Overview
Brief Summary
Central and peripheral arterial pressure decoupling occurs in some clinical conditions like sepsis or cardiopulmonary bypass. This decoupling may leed to unsuitable decisions such as the use of catecholamines.
The aim of this study is to evaluate the pulse wave's speed as a marker of central and peripheral arterial pressure decoupling in a scheduled condition which is the cardiopulmonary bypass during cardiac surgery.

Eligibility Criteria
Inclusion Criteria
- •Scheduled patient for coronary or valvular surgery with cardiopulmonary bypass
- •Cardiopulmonary bypass is at least 90 minutes
- •Written consent is needed
Exclusion Criteria

- •Dobutamine/milrinone/levosimendan treatment before surgery
- •Patient with heart rate due to a pacemaker
Outcomes
Primary Outcomes
Measurement of femoral, radial and humeral pulses during a cardiopulmonary by-pass (CPBP).
Time Frame: Day one (6 times)
Pulse wave's speed is calculated using 1) time between ECG R-wave and local detection of the pulse wave (femoral, humeral and radial) 2) a length from heart to these sites. Wave detection at femoral and humeral sites will use oscillometry and wave detection at radial site will use an invasive catheter which is always set for this surgery.
