Quantification of pulmonary edema (ELWI, PVPI) and analysis of hemodynamic parameters with PiCCO

www.getinge.co...
The PiCCO Technology provides quantification of the amount of pulmonary edema, expressed as extravascular lung water index (ELWI).
The life of critically ill patients depends on the right decision for the next therapeutic step. Therapeutic conflicts often arise at the critical care bedside, where dependable information is needed. A set of reliable hemodynamic parameters can help determine the best individual treatment. In this video our Senior Clinical Application Specialist shows all hemodynamic parameters provided by the PiCCO Technology, pointing out lung related parameters such as Extravascular lung water index (ELWI) and Pulmonary vascular permeability index (PVPI) that enable intensive care physicians to quantify pulmonary edema and also identify the reason.
Extravascular lung water index (ELWI)
A pulmonary edema is characterized by an accumulation of fluid in the interstitium of the lung tissue and / or the alveoli. This leads to impaired gas exchange and may even cause pulmonary failure. The amount of the pulmonary edema can be quantified at the bedside by measuring the extravascular lung water index (ELWI).
When pulmonary edema is present, the next important question is: What is the reason for the pulmonary edema? In general there are two main sources of pulmonary edema.
1. Cardiogenic pulmonary edema - Caused by intravascular fluid overload, hydrostatic pressure increases. This causes fluids to leak into the extravascular space.
2. Permeability pulmonary edema - Vascular permeability is increased by an inflammatory reaction caused, for example, by sepsis. This leads to the increased transfer of fluids, electrolytes and proteins from the intravascular to the extravascular space, even with a normal to low intravascular fluid status and hydrostatic pressure.
