. The measurement of hydrogen (H 2 ) in breath is becoming increasingly useful as a diagnostic and research tool, but there is still no satisfactory method of sampling expired air in infants and small children. We tested a modified open‐flow hood method where the child's head is put in a perspex box and expired air is collected by sucking air from the box by means of an air pump. Comparison of this method with end‐expiratory sampling by a modified Haldane‐Priestly and nasopharyngeal catheter gave a correlation coefficient of 0.83 and 0.65, respectively, We conclude that expired air sampling in children with this method is a more satisfactory and as reliable a method as any available at present, and has the added advantage of being quantitative.
