Hypoxia

Hypoxia: a condition where there is lack of oxygen reaching the tissues in the body

Causes of hypoxia:

• Impaired ventilation
• Impaired diffusion of gases at lung level
• Impaired pulmonary capillary blood flow
• Impaired transport of gases through blood
• Increased tissue extraction of O2

Acute effects of hypoxia: sleepiness, laziness, false sense of well-being, impaired judgement, blunted pain perception, increasing errors on simple tasks, decreased visual acuity, clumsiness, tremors etc.

I'd like to add another cause of hypoxia: studying. Coz the whole of today I've been feeling sleepy, lazy, falsely satisfied with what I've been studying, judging wrongly how much more I have to know, making errors when answering even simple questions, seeing double when looking at notes etc.

Hopefully I don't get hypoxic when sitting for the test tomorrow...
