Total body heat, bedside shivering-assessment scale and subjective perception of cold

HEAT, COLD
The calculated parameter total body heat was significantly higher when using forced air warming compared to halogen floodlight warming shortly after warming was initiated (Fig. Shivering was observed in three volunteers. In two volunteers, shivering only occurred during the halogen floodlight test. In one volunteer, shivering was observed during both - the halogen floodlight and the forced air warming test - but the shivering disappeared during the forced air warming test.As a subjective parameter, the cold perception of each participant was assessed via NRS at each point in time during the trial. The participants felt less cold while being warmed with the forced air warming compared to being warmed by halogen floodlights. These differences were significant (Fig.
