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.

Five questions aimed at recording instantaneous thermal comfort, thermal sensation, airflow preference, temperature preference, and thermal environment acceptability responses of the subjects.
PMV and PPD indices were calculated by the software, using the same seven points thermal sensation PMV scale defined in EN ISO 7730 standard (EN ISO 7730:2005).
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 thermal sensation votes, occupants prefer warm, thermally neutral, and slightly cool air movement.
2011) noted that changes in temperature are not a requirement for the initiation of thermoregulatory behaviour in humans and that thermal sensation and thermal discomfort are capable behavioral controllers.
To overcome this problem, the thermal sensation index should be calculated as an implicit result of the six previously mentioned variables influencing human's thermal sensation.

There are a good correlation between mean skin temperature and the thermal sensation and thermal comfort of a human body.
Thermal comfort can be estimated by a predicted mean vote (PMV) index introduced by Fanger (1972), which is an index to predict the mean value of votes of a large group of people on the seven-point thermal sensation scale ranging from -3 (very cold) to +3 (very hot).
In general, the potential for occupants to adapt psychologically or behaviorally to the thermal environments in the field seems to weaken the prospect that there is a clear-cut relationship between certain categories of thermal satisfaction and certain ratings of thermal sensation.
The workers were asked to fill out at least one self-administered questionnaire inquiring thermal sensation, ventilation and whether they felt air movement, and if yes, whether the air movement felt uncomfortable.
