Altitude Sickness
Altitude sickness, the mildest form being acute mountain sickness (AMS), is the harmful effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. Acute mountain sickness can progress to high-altitude pulmonary edema (HAPE) with associated shortness of breath or high-altitude cerebral edema (HACE) with associated confusion. Chronic mountain sickness may occur after long-term exposure to high altitude. Altitude sickness typically occurs only above , though some are affected at lower altitudes. Risk factors include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation. Diagnosis is based on symptoms and is supported in those who have more than a minor reduction in activities. It is recommended that at high altitude any symptoms of headache, nausea ...

Indian Army
The Indian Army is the land-based branch and the largest component of the Indian Armed Forces. The President of India is the Supreme Commander of the Indian Army, and its professional head is the Chief of Army Staff (COAS), who is a four-star general. Two officers have been conferred with the rank of field marshal, a five-star rank, which is a ceremonial position of great honour. The Indian Army was formed in 1895 alongside the long established presidency armies of the East India Company, which too were absorbed into it in 1903. The princely states had their own armies, which were merged into the national army after independence. The units and regiments of the Indian Army have diverse histories and have participated in several battles and campaigns around the world, earning many battle and theatre honours before and after Independence. The primary mission of the Indian Army is to ensure national security and national unity, to defend the nation from external aggression an ...

Ibuprofen
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used for treating pain, fever, and inflammation. This includes painful menstrual periods, migraines, and rheumatoid arthritis. It may also be used to close a patent ductus arteriosus in a premature baby. It can be used by mouth or intravenously. It typically begins working within an hour. Common side effects include heartburn and a rash. Compared to other NSAIDs, it may have other side effects such as gastrointestinal bleeding. It increases the risk of heart failure, kidney failure, and liver failure. At low doses, it does not appear to increase the risk of heart attack; however, at higher doses it may. Ibuprofen can also worsen asthma. While whether it is safe in early pregnancy is unclear, it appears to be harmful in later pregnancy, so is not recommended. Like other NSAIDs, it works by inhibiting the production of prostaglandins by decreasing the activity of the enzyme cyclooxygenase (COX). Ibuprofen ...

Peripheral Edema Of A Woman's Face, Before And After; Annapurna Base Camp, 2015
A peripheral or peripheral device is an auxiliary device used to put information into and get information out of a computer. The term ''peripheral device'' refers to all hardware components that are attached to a computer and are controlled by the computer system, but they are not the core components of the computer, such as the CPU or power supply unit. In other words, peripherals can also be defined as devices that can be easily removed and plugged into a computer system. Several categories of peripheral devices may be identified, based on their relationship with the computer: *An ''input device'' sends data or instructions to the computer, such as a mouse, keyboard, graphics tablet, image scanner, barcode reader, game controller, light pen, light gun, microphone and webcam; *An '' output device'' provides output data from the computer, such as a computer monitor, projector, printer, headphones and computer speaker; *An ''input/output device'' performs both input and outp ...

Kilik Pass
The Kilik Pass (elevation ; ; ur, کلوک پاس) to the west of Mintaka Pass is a high mountain pass in the Karakorum Mountains between Gilgit-Baltistan in Pakistan and Xinjiang in China. The two passes were, in ancient times, the two main access points into the Upper Hunza Valley (also called Gojal Valley) from the north. In addition, the two passes were also the paths used to reach Chalachigu Valley and Taghdumbash Pamir from the south. History During ancient times, Mintaka Pass and Kilik Pass were the shortest and quickest way into northern India from the Tarim Basin, and one that was usually open all year, but was extremely dangerous and only suited for travellers on foot. From Tashkurgan one travelled just over south to the junction of the Minteke River, modern day Chalachigu River. Heading some west up this valley one reached the Mintaka Pass, (and further, the alternative Kilik Pass), which both led into upper Hunza from where one could travel over the infamo ...

