HYPERSATURATION INDEX

摘要

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.

主权项

1. A method of measuring a quantity of oxygen dissolved in blood of a patient, the method comprising:
emitting light of at least a first and second wavelength of light from a light emitter into a portion of a body of the patient; detecting the light after attenuation of the body, wherein the detected attenuation of the light is indicative of a physiological condition of the body of the patient; using the detected measures of the attenuations of the first and second wavelengths of light to determine a measure of a quantity of oxygen dissolved in the blood of a patient, where the measure indicates increasing dissolved oxygen in the blood above a 100% oxygen saturation condition of the patient; and displaying, using a displayed measurement separate from any oxygen saturation measurements, an indication the measure of the quantity of oxygen dissolved in the blood of the patient.
