Abstract
Positive end-expiratory pressure (PEEP) is commonly used to correct hypoxemia in the ICU. However, PEEP may impair right ventricular functions by increasing its afterload. Speckle tracking imaging (STI) is a new echocardiography strain analysis technique that provides direct assessment of myocardial contractility during systole and diastole. The aim of this study was to evaluate the effects of different PEEP levels on right ventricular functions by using STI in patients undergoing coronary artery bypass grafting surgery.

To assess cerebral hemodynamics in an experimental sepsis model
Healthy bowel function is an important factor when judging the advisability of early enteral nutrition in critically ill patients
Sepsis is defined as the presence of infection with systemic signs of infection, and severe sepsis as sepsis plus sepsis-induced organ dysfunction or tissue hypoperfusion [1]
Summary
We evaluated platelet activation markers as potential predictive markers of sepsis and of mortality among four commonly encountered populations of patients admitted to ICUs. Methods Ninety-nine non-infected ICU patients were prospectively screened at day 1 (T1) and day 3 (T2) of admission after elective cardiac surgery, trauma, acute neurologic dysfunction or prolonged ventilation (>48 hours). The present study was performed with the aim of assessing whether nursing and physician staff were able to identify patients in need of critical care using only clinical judgment and to compare this with the National Early Warning Score (NEWS) Methods This was a prospective cohort study of all adult patients with a first-time admission to a medical admission unit at a 450-bed regional teaching hospital over a 3-month period in 2010.
