Rhys-Davies exsanguinator: pressure characteristics and technique for improving performance

This paper reports the results of an investigation into the pressure exerted by the Rhys-Davies exsanguinator on the palm and dorsum of the hand. We hypothesised that, due to the shape of the hand, the palm is shielded from the full effect of the exsanguinator, but our study showed that it is compressed as well as the dorsum. However, placing a bag of fluid in the patient's palm significantly increased the pressure applied to the palm.
