated

Via RESP syst
Ventilation quickly increased and more carbon dioxide blown off which caused plasma concentration to be put to normal

14

How is the correction of metab acidosis

Filtered bicarbonate is low and readily abs
Hydrogen ion sec and TA and ammonium cause new bicarbonate form
Acid excreted in urine

15

What is metabolic acidosis

Excessive loss of hydrogen form the body

16

How can metabolic alkalosis arise

Loss HCl form stomach
Ingestion of alkali or alike prod foodstuffs
Aldosterone hypersecrtion

17

If metab alkalosis uncomp what is shown

Ph> 7.35
Bicarbonate plamsa conc high

18

What is the compensating for metab alkalosis

RESP compensation
Increased ph slows ventilation peripheral chemoreceptors
Carbon dioxide retained so the pco2 rises causing hydrogen ion conc of plasma to rise lowering the ph

19

What is the correction of metab alkalosis

Filtered bicarbonate load so large compared to normal not all filtered bicarbonate is reabs
No TA or ammonium
Bicarbonate exported in urine
Fall back to norm

20

What is RESP acidosis

Retention of carbon dioxide by the body
Build up in blood meaning more carbonic acid produced increasing the acidity
