The release rate of 37Ar from human subjects following intravenous injection.
Two measurements of the exhalation rate of 37Ar following an intravenous bolus injection have been made on a volunteer, and compared with the exhalation rate of 133Xe for the same subject. The results are also compared with a previously reported pilot 37Ar injection study on a second volunteer. During the first 100 min following injection, the 37Ar washout rate was shown to resemble closely the 133Xe washout rate. This result shows that for short time periods after injection, the behaviour of 133Xe may be used to predict 37Ar behaviour.
