项目摘要
Abstract
Wearable pulse oximetry sensors are among the most ubiquitous medical technologies used in healthcare.
Clinicians rely on pulse oximeters to monitor patient health during disease states and medical procedures.
However, numerous studies have shown this technology to be racially biased; hypoxemia is three times more
likely to go undetected in patients with dark skin compared to those with light skin. This technological deficit
disproportionately impacts people of color in the United States and contributes to minority healthcare disparities.
The FDA has since issued a safety warning about using pulse oximetry for minority populations. Low blood oxygen
levels can signify serious respiratory illness in a patient and healthcare workers rely on pulse oximeters to
determine what type of care a patient needs. False negative hypoxemia diagnosis can have detrimental
consequences for patient care including increased rates of mortality and organ dysfunction. The widespread and
impactful use of these devices highlights a critical need for innovative technology that improves healthcare equity
and mitigates racial bias in pulse oximetry. Despite well-documented racial biases, a 2022 survey of pulse
oximeter technology found no manufacturers attempting to incorporate novel technology that accounts for
differences in skin tone. The goal of this Phase I project is to develop novel sensor technology for non-invasively
measuring blood oxygen saturation that accounts for the patient’s skin pigment and delivers reliably accurate
oxygen saturation measurements for persons of all skin colors. Our proposed technology incorporates two
sensing modules: a novel skin pigment colorimetry sensor for classifying patient skin tone and an optical
transducer for measuring blood oxygen saturation via the photoplethysmography technique. We will develop a
machine learning algorithm to model and compensate for the effects of skin tone on blood oxygen saturation
measurements. These innovations in technology development and biological signal processing will meet a critical
need for a medical device that provides accurate blood oxygen saturation monitoring for persons of all skin colors.
摘要
可穿戴脉搏血氧饱和度传感器是医疗保健中最普遍使用的医疗技术之一。
临床医生依靠脉搏血氧仪在疾病状态和医疗程序期间监测患者健康。
然而,许多研究表明,这项技术是种族偏见;低氧血症是三倍以上,
与浅色皮肤的患者相比,深色皮肤的患者更容易被检测到。这种技术缺陷
不成比例地影响美国的有色人种,并导致少数民族的医疗保健差异。
此后,FDA发布了关于少数群体使用脉搏血氧仪的安全警告。低血氧
水平可能意味着病人患有严重的呼吸系统疾病,医疗工作者依靠脉搏血氧仪,
确定患者需要什么样的护理。假阴性低氧血症诊断可能对
对患者护理的后果包括死亡率和器官功能障碍的增加。普遍和
这些设备的有效使用凸显了对创新技术的迫切需求,以改善医疗保健公平性
并减轻脉搏血氧测定中的种族偏见。尽管存在有据可查的种族偏见,但2022年对脉搏的调查显示,
血氧计技术发现,没有制造商试图采用新技术,
肤色的差异。这个第一阶段项目的目标是开发新的传感器技术,
测量血氧饱和度,考虑到患者的皮肤色素,
所有肤色的人的血氧饱和度测量。我们提出的技术结合了两个
传感模块:用于对患者肤色进行分类的新型皮肤色素比色传感器和
用于通过光电体积描记技术测量血氧饱和度的传感器。我们将开发一个
机器学习算法,用于建模和补偿肤色对血氧饱和度的影响
测量.这些技术开发和生物信号处理方面的创新将满足一个关键的
需要为所有肤色的人提供准确的血氧饱和度监测的医疗设备。
