2 Clinical Trials for Various Conditions
The purpose of this study is to examine how the heart functions when a calculated amount of blood is removed and how two fluids, Lactated Ringer's (considered the standard replacement fluid) and Hypertonic Saline, re-expand the vascular system.
The overall goal of this multicenter project is to characterize the expected normal range of Peripheral IntraVenous Volume Analysis (PIVA) values during a euvolemic state, and how those ranges may be altered by comorbidities; the relationship between PIVA and intravenous volume administration during resuscitation of infected patients with presumed hypovolemia; and, the relationship between PIVA and volume decreases during diuresis in acute heart failure patients with hypervolemia.
