Detection Oxygen saturation SpO2 Newborns

项目摘要

About 10% of infants worldwide require some form of stabilization during the process of transition from prenatal (foetal) to postnatal (newborn) life. In healthy infants, oxygen saturation gradually increases over time and is a significant neonatal instrument for determining newborn stabilisation. Hence, monitoring SpO2 could strengthen support transitioning of newborn babies and promote early interventions. However, in a stressful environment of a delivery room, conventional technologies such as pulse oximetry are restricted due to motion artifacts and poor tissue perfusion at the peripheral sites (such as wrist, toes, or fingers) that could potentially delay resuscitation efforts. Additionally, the colour of the patient's skin is a potential factor that may have a negative impact on the accuracy of pulse oximetry. For instance, through the recent COVID-19 pandemic, pulse oximetry measurement error has become a major concern for clinicians measuring SpO2 in individuals with elevated skin pigmentation. It turns out that compared to white skin patients, in patients with other ethnic groups, oxygen saturation measurements obtained from pulse oximeters may be an overestimate of the actual value.Therefore, developing more robust signal processing techniques and advance optical sensors that consider movement artifacts perfusion and ethnicity could improve the delivery of timely medical care from newborns and adults

全世界约有10%的婴儿在从产前（胎儿）到产后（新生儿）的过渡过程中需要某种形式的稳定。在健康婴儿中，氧饱和度随时间逐渐增加，是确定新生儿稳定的重要新生儿工具。因此，监测SpO 2可以加强对新生儿过渡的支持，并促进早期干预。然而，在产房的紧张环境中，由于可能潜在地延迟复苏努力的外围部位（诸如手腕、脚趾或手指）处的运动伪影和不良组织灌注，诸如脉搏血氧测定的常规技术受到限制。此外，患者皮肤的颜色是可能对脉搏血氧测定的准确性产生负面影响的潜在因素。例如，通过最近的COVID-19大流行，脉搏血氧测量误差已成为临床医生测量皮肤色素沉着增加的个体的SpO 2的主要问题。事实证明，与白色皮肤患者相比，在其他种族患者中，脉搏血氧仪获得的血氧饱和度测量值可能高估了实际值。因此，开发更强大的信号处理技术和先进的光学传感器，考虑运动伪影灌注和种族，可以改善新生儿和成人的及时医疗护理
