Figure 8. In real time, the effect of CO2 inhalation on LDF flow and REG signals: CO2 concentrations were accompanied by increases in LDF flux and REG signal amplitudes. The Y axis is given in volts for all traces, whereas the X axis is shown in seconds. REG raw signal; REG proc (processed signal, presented as a running integral); EKG; Respiration (measured by bioimpedance); LDF flux; inhaled CO2 are the traces, from top to bottom .
