Honolulu
Honolulu (; ) is the capital and largest city of the U.S. state of Hawaii, which is in the Pacific Ocean. It is an unincorporated county seat of the consolidated City and County of Honolulu, situated along the southeast coast of the island of Oahu, and is the westernmost and southernmost major U.S. city. Honolulu is Hawaii's main gateway to the world. It is also a major hub for business, finance, hospitality, and military defense in both the state and Oceania. The city is characterized by a mix of various Asian, Western, and Pacific cultures, reflected in its diverse demography, cuisine, and traditions. ''Honolulu'' means "sheltered harbor" or "calm port" in Hawaiian; its old name, ''Kou'', roughly encompasses the area from Nuuanu Avenue to Alakea Street and from Hotel Street to Queen Street, which is the heart of the present downtown district. The city's desirability as a port accounts for its historical growth and importance in the Hawaiian archipelago and the broader P ...

Supplemental Oxygen
Oxygen therapy, also known as supplemental oxygen, is the use of oxygen as medical treatment. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache. It may also be prophylactically given to maintain blood oxygen levels during the induction of anesthesia. Oxygen therapy is often useful in chronic hypoxemia caused by conditions such as severe COPD or cystic fibrosis. Oxygen can be delivered via nasal cannula or face mask, or via high pressure conditions such as in endotracheal intubation or hyperbaric chamber. It can also be given through bypassing the airway, such as in ECMO therapy. Oxygen is required for normal cellular metabolism. However, excessively high concentrations can result in oxygen toxicity, leading to lung damage and respiratory failure. Higher oxygen concentrations can also increase the risk of airway fires, particularly while smoking. Oxygen therapy can also dry out the nasal mucosa without humi ...

List Of People Who Died Climbing Mount Everest
At least 310 people have died attempting to reach the summit of Mount Everest which, at , is Earth's highest mountain and a particularly desirable peak for mountaineers. The most recent years without known deaths on the mountain are 1977, in which only two people reached the summit, and 2020, when permits were suspended by Nepal because of the COVID-19 pandemic in Nepal. Deaths have been attributed to avalanches, falls, serac collapse, exposure, frostbite, or health problems related to conditions on the mountain. Not all bodies have been located, so details on those deaths are not available. The upper reaches of the mountain are in the death zone, a mountaineering term for altitudes above a certain point – around , or less than of atmospheric pressure – where the oxygen pressure level is not sufficient to sustain human life. Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly (loss of vital functions) or indirectly ...

Green Boots
Green Boots is the name given to the unidentified body of a climber that became a landmark on the main Northeast ridge route of Mount Everest. The body has not been officially identified, but he is believed to be Tsewang Paljor, an Indian climber who died on Everest in 1996. The term ''Green Boots'' originated from the green Koflach mountaineering boots on his feet. All expeditions from the north side encountered the body curled in the limestone alcove cave at , until it was moved in 2014. History The first recorded video footage of Green Boots was filmed by British film-maker and climber Matt Dickinson in May, 1996. The footage can be viewed at minute mark 42:45 in "Summit Fever Brian Blessed Documentary" (1996). Over time, the corpse became known both as a landmark on the north route and for its association with the death of David Sharp. In 2014, Green Boots was moved to a less conspicuous location by members of a Chinese expedition. Possible identities Tsewang Paljor Gre ...

Cathy O'Dowd
Cathy O'Dowd (born 1968) is a South African rock climber, mountaineer, author and motivational speaker. She was the first woman to reach the summit of Mount Everest from both the south and the north sides on 25 May 1996 and 29 May 1999, respectively. O’Dowd grew up in Johannesburg, South Africa, and attended St. Andrew's School for Girls. She has climbed since her university days. When she was 21, she took part in her first mountain expedition, to the Ruwenzori in Central Africa. Everest expeditions Southeast ridge route Towards the end of 1995, O'Dowd was finishing a master's degree in Media Studies at Rhodes University when she applied for and got a place on the First South African Everest Expedition. On 11 May 1996, eight climbers died in a severe blizzard on their descent from the summit on the south side. This included a climbing guide and the leaders of two expeditions, American Scott Fischer and the New Zealander Rob Hall. O'Dowd was at the high camp just below the ...

