Abstract
The present invention provides an adapter which actively connects a two terminal oximeter probe or monitor to a three terminal monitor or probe. This is done actively, with the alternating drive signals from the oximeter monitor providing a control signal for switching the adapter connections. The adapter connections are preferably made with diodes, transistors, or other active devices.
