Category 1 This is a category 1 pressure ulcer in brown skin. Note that the erythema (redness) is still visible as the skin is much lighter on the margin of the foot. This image shows non-blanching erythema in white skin.

Category 1: Non blanchable Erythema Intact skin - In lighter skin tones this presents as non-blanchable redness of a localised area usually over a bony prominence.

有机铋聚氨酯催化剂在不同体系中的应用： 1 在密封胶中，建议先试用BiCAT® H，添加量从0.5%开始一次调整，若觉得固化速度快，可试用BiCAT® 8。 2 在喷涂聚脲弹性体中，推荐使用BiCAT® 8，BiCAT® 8118或BiCAT® 8108，添加量为0.2%-0.5%. 3.树脂浆料中推荐使用BiCAT® 8118或BiCAT® 8108。 4.铋锌合金催化剂BiCAT8 (8%铋, 8%锌)替代汞触媒,铋提供固化所需的凝胶速度，高选择性和高速率地生成聚氨酯，锌作为较慢的凝胶催化剂和较好的交联催化剂，可 …

EPUAP - Category /Grade I • Discolouration of the skin: observe for a change of colour a • Non-blanchable erythema of intact skin: persistent redness in lightly pigmented skin. • Warmth, oedema, induration or hardness as compared to adjacent tissue may also be used as indicators, particularly on individuals with darker skin.

2021年8月13日 · 聚酯多元醇是聚氨甲基酸酯（PU）浆料生产中二大主要原料之一，它的品质 好坏 直接影响并决定 PU 浆料质量的优劣； 提高与保证 聚酯多元醇品质，对 PU 浆料生产有十分重要的意义；因此有必要对聚酯多元醇有个清楚的认识。 一、 多元醇的分类：主要分为聚醚多元醇和聚酯多元醇二类。 1 ．聚醚多元醇 主要是以环氧丙烷、环氧乙烷、环氧氯丙烷、二元胺等为原料进行生产的多元醇。 它又可分为：聚氧化丙烯醚多元醇（PPG）、聚四氢呋喃（MPTG）、特种 …

Resource use associated with managing a category 1 PU was substantially less than that associated with managing the other categories of PU. Only 12% of patients were recorded as having seen a specialist physician in the 12 months from initial presentation, of which 65% of the patients had a category 3 ulcer.
