1

% of water loss through eating

20%

2

80%

3

% of water intake through metabolism of food

10%

4

Respiration
Sweating

5

Vomit & diarrhoea

6

What % of total body weight is water

60%

7

What % of water in the body is extracellular

20%

8

% of intercellular water

40%

9

% of interstitial fluid

15%

10

% of intavascular water

5%

11

Causes for primary causes of water depletion

Lack of water supply
Unable to drink
Excessive panting
Pyrexia/fever
Diabetes insipidus

12

Causes for mixed water depletion

Vomiting
Diarrhoea
Third spaced fluid loss
Burns
Wounds

13

Considerations of fluid therapy

Route of fluid therapy
Choice of vein
Choice of fluid e.g. blood products, colloids, crystaloids
Choice of giving set

14

What is shock

State of acute circulatory collapse where the circulation is unable to transport sufficient oxygen to meet the tissues

15

Types of shock

Hypovolaemic
Obstructive
Cardiogenic
Distributive (SIRS/anaphylactic)

16

Hypovolaemic shock

Due to loss of circulating blood volume causing decrease in tissue perfusion

17

Causes of hypovolaemic shock

Haemorrhagic
Vomiting
Diarrhoea
Severe dehydration
Neoplasia
Burns
Polyuria

18

Obstructive shock

Rare
Obstruction of blood flow from heart or venous return to the heart
Must occur in a vessel close to heart to cause deficit in tissue ivy Ben delivery

19

Causes of obstructive shock

Pulmonary thromboembolism
Pericardial effusion - increased intrapericardial pressure reduces blood flow to right side of heart
