In the context of support surfaces, 'envelopment' refers to the extent to which the support surface conforms to the shape of the patient. This concept is crucial because when a support surface adequately envelops the patient, it helps to distribute the patient's weight more evenly and reduces localized pressure points. This reduces the risk of pressure injuries, as the even distribution mitigates the pressure exerted on any specific area of the body. When a surface does not conform well to the patient's body, it can create areas of high pressure, leading to complications like skin breakdown and pressure ulcers. Therefore, understanding envelopment is essential for selecting appropriate support surfaces that enhance patient comfort and safety.
