275 results about "Thermoregulation" patented technology

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. For humans, this occurs when the body is exposed to constant temperatures of approximately 55 °C (131 °F), and with prolonged exposure (longer than a few hours) at this temperature and up to around 75 °C (167 °F) death is almost inevitable. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above 35 °C (95 °F) for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic control mechanisms of heat within the body malfunction, causing the body to lose heat faster than producing it. Normal body temperature is around 37 °C (99 °F), and hypothermia sets in when the core body temperature gets lower than 35 °C (95 °F). Usually caused by prolonged exposure to cold temperatures, hypothermia is usually treated by methods that attempt to raise the body temperature back to a normal range.

Method and apparatus for noninvasive physiologic monitoring

Intense environmental or working conditions can impede an individual's evaporative cooling mechanism normally responsible for thermoregulation during exercise or exertion. Non-invasive physiological monitoring capabilities are needed to more precisely define the cardiovascular responses and identify markers of impending failure of compensatory mechanisms prior to collapse or onset of irreversible pathology. The oxymetry method and system of the present invention provides non-invasive, continuous remote monitoring and analysis of cardiovascular and pulmonary function that overcomes accuracy and monitoring deficiencies of current oximetry systems.