Karakoram Mountains
The Karakoram is a mountain range in Kashmir region spanning the borders of Pakistan, China, and India, with the northwest extremity of the range extending to Afghanistan and Tajikistan. Most of the Karakoram mountain range falls under the jurisdiction of Gilgit-Baltistan, which is controlled by Pakistan. Its highest peak (and world's second-highest), K2, is located in Gilgit-Baltistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, and extends into Ladakh (controlled by India) and Aksai Chin (controlled by China). It is the second-highest mountain range in the world and part of the complex of ranges including the Pamir Mountains, the Hindu Kush and the Himalayan Mountains. The Karakoram has eighteen summits over in height, with four exceeding : K2, the second-highest peak in the world at , Gasherbrum I, Broad Peak and Gasherbrum II. The range is about in length and is the most heavily glaciated part of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Hyperbaric Bag
A portable hyperbaric bag, of which one brand is the Gamow () bag, is an inflatable pressure bag large enough to accommodate a person. The patient can be placed inside the bag, which is then sealed and inflated with a foot pump. Within minutes, the effective altitude can be decreased by 1000 m to as much as 3000 m (3281 to 9743 feet) depending on the elevation. The bag is pressurised to ; the pressure gradient is regulated by pop-off valves set to the target pressure. History The Gamow bag was named after its inventor, Igor Gamow, son of George Gamow. Igor Gamow originally designed a predecessor to the Gamow bag called "The Bubble" to study the effect of high altitude on stamina and performance in athletes. Gamow later re-designed "The Bubble" into a bag that could be used in high-altitude wilderness. Application It is primarily used for treating severe cases of altitude sickness, Gov't Doc # USARIEM-TN94-2. high-altitude cerebral edema, and high-altitude pulmonary ...

Chronic Mountain Sickness
Chronic mountain sickness (CMS) is a disease in which the proportion of blood volume that is occupied by red blood cells increases (polycythaemia) and there is an abnormally low level of oxygen in the blood (hypoxemia). CMS typically develops after extended time living at high altitude (over ). It is most common amongst native populations of high altitude nations. The most frequent symptoms of CMS are headache, dizziness, tinnitus, breathlessness, palpitations, sleep disturbance, fatigue, loss of appetite, confusion, cyanosis, and dilation of veins. CMS was first described in 1925 by Carlos Monge Medrano, a Peruvian doctor who specialised in diseases of high altitude. While acute mountain sickness is experienced shortly after ascent to high altitude, chronic mountain sickness may develop only after many years of living at high altitude. In medicine, high altitude is defined as over , but most cases of CMS occur at over . It has recently been correlated with increased expression of ...

Shortness Of Breath
Shortness of breath (SOB), also medically known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct sensations, the degree of distress and discomfort involved, and its burden or impact on the patient's activities of daily living. Distinct sensations include effort/work to breathe, chest tightness or pain, and "air hunger" (the feeling of not enough oxygen). The tripod position is often assumed to be a sign. Dyspnea is a normal symptom of heavy physical exertion but becomes pathological if it occurs in unexpected situations, when resting or during light exertion. In 85% of cases it is due to asthma, pneumonia, cardiac ischemia, interstitial lung disease, congestive heart fail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headache
Headache is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. There is an increased risk of depression in those with severe headaches. Headaches can occur as a result of many conditions. There are a number of different classification systems for headaches. The most well-recognized is that of the International Headache Society, which classifies it into more than 150 types of primary and secondary headaches. Causes of headaches may include dehydration; fatigue; sleep deprivation; stress; the effects of medications (overuse) and recreational drugs, including withdrawal; viral infections; loud noises; head injury; rapid ingestion of a very cold food or beverage; and dental or sinus issues (such as sinusitis). Treatment of a headache depends on the underlying cause, but commonly involves pain medication (especially in case of migraine or cluster headache). A headache is one of the most commonly experienc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Of High Altitude On Humans
The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around above sea level, the saturation of oxyhemoglobin begins to decrease rapidly. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above as the death zone, where it is generally believed that no human body can acclimatize. At extreme altitudes, the ambient pressure can drop below the vapor pressure of water at body temperature, but at such altitudes even pure oxygen at ambient pressure cannot support human life, and a pressure suit is necessary. A rapid depressurisation to the low pressures of high altitudes can trigger altitude decompression sickness. Effects as a functi ...
