Patient discussion about thermal

Q. What are the visual distinctions between thermal burns and frostbite? Is it possible to definitively distinguish the two from each other in all cases, or do they present identically in many cases? In other words, are frostbite injuries-for all intents and purposes, actual burns and if they are not, in what ways do they differ?

A. Early frostbite and minor burns may resemble one another visually (by whitened, blanched looking skin, and blister formation). However, last stage frostbite and thermal (heat) burns are very different.
In late stage frostbite, the ice crystals in the cells melt and the ruptured cells pour out their contents, then blisters may form. Since the affected area has basically lost circulation, gangrene sets in rather quickly and the tissue turns black and dry.
Deep (full thickness) heat related burns are surrounded by areas of erythema (reddened skin) and skin with less degrees of burning. Also, eschar is obviously charred skin tissue forming a scab like structure, and looks nothing like gangrene. The wound bed in a burn leaks plasma constantly. Blistering is pretty immediate with heat related burns of a sufficient degree.

Heat stress was recorded using an a thermal sensations rating scale ranging from "unbearably cold" (0.0) to "comfortable" (4.0) to "unbearably hot" (8.0), and was recorded every 30 minutes during each test (Tyler and Sunderland, 2011).
While they were seated and at rest, the subjects were informed that psychological reporting involves a thermally specific sense of thermal sensation and thermal comfort [9], that they would be asked to report an average sense during the period of exposure, and that intake and excretion of liquids were prohibited until the conclusion of the experiment.
indices, such as the predicted percentage of dissatisfied with local thermal comfort, thermal sensation and indoor air acceptability, are determined in terms of some measured parameter, such as dry bulb temperature, relative humidity and speed of air (ISO 7730, 2006).

According to Ali-Toudert and Mayer (2006), the structure (design) of a street is the key factor for studies on urban bioclimatology, which influences the internal and external micro-climates, and changes the thermal sensation of people and the energy consumption of buildings.
Presently, the non-linear behaviour of human's thermal sensation and the unavailability of a direct quantitative PMV regarding the inputs--output relations make it very difficult or impossible to design a direct control strategy of HVAC systems that regulate thermal comfort levels.
The subjective temperature is a kind of equivalent temperature proposed by McIntyre (1976) and this subjective temperature is an index near to a real thermal sensation when the equation is used depending on air velocity.
