Recently, an uncalibrated minimally invasive Pulse-code Modulator (PCM) has been developed: the MostCare system. This monitoring system is powered by Pressure Recording Analytical Method (PRAM), which is based on the mathematical analysis of the arterial pressure profile changes. It allows beat-to-beat Stroke Volume (SV) assessment from the pressure signal recorded invasively in radial, brachial, or femoral arteries. The most innovative features of this method are: 1) the lack of a calibration requirement, 2) the analysis of the arterial wave signal is performed at 1000 Hz, 3) a dedicated arterial catheter-transducer is unnecessary. MostCare is powered by PRAM (Pressure Recording Analytical Method) algorithm. The investigators primary end-point was to evaluate the relationship between Cardiac Output (CO) measured by MostCare with CO calculated with Echo-Doppler in Intensive Care Unit (ICU) patients under different clinical conditions. As a secondary end-point the investigators evaluated the relationship between CO measured by MostCare with CO obtained with thermodilution techniques (standard bolus thermodilution or transpulmonary thermodilution, i.e. PiCCO system). This is a prospective multicentre observational study.

Study Population

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.
