US 9,314,165 B2 · Method and system for monitoring oxygenation levels of compartments and 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 may comprise hardware or software (or both) may adjust one or more algorithms based on whether tissue being monitored was traumatized or is healthy. 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.

Dependent claims

A method for automatically monitoring oxygenation levels of a compartment of a human body for automatically detecting conditions of a compartment syndrome with a computing device, comprising:

automatically monitoring oxygenation levels of the compartment in a continuous manner with the computing device coupled to a non-invasive compartment sensor;
automatically monitoring oxygenation levels of healthy tissue with the computing device coupled to a non-invasive healthy tissue sensor in a continuous manner, the non-invasive healthy tissue sensor detecting systemic perfusion of the human body from the healthy tissue;
automatically monitoring blood pressure of the human body in a continuous manner with the computing device coupled to a non-invasive blood pressure device, the blood pressure comprising diastolic and systolic blood pressure values;
and
activating an alarm module with the computing device when both the blood pressure of the human body comprising the diastolic and systolic blood pressure values decreases and oxygenation levels of the non-invasive compartment sensor start decreasing in value compared to the oxygenation levels of the non-invasive healthy tissue sensor for the healthy tissue.
