Clearance and Saturation of Hydrogen Gas in Man with Special Emphasize on the Brain,
Abstract
Hydrogen gas clearance and saturation in the brain have been monitored in 22 subjects. The half time for hydrogen gas clearance/saturation in the human brain may fluctuate between 1/2 minute and 30 minutes in grey matter and between 6 - 14 minutes in white matter. The half time for hydrogen gas clearance and saturation in the ear-lobes may vary from 1 to 5 minutes, and from 2 to 20 minutes in the skeletal muscles. 8% CO2 added to the breathing air caused a drastic reduction of the half time for saturation/clearance in certain areas in the brain. Changes in respiration produces great fluctuation in the half time for gas clearance and saturation. Changes in blood flow in general or focal to some areas of the body produce drastic changes in the half time for gas clearance and saturation to the involved area.
