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.

A versatile, multi-port, intubation-permitting oxygen mask is provided including two diaphragms (nasal and oral) each configured with a continuous, flexible, modifiable membrane from which an instrument-access port may be manually constructed, when and if needed. The novel oxygen mask preferably includes a multiple-inlet port having a standard oxygen tube connector and an interchangeable breathing-therapy device connector, a carbon dioxide sampling port, an exhaust port, and a nose clip.
