Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 2: Cardiopulmonary bypass blood gas management will be conducted utilising a CDI 500, the current blood gas management protocol, however the CDI 500 will be used real time to influence perfusion management (intervention).

The control group (group 1) is current the current managment with the addition of the monitoring device (CDI 500) in the circuit. The output of the device is not accessible during the case.

Summary
Brief summary
Cardiopulmonary bypass is a procedure used for cardiac surgery. Currently during bypass we need to monitor blood gases to make sure we are oxygenating your blood. This monitoring, currently involves taking samples from the heart lung machine and sending them off for results.
We plan to assess a new device, that we can place on the heart lung machine, that will allow us to get blood gas results immediately and so we can act upon these straight away.

The aim of this study is to assess the ability of the CDI 500 blood gas monitor to detect blood gas parameters during your surgery. In addition, this study will assess the impact on outcomes of the use of this monitor.
