Figure 2. Forearm blood flow (FBF) and estimated forearm vascular conductance (FVC) responses to contralateral ischaemic handgripping to fatigue prior to stellate ganglion block (protocol 1a).

Resting values were obtained prior to contralateral ischaemic handgrip. Handgrip values are from the last measurement prior to cessation of contralateral ischaemic handgripping. Mean arterial pressure (MAP) values are from trials these subjects completed during protocol 2. Data are expressed as means ±s.e.m.
