MostCare Versus Echo-Doppler for Cardiac Output Measurement (PRAM)

Patients in Intensive Care Unit, under different clinical conditions

Inclusion Criteria:

• Patients equipped with a standard arterial catheter-line (femoral or radial artery) for invasive arterial blood pressure monitoring.
• Patients requiring an echocardiographic evaluation - Transthoracic Echocardiographic Evaluation (TEE)or Transesophageal Echocardiographic Evaluation (TOE) - as a routine need or in the context of Acute Cardiocirculatory failure with suspected implication of cardiac dysfunction or Acute Respiratory failure and suspicion of cardiac failure.

• *When a pulmonary artery catheter (PAC, standard bolus thermodilution, ThD) is used or a central venous catheter linked with a femoral artery catheter to measure the transpulmonary thermodilution (PiCCO system: Continuous pulse contour cardiac analysis), the comparison will be done as a secondary end point of the protocol.

  • The point n.3 is optional

Exclusion Criteria:

• Related to MostCare:

pathologies that could affect the quality and reliability of the arterial signal (aortic valve pathologies, aortic aneurysms) and arrhythmias that generate hemodynamic instability (i.e., variations in mean BP measurements > 10%); poor quality of the arterial pressure signal after a standard flush test (i.e., over-damped or under-damped arterial trace).

• Related to Echo-Doppler: non-feasibility to obtain a fulfilled quality of the images.
• Patients younger than 18.
