Unconscious in bathroom , worth preventing.

Yesterday I went to a post graduate institute for a clinical meeting where they presented patients who went for a bath , & were recovered from the bathroom in unconscious state sometimes even after three hours. They were investigated for neurological & other causes for this .
Even the MRI showed changes. Some including a doctor were also started on anti epileptic medicines thinking it to be a seizure! It was systematic analysis with high index of suspicion which revealed that it was happening due to Gas Geyser in the bathroom. In winters generally the bathroom windows are closed especially while bathing . This results in accumulation of Carbon monoxide(CO) -a gas which has 250 times more affinity for Hemoglobin in blood than oxygen ( O2). Co typically competes with O2 , not only attaches itself to hemoglobin but also displaces it form hemoglobin. This results into severe oxygen deprivation of brain and unconsciousness.
If at all you must install a gas geyser it should be out side the bathroom.Bathroom windows must be open for ventilation. GO FOR SOLAR ENERGY.!
