Method and system for monitoring oxygenation levels of a compartment for detecting conditions of a compartment syndrome
First Claim
1. A method for automatically monitoring oxygenation levels of a compartment of a human body for automatically detecting conditions of a compartment syndrome, comprising:
- automatically monitoring oxygenation levels of the compartment of injured tissue in a continuous manner with a first sensor;
automatically monitoring oxygenation levels of healthy tissue in a continuous manner with a second sensor, the second sensor detecting systemic perfusion of the human body from the healthy tissue;
automatically monitoring blood pressure of the human body in a continuous manner, the blood pressure comprising diastolic and systolic blood pressure values;
displaying oxygenation levels of the compartment on a display device;
displaying diastolic and systolic blood pressure values simultaneously with the oxygenation levels of the compartment on the display device; and
activating an alarm when both the blood pressure of the human body comprising the diastolic and systolic blood pressure values decreases and oxygenation levels of the first sensor of the compartment start decreasing in value compared to the oxygenation levels of the second sensor for the healthy tissue.

Abstract
A method and system for continually monitoring oxygenation levels in real-time in compartments of an animal limb, such as in a human leg or a human thigh or a forearm, can be used to assist in the diagnosis of a compartment syndrome. The method and system can include one or more near infrared compartment sensors in which each sensor can be provided with a compartment alignment mechanism and a central scan depth marker so that each sensor may be precisely positioned over a compartment of a living organism. The method and system can include a device for displaying oxygenation levels corresponding to respective compartment sensors that are measuring oxygenation levels of a compartment of interest. The method and system can also monitor the relationship between blood pressure and oxygenation levels and activate alarms based on predetermined conditions relating to the oxygenation levels or blood pressure or both.
