administering medical gases; regulators, flowmeter, and controlling devices

TermDefinition
preset regulators a device that decreases the pressure from a gas supply system to a determined lower pressure
single- stage regulator a pressure reducing system that lowers primary equipment pressure to working pressure (appr. 50 PSIG) in one step.
adjustable, multiple- orifice flow restrictor uses a series of calibrated openings in a disk that can be adjusted to deliver different flows.
adjustable regulators a valve that allows the user to determine (adjust) pressure limits
Boothby-Lovelace-Bulbulian (BLB) mask an apparatus for administering oxygen; consists of a mask fitted with an inspiratory expiratory valves and a rebreathing bag
carbogen carbon dioxide and oxygen mixture
driving pressure the amount of pressure required to move a fluid through a tube. to maintain a given level of fluid flow through a tube, the driving pressure will increase in proportion to the resistance offered by the tube
fixed orifice flow restrictors the operating pressure is curial to the accuracy of the device
flow restrictors a device that reduced the flow of a fluid/gas out of a system by providing an instream obstruction usually in the form of a orifice of reduced size thus causing back pressure in the system.
heliox low density therapeutic mixture of helium with at least 20% oxygen used in some institution as part of large airway obstruction treatment
high flow fixed performance oxygen delivery system oxygen therapy equipment that supplies inspired gas at a consistent present oxygen concentration also called high flow systems
low-flow variable performance oxygen delivery system oxygen therapy equipment that delivers oxygen at a flow that provides only part of the patients inspired gas needs also called low flow system
monoplace hyperbaric chamber a hyperbaric unit rated for single occupancy
multiplace hyperbaric chamber a walk-in hyperbaric unit that provides enough space to treat two or more patients simultaneously
multistage regulators a pressure reducing valve that has more than one level of pressure reduction between system pressure and working pressure
mustache cannula a type of reservoir nasal cannula that can reduce oxygen supply use from that of a continuous-flow nasal cannula
non-pressure compensated the needle valve is located before the indicator tube. restriction or high resistance devices attached to the outlet of a non pressure compensated Thorpe tube flowmeter create back pressure, which is transmitted back to the needle valve.
oxygen adder simplest example of a oxygen proportioner system consists of two flowmeters, one attached to an oxygen supply and the other attached to an air supply
oxygen blender a devices that mixes oxygen with air or other gases to provide a precise oxygen concentration
pendant cannula a type of reservoir nasal cannula that can reduce oxygen supply use. the reservoir is attached as connecting tubing that is a conduit to a pendant which hangs below the chin.
pressure compensated the most commonly used flowmeters in respiratory care they provide accurate estimates of flow regardless of the downstream pressure
pulse demand oxygen delivery system a system that delivers oxygen to the patient only during inspiration
Thorpe tube flowmeters a type of flowmeter in which the has stream suspends a steel ball in a tapered tube. as the ball obstructs a greater proportion of the cross section of the tapered tube flow is reduced
