Question

Quizplus · Accepted Answer

Pressure is the main element that causes pressure injury.Three pressure-related factors contribute to pressure injury development: pressure intensity,pressure duration,and tissue tolerance.When the intensity of the pressure exerted on the capillary exceeds 12 to 32 mm Hg,this occludes the vessel,causing ischemic injury to the tissues it normally feeds.High pressure over a short time and low pressure over a long time cause skin breakdown.Resistance (the ability to remain unaltered by the damaging effect of something),stress (worry or anxiety),and weight (individuals of all sizes,shapes,and ages acquire skin breakdown)are not major causes of pressure injury.
