ABSTRACT:
Determining the hydrogen content of the expiratory air of a person using a sample holder and a hydrogen detector. Expiratory air is passed through the sample holder in order to obtain an expiratory air sample. A pressurized gas is then introduced into the sample holder and directs the expiratory air through the hydrogen detector at a fixed flow rate as determined by the pressure of the pressurized gas.
