Title:
Orthostatic Vital Signs in Healthy, Young Male Marines
Abstract:
Orthostatic Vital Signs in Healthy, Young Male Marines
Conference Sponsor:Emergency Nurses Association
Conference Year:1996
Author:Greenwood, Mary I., RN, MS, CEN
Purpose: Orthostatic vital signs (VS) are routinely performed in emergency departments in the assessment of hypovolemia. Despite wide use, confusions exist about how to perform the test and what obtained results mean. The purpose of this study is twofold: to pinpoint the optimal times to obtain orthostatic VS data and to describe postural VS changes which normally occur in healthy, well-conditioned, young males. When "normal" orthostatic VS are known, "abnormal" values can be identified and interpreted. Conceptual framework is the physiologic postural tension reflex, a complicated cardiovascular response upon assuming upright positions.

Design: This study is a cross-sectional, quasi-experimental, time series design with subjects serving as their own controls. For every subject, heart rate (HR) and blood pressure (BP) data will be obtained over a period of time, before and after subjects are stood fully upright from a supine position.

Setting: A convenience sampling of 325 volunteer 18-22 year-old male Marines attending SOI will be used. Inclusion criteria include: good health, taking no medications, no history of cardiovascular disease, no smoking or food ingestion in past 2 hours; minimum of 6 hours' sleep in past 24 hours, and no alcohol ingestion or strenuous exertion in past 24 hours.

Methodology: A screening form ensures only individuals meeting the above criteria are included in the study. Non-invasive BP and HR data are obtained through the use of a plug-in computer card, the DynaPulse 2000A (CARDio). Studies examining CARDio against both auscultatory and invasive arterial catheterization BP measurement find CARDio highly accurate and reliable.

Basic Procedure: Subject rests supine for six minutes, while BP and HR VS are obtained every 90 seconds. Subject then stands fully upright for six minutes, and VS measurements continue to be taken every 90 seconds.

Implications: The findings of this research will help identify "normal" orthostatic vital signs. [Research Poster Presentation]
