Lung-to-finger circulation time can be measured stably with high reproducibility by simple breath holding method in cardiac patients

Abstract Lung to finger circulation time (LFCT) has been used to estimate cardiac function. We developed a new LFCT measurement device using a laser sensor at fingertip. We measured LFCT by measuring time from re-breathing after 20 s of breath hold to the nadir of the difference of transmitted red l...
