概括
接近红外光谱 (NIRS) 足部测量根据皮肤类型和位置而异. 较暗的皮肤 (菲茨帕特里克皮肤类型6) 在脚部显示较低的氧和度.
科学领域:
- 生物医学工程 生物医学工程
- 皮肤病学 皮肤病学
- 医疗成像医学成像
背景情况:
- 近红外光谱 (NIRS) 是一种非侵入性的光学技术,用于测量组织氧化.
- 对于足部评估NIRS的规范性数据是有限的,特别是考虑到皮肤色素和解剖位置的变化.
- 菲茨帕特里克皮肤类型 (FST) 是一种广泛使用的皮肤色素分类系统.
研究的目的:
- 建立对NIRS测量脚背部和脚部表面的规范性数据.
- 评估菲茨帕特里克皮肤类型 (FST) 对NIRS参数 (氧和,氧血球,脱氧血球) 的影响.
- 为了比较脚的背部和脚部区域之间的NIRS测量.
主要方法:
- 招募了110名健康的志愿者.
- 通过在背部和脚底部的SnapshotNIR设备获得NIR测量.
- 根据菲茨帕特里克皮肤类型 (FST 1-6) 和脚部区域分析了数据.
主要成果:
- 在背部脚部,患有FST 6的个体表现出明显较低的氧和氧血球蛋白比较较浅的皮肤类型 (FST 1-5).
- 不同的FST之间在足部脚部上没有观察到NIRS参数的显著差异.
- 与背部脚相比,在足部发现了更高的氧血球和脱氧血球水平,而氧气和度没有差异.
- 没有NIRS数据的区域主要在FST 5-6的背部脚部,在FST 6的区域明显更大.
结论:
- 菲茨帕特里克皮肤类型对背部脚部的NIRS测量有重大影响,因此在临床应用中需要考虑皮肤色素.
- 在皮肤颜色较暗的个体中,特别是背部脚部,应谨慎解释NIRS数据.
- 未来的NIRS研究应该将皮肤色素作为一个关键的共同变量用于准确解释结果.

Guidelines For Measuring Vital Signs
1.6K
Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

Pulse Oximetry
328
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Special considerations while measuring oxygen saturation
592
Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.

IR Frequency Region: Fingerprint Region
887
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...
