Tissue temperature beneath the epidermis of the back of the ear following a 1 second application of the vapocoolant spray from 10 cm to dead tissue. The area beneath the dotted line represents the period of time during which the tissue was at an adequate temperature to inhibit nociception (<10 °C).
