A public utility specialist went down into a sewer well without protection and after a while lost consciousness. Ambulance doctors diagnosed him with hydrogen sulfide intoxication. What type of hypoxia developed?

Answer options

1. Hemic
2. Circulatory
3. Overload
4. Tissue
5. Respiratory

Explanation

The basis of this hypoxia(hemic) type is a decrease in blood oxygen capacity. There are two variants: anemic and toxic. Toxic form arises in case of hemic toxins poisoning. The general content of hemoglobin in the blood remains normal, but the contents of functionally active hemoglobin decrease. The part of hemoglobin turns into such compounds, which are not capable to execute oxygen transport function.
