Figure 1

Example of transcutaneous recordings during a 300 second tourniquet cuff occlusion (initiated at 300 s and finished at 600 s) obtained in the upper extremity at arm level illustrating the sequential events detected in the variables tcpO₂, tcpCO₂ and LDF. Gender related differences, as reported in the literature for the transcutaneous gases are apparent. However, striking differences are consistently found for the LDF measurements obtained under the present experimental conditions (see text)
