A liquid cooling garment (LCG) is a form-fitting garment that is used to remove body heat from the wearer. It is commonly used in environments where evaporative cooling from sweating and open-air convection cooling does not work or is insufficient, or when the wearer has a biological problem that hinders self-regulation of body temperature.
It is intended to reduce rapidly the person's temperature to below 34 °C (93 °F) while targeting the brain as the first area of cooling. Research into the device has shown cooling rates of 2.6 °C (4.7 °F) per hour in the brain (measured through infrared tympanic measurement) and 1.6 °C (2.9 °F) per hour for core body temperature reduction.
The Arctic Sun Temperature Management System is a non-invasive targeted temperature management system. It modulates patient temperature by circulating chilled water in pads directly adhered to the patient's skin. Using varying water temperatures and a computer algorithm, a patient's body temperature can be better controlled.
A hypothermia cap (also referred to as cold cap or cooling cap) is a therapeutic device used to cool the human scalp.Its most prominent medical applications are in preventing or reducing alopecia in chemotherapy, and for preventing cerebral palsy in babies born with neonatal encephalopathy caused by hypoxic-ischemic encephalopathy (HIE).
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
PDRCs can aid systems that are more efficient at lower temperatures, such as photovoltaic systems, [15] [25] dew collection devices, and thermoelectric generators. [ 15 ] [ 25 ] Passive radiative cooling technologies use the infrared window of 8–13 μm to radiate heat into outer space and impede solar absorption.
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Hospitals and emergency medical services commonly use surface cooling systems that circulate cold air or water around blankets or pads. Advantages of this method are accuracy of cooling due to auto-regulating temperature control, feedback probes, applicable in non-hospital settings, and non-complexity of use. [8]
