Flushing with saline should be painless if the cannula is in its proper place, although if the saline is not warmed there may be a cold sensation running up the vein. A painful flush may indicate tissuing or phlebitis and is an indication that the cannula should be relocated. [1] Solutions other than normal saline may be used.
Sensor operated plumbing fixtures have fewer moving parts, and therefore outlast traditional manual flush fixtures. Additionally, they reduce water consumption by way of intelligent flushing schedules (fuzzy logic) that determines the quantity of each flush based on how many people are standing in line to use the fixture.
Diaphragm valves can be controlled by various types of actuators e.g. manual, pneumatic, hydraulic, electric etc. The most common diaphragm valves use pneumatic actuators ; in this type of valve, air pressure is applied through a pilot valve into the actuator which in turn raises the diaphragm and opens the valve.
Old water pipe, remnant of the Machine de Marly near Versailles, France. Lead was the favoured material for water pipes for many centuries because its malleability made it practical to work into the desired shape. Such use was so common that the word "plumbing" derives from plumbum, the Latin word for lead.
Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
