Abstract

Near infrared spectroscopy (NIRS) is a technique whereby light is transmitted to the skin or the surface of a wound. Light is selectively absorbed or reflected in order to calculate the percentage of oxygenated and deoxygenated hemoglobin. By calculating this ratio, the level of tissue oxygen perfusion can be assessed. This article describes an NIRS imaging device and demonstrates its use as a clinical tool to predict future viability of skin flaps, potential for wound healing, and progress of closure following application of a biologic wound product. Several cases are examined.

摘要

近红外光谱（NIRS）是一种将光传输到皮肤或伤口表面的技术。光被选择性地吸收或反射，以计算氧合血红蛋白和脱氧血红蛋白的百分比。通过计算该比率，可以评估组织氧灌注水平。本文描述了一种NIRS成像设备，并展示了其作为临床工具在预测皮瓣未来存活能力、伤口愈合潜力以及应用生物伤口产品后伤口闭合进展方面的用途。文中检查了几个病例。
