W5100 ethernet shield and cooking hacks e-health SPO2 sensor

Hello all;

The cooking hacks V2.0 e-health sensor shield and W5100 ethernet shield are incompatible when using the SPO2 sensor and an Arduino Uno. I am inquiring if there is a way to get these three devices to function so readings can be sent to a database and if not why this can't be done.

Regards,
