Hypoxia And Hypoxaemia

Question 1

What is tissue hypoxia

Answer 1

Low oxygen at tissue level

Question 2

What is Hypoxaemia

Answer 2

Low oxygen in blood

Question 3

What are the potential symptoms of tissue hypoxia

Answer 3

Altered mental state 
Tachypnoea 
Hypoventilation 
Arrythmias 
Peripheral vasodilation 
Nausea 
Vomiting 
Coma

Question 4

What are the types of hypoxia

Answer 4

Hypoxic- low oxygen in lungs
Anaemic- low haemoglobin
Ischemic- low circulation
Histotoxic- low tissue oxygen utilisation

Question 5

What percentage of oxygen is bound to haemoglobin

Answer 5

98%

Question 6

What is oxygen saturation (sa02)
