In questa sezione ci concentriamo invece sull\u2019<strong>umidit\u00e0<\/strong>.<\/p>\n<div>\n<p>La pelle pu\u00f2 essere esposta a diversi fluidi corporei, come urina, feci, essudato, sudore o una combinazione di questi, creando talvolta un ambiente umido\u00b9. Se la pelle rimane a contatto con tali sostanze per un periodo prolungato, pu\u00f2 diventare raggrinzita e morbida. Questo porta alla <strong>macerazione<\/strong>, rendendo la pelle pi\u00f9 suscettibile ai danni da frizione e allo sviluppo di ulcere da pressione\u00b9.<\/p>\n<\/div>\n<p>Uno dei ruoli fondamentali della pelle sana \u00e8 fornire una barriera naturale che impedisca le infezioni batteriche\u00b9. Tuttavia, se un paziente \u00e8 incontinente, l\u2019urea presente nell\u2019urina pu\u00f2 alterare l\u2019ambiente cutaneo favorendo la crescita batterica\u00b9.<br \/>\nLe feci contengono inoltre enzimi che degradano la barriera cutanea, rendendo la pelle pi\u00f9 vulnerabile\u00b9.<br \/>\nL\u2019incontinenza urinaria e\/o fecale modifica il pH naturale della pelle, causando arrossamento e deterioramento. Questa irritazione viene definita macerazione, escoriazione o dermatite associata all\u2019incontinenza\u00b9. L\u2019esposizione a tali fluidi corporei pu\u00f2 contribuire significativamente allo sviluppo delle ulcere da pressione.<\/p>\n<p>Implicazioni per la progettazione delle superfici<br \/>\nQuando si considerano le superfici e i dispositivi di supporto, \u00e8 essenziale valutare l\u2019impatto dell\u2019umidit\u00e0 sulla pelle e scegliere materiali in grado di trasmettere il vapore acqueo (come i rivestimenti dei materassi con caratteristiche di permeabilit\u00e0 al vapore). <a href=\"https:\/\/www.medstrom.com\/solution\/temperature-control-in-bariatric-patients\/\">Per i pazienti plus-size,<\/a>\u00a0l\u2019effetto dell\u2019umidit\u00e0 pu\u00f2 essere amplificato a causa dell\u2019aumento della sudorazione. In questi casi, tecnologie come i materassi a <strong>bassa perdita d\u2019aria<\/strong> (ad esempio TurnCair 1000) sono spesso preferibili, poich\u00e9 consentono la circolazione di aria fresca al di sotto del paziente.<\/p>\n<p>Click the links below to read the rest of this series:<\/p>\n<p><span style=\"color: #2a317a;\"><strong>Leggi le altre parti della serie<\/strong><\/span><\/p>\n<p><a href=\"https:\/\/www.medstrom.com\/it\/solution\/science-of-surfaces-parte-1-ulcere-da-pressione\/\">Parte 1: Come si formano le ulcere da pressione?<\/a><\/p>\n<p><a href=\"https:\/\/www.medstrom.com\/it\/solution\/the-science-of-surfaces-series-part-2\/\">Parte 2: Pressione<\/a><\/p>\n<p><a href=\"https:\/\/www.medstrom.com\/it\/solution\/the-science-of-surfaces-series-part-3\/\">3: Scivolamento e Frizione<\/a><\/p>\n<h5>Riferimenti<\/h5>\n<h6>1.
