SYSTEM AND METHOD FOR ASSESSING CAPILLARY VITALITY
First Claim
1. A device for assessing capillary vitality comprising:
- an inflatable cuff;
a blood flow sensor in communication with the cuff;
a pressure sensor in communication with the cuff for reading pressure levels in the cuff;
a pressure instrument in fluid communication with the cuff for inflation and deflation thereof, the pressure instrument comprising;
a source of pressurized air; and
a conduit connected to the source of pressurized air and the cuff, thereby placing the source of pressurized air in fluid communication with the cuff;
at least one metabolic sensor for measuring a metabolic condition of a patient;
a microprocessor operably coupled to said pressure instrument and capable of controlling pressurized airflow to and from the cuff, wherein said microprocessor is arranged to receive inputs from the blood flow, pressure and metabolic sensors;
a computer program executable by the microprocessor such that when executed, the computer program causes the microprocessor to;
initiate an automatic inflation sequence resulting in a no flow condition;
initiate an automatic deflation sequence;
automatically qualify a perfusion measurement as an SPP value upon one or more conditions being met during the deflation sequence;
initiate the measurement of at least one metabolic factor through said at least one metabolic sensor,wherein the relationship among the blood flow, pressure and metabolic measurements are displayed.

Abstract
A device for assessing capillary vitality comprises an inflatable cuff, a blood flow sensor and a pressure sensor in communication with the cuff, a pressure instrument in fluid communication with the cuff for inflation and deflation thereof, a microprocessor coupled to the pressure instrument for controlling airflow, at least one metabolic sensor for measuring a metabolic condition, and a computer program executable by the microprocessor. The pressure instrument includes a source of pressurized air and a conduit connecting the source of pressurized air to the cuff. The microprocessor is arranged to receive inputs from the blood flow, pressure and metabolic sensors. When executed by the microprocessor, the computer program causes the microprocessor to initiate an automatic inflation sequence resulting in a no flow condition, initiate an automatic deflation sequence, automatically qualify a perfusion measurement as an SPP value upon one or more conditions being met during the deflation sequence, and initiate the measurement of at least one metabolic factor.
