Cardiac Surgery, Cardiopulmonary Bypass, Extracorporeal Circulation
Conditions
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.
Interventions
PROCEDURENon-invasive blood pressure oscillometer (NIBP) implementation
Implementation of two additional NIBP on humeral and femoral sites.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Measurement of femoral, radial and humeral pulses during a cardiopulmonary by-pass (CPBP). | 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. |
