Q
What is hyperaemia?
A
Increased blood within vessels of a region
2
Q
What is active hyperaemia?
A
Increased input (arteriolar dilation)
3
Q
What is passive hyperaemia?
A
Decreased venous drainage “congestion”

A
Decreased vascular perfusion
6
Q

A
Hypovolaemia
7
Q
Localised ischaemia
A
Obstruction to blood flow by intralumenal vascular obstruction
8
Q
What is hypoxia?
A
Poor oxygenation of alveoli
9
Q
What is anaemia?
A
Inadequate oxygen carrying capacity (haemoglobin) of the blood
