Experimental validation of frequent used echocardiographic right ventricular impedance parameters.
Aim of the study was to validate commonly used bedside right-ventricular (RV) impedance parameters, which are utilized in determining heart-lung interactions during mechanical ventilation. ⋯ ACmean is a reliable parameter of RV impedance that can be used to study the heart-lung interactions during mechanical ventilation.

Dysnatremia on intensive care unit admission is a stronger risk factor when associated with organ dysfunction.
Dysnatremia present at the time of intensive care unit (ICU) admission is associated with mortality. In this study, we investigated the epidemiology of dysnatremia present on ICU admission and the impact of organ dysfunction on the association between dysnatremia and mortality. We hypothesized that dysnatremia comorbid with organ dysfunction is associated with higher risk of mortality. ⋯ Below 125 and above 150 mmol/L sodium levels at ICU admission are risk factors for higher mortality rates in patients with comorbid organ dysfunction. The effect of dysnatremia on mortality is observed when organ dysfunction is present.
