| Popis: | The management of ICU patients following heart surgery can be hustling when coping with severe left ventricular (LV) dysfunction. Single beat (Sb) measurements of ventriculo- arterial coupling (VAc) can be used by the intensivist when dealing with altered hemodynamic states [1]. LV elastance (Ees) and arterial elastance (Ea) can be measured by trasthoracic echocardiography (TTE) in a Sb fashion [2], so allowing quick assessment of VAc. PEEP application is common practice in the ICU but can have hemodynamic consequences and lead to instability. Speckle tracking analysis by TTE has been recently reported to help titrating PEEP in critically ill patients [3]. However, this can be demanding and require specific ultrasound tools. In this study we aimed to assess whether standard TTE can be useful in evaluating the effect of respiratory treatment with PEEP on cardiovascular efficiency by measuring VAc after coronary artery bypass surgery (CABG). |
