Body builders or people with increased BMI may exhibit low diastolic pressure with wide pulse pressure due to large muscle mass. The decline in the diastolic pressure contributes to a greater drop in total peripheral resistance in response to exercising.This facilitates in the escalation of stroke volume and ultimately the cardiac output, enabling enhanced physical performance and aerobic capacity. Some aerobically athletic people like distance runners experience progressive decline in the diastolic while the systolic rises.Some individuals experience progressive rise in systolic pressure while doing aerobic exercise whereas their diastolic pressure remains same.It is normal to have widened blood pressure after or during exercising, which will go back to normal within 10 minutes. Below we will discuss the causes in detail. It has been explained before what exactly happens in the body when people experience widened or widening pulse pressure. Occurrence of both the above conditions.And if it exceeds 60, then you may be at risk of developing a cardiovascular disease.īased on its relationship with systolic and diastolic blood pressure, there are three factors that may contribute to this: Pulse pressure above 40mmHg is categorized as wide pulse pressure. What Is Considered as Widened Pulse Pressure? At times certain conditions result in widened pulse pressure that may be problematic. For instance if the blood pressure is 120/80mmHg, then the pulse pressure is 40, which is considered as the normal pulse pressure. The numeric difference between these two readings is regarded as pulse pressure. Pulse pressure is related with both systolic and diastolic pressure. The upper reading represents the systolic pressure, i.e.,the maximum pressure exerted by the heart when it beats or pumps blood to the organs.The lower reading represents diastolic pressure, i.e., the pressure generated in the arteries between the heart beats. Published by Elsevier Inc.The values of blood pressure are read in two numbers: the upper reading and the low reading. Hypotension Narrow pulse pressure Pulse pressure Severe trauma Trauma team activation criteria.Ĭopyright © 2021. Prehospital narrow PP should be recognized as a proxy for major trauma in patients with heightened surgical and interventional needs so that appropriate in-hospital preparations may be made prior to patient arrival. Although prehospital narrow PP is not currently a TTA criterion, these patients have a mortality rate and ISS intermediate to those of hypotensive and normotensive patients. Prehospital narrow PP independently predicts severe trauma, resuscitative thoracotomy, and emergent intervention. On multivariable analysis, prehospital narrow PP was independently associated with resuscitative thoracotomy (OR 1.609, p=0.009), emergent intervention (OR 1.356, p=0.001), and NFTI (OR 1.237, p=0.009). Mortality was highest among the Hypotensive (n=130, 12%) followed by Narrow PP (n=92, 5%) and Normotensive patients (n=502, 1%) (p<0.001). ISS was higher among Narrow PP and Hypotensive patients (5 vs. Penetrating trauma was more frequent among Narrow PP and Hypotensive patients (23% vs. Univariable/multivariable analyses compared outcomes and determined independent predictors of mortality resuscitative thoracotomy emergent intervention and need for trauma intervention (NFTI), a contemporary measure of major trauma. Others (herein referred to as Normotensive). Prehospital blood pressure defined study groups: Narrow PP (<30 mmHg) vs. Exclusions were unrecorded prehospital/ED vitals, age 60, transfers, on-scene cardiac arrest, and missing discharge disposition. Patients presenting to our ACS-verified Level I trauma center (2008-2020) were retrospectively screened. This study examined the impact of prehospital narrow PP on outcomes after trauma. Narrow PP in the Emergency Department (ED) has recently been shown to predict hemorrhagic shock after trauma. The pulse pressure (PP) is the difference between systolic and diastolic blood pressures.
