Shock
Reliability of Respiratory Variability of Maximal Aortic Blood Flow Velocity Obtained by Ultrasonography-doppler in Patients Followed Up with a Diagnosis of Shock in Intensive Care Unit for Evaluating Fluid Responsiveness in Patients
Original value: Shock is an important cause of mortality in intensive care units (ICU). Determining whether shock patients will benefit from (intravenous) IV fluid therapy is possible by fluid responsiveness parameters/tests.
