To the editor: The critically ill patient often needs a vasopressor for hemodynamic support. In addition, because fluids are often limited to such patients, higher concentrations of the various agents are used to help maintain their hemodynamic balance. When the new concentrated fluid is hung, the intravenous tubing is frequently not changed but the tubing already threaded through the infusion controller is used. This tubing contains a volume of fluid of the lower concentration and some time passes before this volume is cleared from the tubing and the patient receives the increased dose. This fact must be kept in mind
