Assessing pulse pressure to estimate stroke volume in critically ill patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate the ability of pulse pressure to predict stroke volume in critically ill patients using bedside echocardiography. The researchers hypothesize that pulse pressure can effectively identify low stroke volume and monitor changes during various cardiovascular interventions. By measuring pulse pressure from an arterial line alongside left ventricular outflow tract velocity time integral, the study will gather comprehensive clinical, hemodynamic, and echocardiographic data. This approach seeks to improve the management of cardiovascular dysfunction in emergency and intensive care settings.
