Subjective evaluation of the warming method
injuries
The subjective evaluation of the heating methods yielded the following results (Table 
Subjective assessment of the heating methods halogen radiator and forced air warmerSome of the test persons found the temperature of the air at the outlet of the hose of the forced air warmer to be too hot (number not documented). Subsequent measurements of the temperatures of the outflowing air showed temperatures above 60 °C (maximum 70.5 °C). The test persons responded by pulling their feet away from the entry point of the hose under the plastic foil in good time. Thermal damage to the skin or other injuries were therefore not observed.
