title: Automated temperature control system for vagal cooling.
abstract: An automated cooling system for vagal cold blockade was developed. A simple electronic circuit is described that enabled regulation of the steady-state nerve or circulant temperature to within +/- 0.1 degree C by alternating the cold circulant between low and high flows (10 and 350 ml/min, respectively). The 90% rise time ranged from 15 to 40 s depending on the desired steady state and the surrounding temperatures. The present apparatus can be conveniently and safely used, especially for differential vagal cold blockade.
