Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract. An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation. Although oxygen stored in the blood and lungs can keep a person alive for several minutes after breathing stops, choking often leads to death.
A water balloon or water bomb is a balloon, often made of latex rubber, filled with water. Water balloons are used in a summer pastime of cooling off through water balloon fights. Water balloons are also popular for celebrations, including celebrating Holi and Carnival in India, Nepal, and several other countries.
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium, and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction.
Circular breathing is a breathing technique used by players of some wind instruments to produce a continuous tone without interruption. It is accomplished by inhaling through the nose while simultaneously pushing air out through the mouth using air stored in the cheeks.
A full-face diving mask is a type of diving mask that seals the whole of the diver's face from the water and contains a mouthpiece, demand valve or constant flow gas supply that provides the diver with breathing gas. The full face mask has several functions: it lets the diver see clearly underwater, it provides the diver's face with some protection from cold and polluted water and from stings, such as from jellyfish or coral. It increases breathing security and provides a space for equipment that lets the diver communicate with the surface support team.
A gag is a device used in sexual bondage and BDSM roleplay. Gags are usually associated with roleplays involving bondage, but that is not necessarily the case. The person who wears the gag is regarded as the submissive partner, while the other is regarded as the dominant one. People may wear gags for a variety of reasons. Some people derive erotic pleasure from a gag, either in a submissive or dominant role. When combined with other physical restraints, the wearing of a gag can increase the wearer's sense of helplessness and anxiety level within a BDSM scene by rendering them unable to speak during sexual activity, which some people enjoy.
Balloon modelling or balloon twisting is the shaping of special modelling balloons into various shapes, often balloon animals. People who create balloon animals and other twisted balloon decoration sculptures are called twisters, balloon benders, and balloon artists. Twisters often perform in restaurants, at birthday parties, fairs and at public and private events or functions.
In urology, a Foley catheter is one of many types of urinary catheters (UC). The Foley UC was named after Frederic Foley, who produced the original design in 1929. Foleys are indwelling UC, often referred to as an IDCs. This differs from in/out catheters. The UC is a flexible tube if it is indwelling and stays put, or rigid if it is in/out, that a clinician, or the client themselves, often in the case of in/out UC, passes it through the urethra and into the bladder to drain urine.
A balloon rocket is a rubber balloon filled with air or other gases. Besides being simple toys, balloon rockets are a widely used as a teaching device to demonstrate basic physics.
Porpoise is a tradename for scuba developed by Ted Eldred in Australia and made there from the late 1940s onwards. The first Porpoise was a closed circuit oxygen rebreather, and the following models were all single hose open circuit regulators.
Minimally invasive thoracic spinal fusion is one of the approaches to scoliosis surgery. Instead of a vertical scar down the back or horizontal from the middle of the chest to the center of the back, a rod is inserted through a series of small incisions on the side of the body. The spine is not exposed during the surgery; a small scope is used instead.
Lawrence “Larry” Charles Moss (born September 25, 1970) is an American artist, writer and educator who works mainly with latex balloons. He is known, in the field of large-scale balloon sculpture as art installation, for creating technically and aesthetically challenging sculptures which often incorporate literary, art and pop culture references.
Henry J. Maar (1921–1992), known as "The Sultan of Balloons", was one of the pioneers in balloon twisting. He appeared for over a decade on episodes of the long running Bozo's Circus. While the origins of balloon twisting is impossible to prove, Emmy Award winning producer/director Joseph Maar has provided evidence that his father, Henry, may be the founder of balloon twisting. Larry Moss calls Joseph Maar's evidence "compelling" but warns that if Joseph Maar is correct then the history of balloon twisting would have to be rewritten. For example, the 1975 book by "Jolly the Clown" Petri credits "Herman Bonnert from Pennsylvania at a magician's convention in 1939" as being the first balloontwister.
A balloon is a flexible membrane bag that can be inflated with a gas, such as helium, hydrogen, nitrous oxide, oxygen, or air. For special purposes, balloons can be filled with smoke, liquid water, granular media, or light sources. Modern day balloons are made from materials such as rubber, latex, polychloroprene, or a nylon fabric, and can come in many different colors. Some early balloons were made of dried animal bladders, such as the pig bladder. Some balloons are used for decorative purposes or entertaining purposes, while others are used for practical purposes such as meteorology, medical treatment, military defense, or transportation. A balloon's properties, including its low density and low cost, have led to a wide range of applications.
Foreign body aspiration occurs when a foreign body enters the airway which can cause difficulty breathing or choking. Objects may reach the respiratory tract and the digestive tract from the mouth and nose, but when an object enters the respiratory tract it is termed aspiration. The foreign body can then become lodged in the trachea or further down the respiratory tract such as in a bronchus. Regardless of the type of object, any aspiration can be a life-threatening situation and requires timely recognition and action to minimize risk of complications. While advances have been made in management of this condition leading to significantly improved clinical outcomes, there were still 2,700 deaths resulting from foreign body aspiration in 2018. Approximately one child dies every five days due to choking on food in the United States, highlighting the need for improvements in education and prevention.
Basic airway management is a concept and set of medical procedures performed to prevent and treat airway obstruction and allow for adequate ventilation to a patient's lungs. This is accomplished by clearing or preventing obstructions of airways. Airway obstructions can occur in both conscious and unconscious individuals. They can also be partial or complete. Airway obstruction is commonly caused by the tongue, the airways itself, foreign bodies or materials from the body itself, such as blood or vomit. Contrary to advanced airway management, basic airway management technique do not rely on the use of invasive medical equipment and can be performed with less training. Medical equipment commonly used includes oropharyngeal airway, nasopharyngeal airway, bag valve mask, and pocket mask. Airway management is a primary consideration in cardiopulmonary resuscitation, anaesthesia, emergency medicine, intensive care medicine and first aid.
The term kamifūsen refers to several types of paper balloons in Japanese culture. They are simple toys for children, advertising give-aways for traditional medicine companies, and illuminated flying balloons at festivals.
The mechanism of diving regulators is the arrangement of components and function of gas pressure regulators used in the systems which supply breathing gases for underwater diving. Both free-flow and demand regulators use mechanical feedback of the downstream pressure to control the opening of a valve which controls gas flow from the upstream, high-pressure side, to the downstream, low-pressure side of each stage. Flow capacity must be sufficient to allow the downstream pressure to be maintained at maximum demand, and sensitivity must be appropriate to deliver maximum required flow rate with a small variation in downstream pressure, and for a large variation in supply pressure, without instability of flow. Open circuit scuba regulators must also deliver against a variable ambient pressure. They must be robust and reliable, as they are life-support equipment which must function in the relatively hostile seawater environment, and the human interface must be comfortable over periods of several hours.
