概括
接近红外光谱 (NIRS) 设备对乳房切除皮肤透的监测有希望. 然而,根据皮肤颜色的不同,准确度会有所不同,可能会高估黑色皮肤的氧化度.
科学领域:
- 生物医学工程
- 外科瘤学
- 医学成像
背景情况:
- 精确监测乳房切除皮层 (MSF) perfusion 对于患者的结果至关重要.
- 组织缺血在MSF可能难以检测,特别是在皮肤颜色较暗的患者.
- 近红外光谱 (NIRS) 提供实时组织氧和 (StO2) 测量,但需要对各种皮肤色调进行验证.
研究的目的:
- 评估SnapshotNIR NIRS设备在不同皮肤色素水平上的精度.
- 为了确定菲茨帕特里克皮肤色素评分对组织氧化的NIRS测量的影响.
- 识别与皮肤色相关的NIRS读数中的潜在偏差.
主要方法:
- 一项涉及33名乳腺切除术患者的准实验性研究.
- 使用快照NIR装置测量MSF边缘 ΔStO2 (手术前减去手术后的StO2).
- 与菲茨帕特里克皮肤色素评分相关的 ΔStO2 的分析.
主要成果:
- 在菲茨帕特里克得分和ΔStO2之间观察到显著的负相关性 (ρ = - 0. 392, p = 0. 016).
- 随着菲茨帕特里克分数的增加,组织氧化量 (ΔStO2) 逐渐下降,表明氧化量从增加到减少的转变.
- 在皮肤颜色较浅和较深的组之间发现了显著的ΔStO2差异 (菲茨帕特里克得分为1比5和2比5).
结论:
- 快照NIR技术可以检测StO2的变化并预测缺血.
- 在皮肤颜色较暗的个体中,NIRS设备可能会高估组织氧化.
- 对NIRS设备进行校准是必要的,以确保对所有皮肤颜色进行准确的输液监测.

Special considerations while measuring oxygen saturation
697
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.

Pulse Oximetry
407
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...
