Many operating room lights used halogen lamps [1] [2] or xenon lamps, [3] some with backup lamps that operated in case of lamp failure [4] until the advent of Light-emitting diodes as light sources since 2007 [5] which remove the problem of heat radiation and reduce energy requirements. [6]
Heat therapy, also called thermotherapy, is the use of heat in therapy, such as for pain relief and health. It can take the form of a hot cloth, hot water bottle, ultrasound, heating pad, hydrocollator packs, whirlpool baths, cordless FIR heat therapy wraps, and others. It can be beneficial to those with arthritis and stiff muscles and injuries ...
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections.
The treatment can also boost the rate of fluid removal along lymphatic tracks to decrease swelling, even treating lymphedema in breast cancer patients. And while it can help with the kind of ...
An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the emitter and cool ...
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. [1][2] Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. [3]
Hot cathode. A tungsten filament acting as a directly heated cathode in a low pressure mercury gas discharge lamp which emits electrons. To increase electron emission, a white thermionic emission mix coating is applied on hot cathodes, visible on the central portion of the coil. Typically made of a mixture of barium, strontium, and calcium ...
D014467. [edit on Wikidata] Ultraviolet light therapy or ultraviolet phototherapy is a treatment for psoriasis, atopic skin disorder, vitiligo and other skin diseases. There are two main treatments: UVB that is the most common, and PUVA. There are four UVB types of lamps: Fluorescnt Broad-Band UVB that emit 280-330 nanometer, Fluorescent Narrow ...
