• Sex: All
• Target Recruitment: 20

Inclusion Criteria

Age > 18. Ability to offer informed consent. Undergoing cardiac surgery requiring cardiac bypass from the perfusion machine.

Exclusion Criteria

Previous surgery involving the great blood vessels including aorta or carotid arteries. Patients in whom the cardiac surgeon considers enrolment will be inappropriate due to high surgical risk, patients with intraaortic balloon pump, known peripheral vascular disease.

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The ptimary outcome is the agreement between assessors as to the time of return of pulsatile flow on 2D and colourDoppler ultrasound assessed by interrelator agreement[time of the detection of pulsatile flow]

Secondary Outcome Measures

Name	Time	Method
The secondary outcome will be the MAP when pulsatile flow first detected by 2d or colourDoppler by inter-relator agreement. [Time when pulsatile flow visible on arterial line trace]
