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.
