AI Technical Summary
Existing methods for monitoring autoregulation in mammals are inaccurate due to confounding factors that affect tissue oxygenation parameters independently of autoregulation function, such as blood carbon dioxide levels and extracerebral blood flow, leading to unreliable determination of autoregulation states.
A method and apparatus using a tissue oximeter and blood pressure sensing device to continuously monitor tissue oxygenation parameters and blood pressure, identifying and accounting for confounding factors to determine an accurate autoregulation function state by analyzing tissue oxygenation parameter and blood pressure trends.
Enables precise determination of autoregulation function states by filtering out confounding factors, allowing for the identification of lower and upper limits of autoregulation, thereby improving the accuracy of autoregulation monitoring.
