- Fig 1.
Temperature recordings from 9 sheep (mean ΔT and 95% CI, plotted at 5-minute intervals) that were measured during (0–180 minutes) and after (180–210 minutes) selective intracarotid blood cooling in the frontal and temporal cortical probes of the cooled-versus-noncooled hemisphere (A) and cooled-versus–central venous temperature (B), respectively.
- Fig 2.
Mean temperature gradients (averaged over 8 sheep) among the cooled hemisphere and the central venous temperature, noncooled hemisphere, and nasal temperature, respectively, during 180 minutes of cooling and 30 minutes of rewarming (time-averaged at 5-minute intervals).
- Fig 3.
Microprobe temperature measurements performed at 30-minute intervals during the cooling phase at predefined distances to the cooling catheter tip (1, 5, and 10 cm) in comparison with continuously recorded ipsilateral brain cortex and central venous (IVC) temperatures.
