Jean Hilliard’s heart did not fibrillate.

The Temperature Measurements And What They Mean

The specific temperature readings in Jean Hilliard’s case are reported inconsistently across different sources, and this inconsistency is worth examining directly rather than papering over.

Some sources report her core temperature on arrival at the hospital as approximately 27 degrees Celsius (80.6 degrees Fahrenheit).

Others describe it as below the measurable range of standard hospital thermometers, which would place it below approximately 88 degrees Fahrenheit (or about 31 degrees Celsius in some formulations).
