Flashcards in Cardiac & Resp. - ABGs Deck (20):
1

pH

7.35-7.45

2

acidotic

pH below 7.35

3

alkolotic

Ph above 7.45

4

PaCO2

35-45 mm Hg

5

HCO3

22-26 mm Hg

6

PaO2

80-100 mm Hg

7

respiratory

- acidotic and PaCO2 is above normal
- alkolotic and PaCO2 is below normal

8

metabolic

- acidotic and PaCO2 is normal or below
- alkolotic and PaCO2 is normal of above

9

respiratory alkalosis - symptoms

tingling of extremities, confusion, deep & rapid breathing and seizures

10

respiratory alkalosis - causes

- hyperventilation, anxiety, hypoxia, pregnancy and high altitudes

11

metabolic alkalosis - symptoms

- nausea & vomiting, diarrhea, restlessness, slow respirations, arrhythmias

12

metabolic alkalosis - causes

- GI symptoms, loss of gastric juices, overuse of antacids, potassium wasting diuretics

13

metabolic acidosis - symptoms

- disorientation, Kussmaul respirations, muscle twitching and changes in LOC

14

metabolic acidosis - causes

- diabetes, shock, sepsis, salicylate overdose, renal failure

15

respiratory acidosis - symptoms

- rapid & shallow respirations, dyspnea, disorientation, muscle weakness

16

respiratory acidosis - causes

- COPD, hypoventilation, drug overdose, pulmonary edema, chest trauma, neuromuscular disease

17

respiratory acidosis

- hypoventilation where not enough CO2 is being blown off
- kidneys try to compensate by retaining bicarbs thus elevating the HCO3

18

metabolic acidosis

- imbalance of the body's acids and bases except CO2
- loss of base or and excess of acids is caused by diabetic ketoacidosis, diarrhea or renal failure
- respiratory system tries to compensate by increase rate and depth to try and blow off CO2 to reduce acid

19

respiratory alkalosis

- hyperventilation where too much CO2 is blown off
- can be from anxiety, fear, fever or improper vent mgmt.
- body tries to compensate by allowing the kidneys to excrete increased bicarbs

20

metabolic alkalosis

- imbalance of the body's acids and bases except CO2
- loss of acid or gain of base occurs from Na bicarb ingestion, vomiting, or NG suction
- lungs try to compensate by decreasing respiratory effort to conserve CO2
