Carbon monoxide (CO) is emitted by faulty heating equipment as a result of incomplete combustion of carbon based fuel (eg methane).
CO is very toxic and binds with a high affinity to haemoglobin - forming carboxyhaemoglobin (hbCO). This renders erythrocytes incapable of oxygen transport - resulting in damage to body sytems due to hypoxia.
The amount of hbCO in the body and corresponding clinical symptoms are:
> 20 %|
> 30 %
> 60 - 70 %
> 70 %
|Dyspnoea, slight headache|
Severe headache, fatigue and impairment of judgement
Loss of consciousness
