...David J. Sandstrom; Bruce W. Offord ABSTRACT Coulometric respirometry is a highly sensitive method for measuring O 2 consumption in small organisms but it is not in widespread use among physiologists. Here, we describe a coulometric microrespirometer based on a digital environmental sensor inside...

... hypothesized therefore that partitioning of CO 2 would shift to the air phase in severe aquatic hypoxia, eliminating the risk of branchial O 2 loss. By adapting a respirometer designed to measure aquatic Ṁ O 2 / Ṁ CO 2 , we were able to run intermittent closed respirometry on both water and air phase for both...
