Abstract

Objectives: This study is performed to determine the effects of fluid height, inner catheter diameter, and peripheral venous pressure on room-temperature intravenous fluid administration.

Methods: We employed the Bernoulli equation, with frictional forces considered for volumetric analysis.

Results: The results of this study demonstrate that infusion-set height, catheter size, fluid type, and blood pressure significantly affect flow rates. Under normotensive conditions, flow rates ranged from 58.2 to 10,743.18 cc/h, with the highest rates observed at a 1 m infusion-set height and larger catheters. Additionally, 6% hetastarch exhibited the lowest flow rates, while 0.9% normal saline showed the highest. Under hypertensive conditions, slightly higher infusion-set elevations were required for measurable flow rates, but they remained lower than those under normotensive conditions.

Conclusion: This study investigates the mechanics of peripheral venous fluid therapy and provides foundational data for future nursing research on fluid management.

正常和高血压情况下液体流速随液体高度和导管尺寸的比较。
目的:本研究旨在确定液体高度、导管内径和外周静脉压对室温静脉输液的影响。方法:采用伯努利方程,考虑摩擦力进行体积分析。结果:本研究结果表明,输液器高度、导管尺寸、液体类型和血压对血流速率有显著影响。在常压条件下,流速范围为58.2至10,743.18 cc/h,在输注高度为1 m和导管较大时观察到的流速最高。6% hetararch流速最低,0.9%生理盐水流速最高。在高血压情况下,为了测量血流速率,需要稍微高一些的输注高度,但它们仍然低于正常情况下的血流速率。结论:本研究探讨了外周静脉输液治疗的机理,为后续输液护理研究提供了基础数据。

期刊介绍: Healthcare (ISSN 2227-9032) is an international, peer-reviewed, open access journal (free for readers), which publishes original theoretical and empirical work in the interdisciplinary area of all aspects of medicine and health care research. Healthcare publishes Original Research Articles, Reviews, Case Reports, Research Notes and Short Communications. We encourage researchers to publish their experimental and theoretical results in as much detail as possible. For theoretical papers, full details of proofs must be provided so that the results can be checked; for experimental papers, full experimental details must be provided so that the results can be reproduced. Additionally, electronic files or software regarding the full details of the calculations, experimental procedure, etc., can be deposited along with the publication as “Supplementary Material”.
