Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema , hyperpigmentation , scaling, and telangiectasias in the affected ...
In-water recompression (IWR) or underwater oxygen treatment is the emergency treatment of decompression sickness by returning the diver underwater to help the gas bubbles in the tissues, which are causing the symptoms, to resolve.
Prior to convulsion, several symptoms may be present – most distinctly that of an aura. During 1942 and 1943, Professor Kenneth W Donald, working at the Admiralty Experimental Diving Unit, carried out over 2,000 experiments on divers to examine the effects of oxygen toxicity. To date, no comparable series of studies has been performed.
A heating pad is a pad used for warming of parts of the body in order to manage pain. Localized application of heat causes the blood vessels in that area to dilate, enhancing perfusion to the targeted tissue. Types of heating pads include electrical, chemical and hot water bottles. Specialized heating pads (mats) are also used in other settings.
The prevalence of PAD in the general population is 3–7%, affecting up to 20% of those over 70; [85] 70%–80% of affected individuals are asymptomatic; only a minority ever require revascularization or amputation. [citation needed] Peripheral artery disease affects one in three diabetics over the age of 50. In the US, it affects 12–20 ...
In natural gas furnaces, water heaters, and room heating systems, a safety cut-off switch is normally included so that the gas supply to the pilot and heating system is shut off by an electrically operated valve if the pilot light goes out. This cut-off switch usually detects the pilot light in one of several ways: A flame rectification device. [2]
The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). ). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery dise
Head-up display (HUDs) reduce the necessity of the pilot having to focus on the far runway and near instruments. The accommodation process is no longer needed, optimal in diminishing the onset of fatigue. Blinking lights on aircraft avionics are extremely effective at capturing a pilot's attention, however, they contribute to fatigue.
