2

AT 12-15% of O2 in the air, what toxicity symptoms does one exhibit?

muscular coordination for skilled movements lost

3

At 10-14% of O2 in the air, what toxicity symptoms does one exhibit?

judgement is faulty and and muscular effort leads to rapid fatigue

4

At 6-8 % O2 in the air, what symptoms are seen?

collapse, rapid treatment would prevent fatal outcome

5

Death occurs in 6-8 at what percent of oxygen?

6 or below

1st degree

8

Characteristics of 2nd degree burn?

blisters, epidermis and dermis- may involve all of dermis
