Postural orthostatic tachycardia syndrome (POTS) is a disabling condition characterized by orthostatic intolerance with tachycardia in the absence of drop-in blood pressure. A custom-built near-infrared spectroscopy device (NIRS) is applied to monitor the muscle oxygenation, noninvasively in patients undergoing incremental head-up tilt table (HUT). Subjects (6 POTS patients and 6 healthy controls) underwent 30[Formula: see text]mins of 70 on a HUT. The results showed a significant difference in deoxyhemoglobin (Hb), change-in-oxygenation [Formula: see text] and blood volume [Formula: see text] between patients and healthy controls. However, oxyhemoglobin (HbO2) showed a significantly faster rate of change in the healthy controls during the first 10[Formula: see text]mins of the tilt and during the recovery. This NIRS muscle oximetry tool provides quantitative measurements of blood oxygenation monitoring in diseases such as POTS.

体位性心动过速综合征患者的近红外光谱肌血氧测定



体位性直立性心动过速综合征 (POTS) 是一种致残性疾病,其特征是在没有血压下降的情况下不能耐受直立性心动过速。定制的近红外光谱装置 (NIRS) 用于无创监测接受增量平视倾斜台 (HUT) 的患者的肌肉氧合情况。受试者(6 名 POTS 患者和 6 名健康对照)接受 70 次 30[公式:见文本]分钟∘在小屋里。结果显示,患者和健康对照者之间的脱氧血红蛋白 (Hb)、氧合变化 [公式:见正文] 和血容量 [公式:见正文] 存在显着差异。然而,氧合血红蛋白 (HbO 2 )显示,在倾斜的前 10[公式:见文本]分钟和恢复过程中,健康对照组的变化率明显更快。这款 NIRS 肌肉血氧测定工具可对 POTS 等疾病的血氧监测进行定量测量。
