Flashcards in Acid-Base Imbalance Deck (15):
1

How do we test for acid-base imbalance?

ABGs

2

What is alkalosis?

A pH greater than 7.45

3

What is acidosis?

A pH less than 7.35

4

What are the four types of acid-base imbalances?

Metabolic acidosis/alkalosis and respiratory alkalosis/acidosis

5

What is H2CO3? Does it stay in the body for long

It is a volatile acid that is immediately converted into C02 by the lungs

6

What is the difference between respiratory acidosis/alkalosis and metabolic acidosis/alkalosis?

Metabolic: involves fixed acids such as lactic acid
Respiratory: involves volatile acid

7

What is respiratory imbalance?

C02 elimination problem.

8

In respiratory imbalance what does impaired ventilation result in?

Increased levels of pC02 which leads to a decrease in pH causing respiratory acidosis

9

In respiratory imbalance what results from excess C02 elimination?

A decrease in pC02 lead in to an increased pH and respiratory alkalosis

10

What levels are increased or decreased in metabolic acidosis?

Increased fixed acid (H+) or decreased base (HC03)

11

Why is pH a critical variable?

Proteins can only function within a narrow pH range, they can become denatured and then loss of function occurs

12

What levels are increased or decreased in metabolic alkalosis?

Increased base (HC03) or decreased H+ ions

13

How do the kidneys compensate for alkalosis?

Reabsorption of HC03

14

Which body systems compensate for eachother and by compensation what results?

Lungs compensate for kidney and vice versa, normalized pH occurs

15

Tx for acid-base imbalance?

PO and IV solution to normalize pH, but need to treat underlying problem causing acidosis or alkalosis
