    • In a photoplethysmography (PPG) device, a nasal mount includes first and second optical supports (12, 14) secured to a nose (1) with the nasal septum (6) or an alar wing (6') between the optical supports. A green PPG component measuring green light transmission through the nasal septum includes a light source (20, 60) secured to the first optical support and a light detector (22, 62) secured to the second optical support. A red or near-infrared PPG component measuring red or near-infrared light transmission through the nasal septum includes a light source (30, 60) secured to one optical support and a light detector (32, 64) secured to the other optical support. An electronic data processor computes arterial blood oxygen saturation (SpO 2 ) from a ratio of intensities of the measured transmission of green light and the measured transmission of red or near-infrared light.
    • 在光学体积描记术(PPG)装置中,鼻架包括用鼻隔膜(6)或光学支架之间的翼片(6')固定到鼻部(1)的第一和第二光学支撑件(12,14)。 测量通过鼻中隔的绿光透射的绿色PPG部件包括固定到第一光学支架的光源(20,60)和固定到第二光学支架的光检测器(22,62)。 测量通过鼻中隔的红色或近红外光透射的红色或近红外PPG组件包括固定到一个光学支架的光源(30,60)和固定到另一光学支架的光检测器(32,64)。 电子数据处理器根据所测量的绿光透射率与测量的红光或近红外光透射率之比计算动脉血氧饱和度(SpO2)。
