• For each patient included in the study, the secondary variables will be noted in the patient's data collection logbook.
• This is followed by radial artery cannulation (if absent), and connection to the HemoSphere/EV1000 platform
• After the daily visit, the PI/collaborating investigators (CI) will measure the clinical, treatment, and mechanical ventilation parameters of the patient during the last 24 hours.
• Daily arterial analysis will be requested
• This information collection process will be followed for 5 days. At the end of the information collection period, the IP will perform two downloads, the engineering download, and the standard download in which the values are monitored every 20 seconds.
• These will be noted in the secondary variables of the data collection logbook, along with the patients' ICU discharge date.
• In-hospital mortality will be monitored during admission to a conventional hospital ward.
• Records will be closed upon discharge of the patient.

Hypotension will be defined as a hemodynamic event that occurs when the MAP falls below 65 mmHg for a minimum duration of 1 minute (3 consecutive recordings of 1 minute or more between two consecutive falls of the MAP).

We will obtain hemodynamic data for the first 5 days after the patient enters the study
