Fig 1.
Example of different ZHF patch locations on the head of a euthanized pig.
The patch is located at position B (obliquely above the eye), circles indicate placement at location A (directly behind the temporal corner of the eye) and C (centered on the forehead).
Fig 2.
Pattern of mean temperatures during cooling (black) and maintaining phase (grey) at ZHF locations A (4 pigs), B (3 pigs) and C (4 pigs). Data points represent the mean temperature (TZHF or Tpulm) of the respective group for each time point (every 5 minutes). Number of paired measurements at ZHF location A: n = 130, at ZHF location B: n = 98, at ZHF location C: n = 135. Tpulm = blood temperature in the pulmonary artery; TZHF = temperature measured by the ZHF device.
Fig 3.
Bland Altman plots comparing Tpulm and TZHF for ZHF location A (4 pigs), B (3 pigs) and C (4 pigs) during cooling and maintaining phase. Tpulm = blood temperature in the pulmonary artery, TZHF = temperature measured by the ZHF device.
