About

This study evaluates the role of arterial tone in the accuracy of cardiac output (CO) measurement by Pressure Recording Analytical Method (PRAM). Patients receiving noradrenaline who need for clinical reason to change the noradrenaline dose will be enrolled. We use echocardiography as reference method of CO measurement.

Full description

Pressure Recording Analytical Method (PRAM) is an arterial pulse contour analysis method for CO measurement. As it is an uncalibrated method, one possible reason for its inaccuracy is rapid changes in arterial tone.

Enrollment: 31 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• invasive blood pressure monitoring on site
• need to start or change the dose of noradrenaline infusion for clinical reason
