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

Figure 4

The representative patient data. Four LFCT curves were overwritten. We normalized the voltage difference to make each LFCT value clear in this figure. We calculated the maximum difference between R and IR to 1 and minimum to 0 in each session. The patient was measured LFCT for 4-times. There were clear singular nadirs in LFCT curves. Each LFCT value was 16.14, 16.50, 16.96, and 16.76 (seconds), respectively. This case showed high reproducibility of LFCT. LFCT: lung to finger circulation time, R: red light, IR: infrared light.
