    • An improved pulse oximeter provides for simultaneous, noninvasive oxygen status and photoplethysmograph measurements at both single and multiple sites. In particular, this multiple-site, multiple-parameter pulse oximeter, or “stereo pulse oximeter” simultaneously measures both arterial and venous oxygen saturation at any specific site and generates a corresponding plethysmograph waveform. A corresponding computation of arterial minus venous oxygen saturation is particularly advantageous for oxygen therapy management. An active pulse-inducing mechanism having a scattering-limited drive generates a consistent pulsatile venous signal utilized for the venous blood measurements. The stereo pulse oximeter also measures arterial oxygen saturation and plethysmograph shape parameters across multiple sites. A corresponding calculation of delta arterial saturation and comparison of plethysmograph shape parameters between multiple sites is particularly advantageous for the detection and management of persistent pulmonary hypertension in neonates (PPHN), a patent ductus arteriosis (PDA), and aortic coarctation.
    • 改进的脉搏血氧饱和度计在单个和多个位置提供同时,无创的氧状态和光谱体积描记测量。 特别地,该多位点多参数脉搏血氧计或“立体声脉搏血氧计”同时测量任何特定部位的动脉和静脉血氧饱和度,并产生相应的体积描记器波形。 动脉负静脉血氧饱和度的相应计算对于氧疗治疗特别有利。 具有散射限制驱动的主动脉冲诱导机构产生用于静脉血液测量的一致的脉动静脉信号。 立体声脉搏血氧饱和度计还可测量多个部位的动脉血氧饱和度和体积描记图形状参数。 对于新生儿持续性肺动脉高压(PPHN),动脉导管未闭(PDA)和主动脉缩窄的检测和治疗,三位动脉饱和度的相应计算和多个位置之间体积描记图形状参数的比较特别有利。