Ian Woodall
Ian Woodall (born 17 August 1956) is a British mountain climber who has climbed Mount Everest several times. In 1996 Woodall was the leader of the controversial first South African Mount Everest expedition, during which one member of the party died. The expedition reached Camp IV – the last camp before the summit, and 923m below it – on 10 May, but were not directly involved in the disaster that unfolded that day. Following the tragedy the expedition returned to base camp and made a second attempt after a few days rest, achieving the summit on 28 May. Woodall reached the peak by 10 am, four other members of the expedition had done so by 11 am, but Bruce Herrod lagged behind and was the last to reach the peak; from there, at 5 pm, he spoke to the others by radio, but was never heard from again. The expedition was sponsored by Johannesburg newspaper '' The Sunday Times'', but its support of the expedition was later withdrawn. In late May 1998 Woodall togethe ...

Frostbite
Frostbite is a skin injury that occurs when exposed to extreme low temperatures, causing the freezing of the skin or other tissues, commonly affecting the fingers, toes, nose, ears, cheeks and chin areas. Most often, frostbite occurs in the hands and feet. The initial symptoms are typically a feeling of cold and tingling or numbing. This may be followed by clumsiness with a white or bluish color to the skin. Swelling or blistering may occur following treatment. Complications may include hypothermia or compartment syndrome. People who are exposed to low temperatures for prolonged periods, such as winter sports enthusiasts, military personnel, and homeless individuals, are at greatest risk. Other risk factors include drinking alcohol, smoking, mental health problems, certain medications, and prior injuries due to cold. The underlying mechanism involves injury from ice crystals and blood clots in small blood vessels following thawing. Diagnosis is based on symptoms. Severity m ...

Oxygen Deprivation
Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. Asphyxia causes generalized hypoxia, which affects primarily the tissues and organs. There are many circumstances that can induce asphyxia, all of which are characterized by the inability of a person to acquire sufficient oxygen through breathing for an extended period of time. Asphyxia can cause coma or death. In 2015, about 9.8 million cases of unintentional suffocation occurred which resulted in 35,600 deaths. The word asphyxia is from Ancient Greek "without" and , "squeeze" (throb of heart). Causes Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; env ...

Uzbeks
The Uzbeks ( uz, , , , ) are a Turkic ethnic group native to the wider Central Asian region, being among the largest Turkic ethnic group in the area. They comprise the majority population of Uzbekistan, next to Kazakh and Karakalpak minorities, and are also found as a minority group in: Afghanistan, Pakistan Tajikistan, Kyrgyzstan, Kazakhstan, Turkmenistan, Russia, and China. Uzbek diaspora communities also exist in Turkey, Saudi Arabia, United States, Ukraine, and other countries. Etymology The origin of the word ''Uzbek'' still remains disputed. One view holds that it is eponymously named after Oghuz Khagan, also known as ''Oghuz Beg'', became the word ''Uzbek''.A. H. Keane, A. Hingston Quiggin, A. C. Haddon, Man: Past and Present, p.312, Cambridge University Press, 2011, Google Books, quoted: "Who take their name from a mythical Uz-beg, Prince Uz (beg in Turki=a chief, or hereditary ruler)." Another theory states that the name means ''independent'', ''genuine man'', o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medication
A medication (also called medicament, medicine, pharmaceutical drug, medicinal drug or simply drug) is a drug used to diagnose, cure, treat, or prevent disease. Drug therapy ( pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drugs are classified in multiple ways. One of the key divisions is by level of control, which distinguishes prescription drugs (those that a pharmacist dispenses only on the order of a physician, physician assistant, or qualified nurse) from over-the-counter drugs (those that consumers can order for themselves). Another key distinction is between traditional small molecule drugs, usually derived from chemical synthesis, and biopharmaceuticals, which include recombinant proteins, vaccines, blood products used therapeutically (such as IVIG), gene therapy, monoclonal antibodies and cell therapy (for instance, stem cell th ...

Bottled Oxygen (climbing)
Bottled oxygen is oxygen in small, portable, high pressure storage cylinders, as used for high-altitude climbing. Bottled oxygen may also be for a breathing gas, especially for scuba diving or during surgery. (see also diving cylinder and oxygen tank) High-altitude climbing (mountaineering) usually requires the use of portable oxygen apparatus when climbing Mount Everest or the other eight-thousanders, though some mountaineers have ascended Everest without oxygen. The apparatus can be open-circuit (supplementary) or closed-circuit; the 1953 British Mount Everest expedition used both types. The death zone altitude is or above. 1920s and 1930s British expeditions all used open-circuit oxygen apparatus, as advocated by pioneer climbers George Finch, Noel Odell and Peter Lloyd. Open-circuit oxygen apparatus was trialled on the 1922 and 1924 British Everest expeditions; the bottled oxygen taken by the 1921 expedition was not used. The carrying frame used in 1922 and 1924 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
