Ⅳ CUTOFF MECHANISM FOR LOW RESOURCE SETTINGS

摘要

Intravenous (Ⅳ) fluid regulation is necessary in developing nations to prevent Ⅳ-overhydration in the pediatric patients of low-resource hospitals. Traditionally, regulation is achieved by calculating the total fluid outflow from an IV bag and restricting flow before the patient is injected with dangerous levels of fluid. However, standard fluid regulation devices include infusion pumps and burettes, which are costly and often ill-suited for low-resource environments. This research proposes a low-cost, easy to use device that regulates the volume of intravenous (Ⅳ) fluid delivered to a patient in a low-resource clinical setting. Laboratory accuracy tests (N=32J over a range of clinically-relevant fluid volumes yielded a median and max error of 4 and 8mL respectively, falling within specific error thresholds (p
