Abstract: Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.

Abstract translation: 本公开的实施例提供了用于在患者达到100％氧饱和度之后测量患者对血流中的氧吸收的过饱和指数。 该过饱和指数提供了患者氧气分压的指示。 在本发明的一个实施方案中，基于测量点处两种不同波长能量的吸收比计算过饱和指数。 在本发明的实施例中，确定最大过饱和指数阈值，使得当过饱和指数达到或超过阈值时触发警报。 在另一个实施例中，当过饱和指数首次计算时达到或低于其起始点时，触发报警。
