Figure 3. Forearm blood flow and forearm vascular conductance responses to repeated bouts of contralateral ischaemic handgripping to fatigue after stellate ganglion block (protocol 1b).

Resting values were obtained prior to contralateral ischaemic handgrip. Handgrip values are from the last measurement prior to cessation of contralateral ischaemic handgripping. After stellate ganglion block there was a marked increase in forearm blood flow during handgripping. Mean arterial pressure is from trials these subjects completed during protocol 2. Data are expressed as means ±s.e.m.
