The response to parenteral solutions was investigated in critically ill patients, with the use of indicators of ventricular preload by echocardiography, in 36 patients admitted to the hospital as critically ill, comorbid history, hemodynamic parameters, blood test data and echocardiographic measurements were taken before volume expansion, patients who increased their systolic volume and cardiac output greater than 15% after expansion were considered as responding, 300 cc. Of lactated Ringer's lactate was used as an expander.

25% of the patients did not respond to volume, in them the history of diabetes was a conditioning factor, among the parameters tested that we analyzed; Right Ventricular Tele Diastolic Volume (VTDVD), Left Ventricular Tele Diastolic Area (ATDVI) were significantly lower in those who responded compared to those who did not, by ROC curve was obtained that, VTDVD has an area under the curve of 0. 98 (P=0.
