Environmental and behavioral factors that can affect blood pressure
The Nurse Practitioner
|November 1, 1985
Summary
Patient blood pressure fluctuates due to many factors, not always indicating illness. Understanding environmental and behavioral influences is key for accurate health assessments by nurse practitioners.
Area of Science:
- Physiology
- Clinical Assessment
Background:
- Blood pressure (BP) is a vital sign that can exhibit significant variability.
- Numerous non-pathological factors influence BP readings, potentially leading to misinterpretation.
Purpose of the Study:
- To highlight the impact of environmental and behavioral factors on blood pressure.
- To guide healthcare professionals, particularly nurse practitioners (NPs), in accurately interpreting BP measurements.
Main Methods:
- Review of physiological and behavioral factors affecting blood pressure.
- Emphasis on controlling transient variables during BP measurement.
- Evaluation of uncontrollable factors influencing BP.
Main Results:
- Environmental factors (climate, temperature, time of day) affect BP.
- Demographic factors (age, sex) show differences in BP.
- Behavioral factors (body position, activity, diet, substance use, stress) alter BP.
Conclusions:
- Blood pressure variability is common and not always pathological.
- Nurse practitioners must control measurable variables and evaluate unmeasurable ones.
- Accurate interpretation of BP requires consideration of transient influencing factors.
