hyperbaric medicine is medical treatment in which an ambient pressure greater than sea level atmospheric pressure is a necessary component. the treatment comprises hyperbaric oxygen therapy hbot , the medical use of oxygen at an ambient pressure higher than atmospheric pressure, and therapeutic recompression for decompression illness, intended to reduce the injurious effects of systemic gas .
disconnecting or making safe the equipment involves the removal of all energy sources and is known as isolation.the steps necessary to isolate equipment are often documented in an isolation procedure or a lockout tagout procedure.the isolation procedure generally includes the following tasks: citation needed announce shut off
a thermocline also known as the thermal layer or the metalimnion in lakes is a thin but distinct layer in a large body of fluid e.g. water, as in an ocean or lake; or air, e.g. an atmosphere in which temperature changes more rapidly with depth than it does in the layers above or below. in the ocean, the thermocline divides the upper mixed layer from the calm deep water below.
demand valve oxygen therapy dvot is a way of delivering high flow oxygen therapy using a device that only delivers oxygen when the patient breathes in and shuts off when they breathe out. dvot is commonly used to treat conditions such as cluster headache, which affects up to four in 1000 people 0.4% , and is a recommended first aid procedure for several diving disorders.
a diving regulator has one or two 7/16' unf high pressure ports upstream of all pressure-reducing valves to monitor the gas pressure remaining in the diving cylinder, provided that the valve is open. there are several types of contents gauge. standard submersible pressure gauge
the buoyancy compensator is operated by adjusting the volume of gas contained in the bladder, using an inflation valve to inject gas and one or more deflation valves, or dump valves to release gas, which is usually supplied directly from a breathing gas cylinder, or orally, as exhaled gas, though dedicated gas cylinders can be used. at the .
the halcyon rb80 is a non-depth-compensated passive addition semi-closed circuit rebreather of similar external dimensions to a standard al80 scuba cylinder 11-litre, 207-bar aluminium cylinder, 185 mm diameter and about 660 mm long . it was originally developed by reinhard buchaly rb in 1996 for the cave exploration dives conducted by the european karst plain project ekpp .
the cdlse clearance divers' life support equipment is made by divex in aberdeen, scotland. it is an electronic closed circuit rebreather designed to be silent and non-magnetic.it allows diving to 60 metres 200 ft using air as diluent, or up to 120 metres 390 ft using heliox and trimix.. some sources describe it as a 'stealth clearance divers life support equipment'.
a rupture disk, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.. a rupture disk is a type of sacrificial part because it has a one-time-use membrane that fails at a .
the dive/surface valve dsv is a valve on the mouthpiece which can switch between the loop and ambient surroundings. it is used to close the loop at the surface to allow the diver to breathe atmospheric air, and may also be used underwater to isolate the loop so that it will not flood if the mouthpiece is taken out of the mouth. bailout valve
history. in 2002, divers brian armstrong, gene hobbs, and james wagner formed the first board of directors for the rubicon foundation.. rubicon research repository. the rubicon research repository rrr is the foundation's premier project that started in 2006. the rrr is an online database of environmental physiology reports, including both hyperbaric and hypobaric medicine, as well as other .
a butterfly valve is a valve that isolates or regulates the flow of a fluid. the closing mechanism is a disk that rotates. 1 principle of operation. 2.1 wafer-style butterfly valve. 2.2 lug-style butterfly valve. 2.3 rotary valve. 3 use in industry. principle of operation. operation is similar to that of a ball valve, which allows for quick .
