Following cold stress, waveforms and pressures are obtained: immediately after and five minutes after. Webbin addition to toe plethysmography, have been suggested by Wengi (31), but as far as is known they have not previously been reported. In general. pulse plethysmography permits a qualitative estimation of the circulation and both functional and organic changes are recorded (5, 11, 12, 17. 29). Consequently vasoconstriction.
