An enzyme-coupled electrode was incorporated into a catheter to measure the concentration of lactate solutions. The sensor output was found to be linearly dependent on the lactate concentration. The average nonlinearity over a sample of nine catheters was 5.88% full scale. Hysteresis for the device was low, with an average of 4.54% full scale. Preliminary results indicate that in-vivo measurements may be possible, which are not possible with other lactate measurement methods.
