Basic concepts of fluid and electrolyte

Diagnosing electrolyte disorders A simple blood test can measure the levels of electrolytes in your body. A blood test that looks at your kidney function is important as well. Your doctor may want to perform a physical exam or order extra tests to confirm a suspected electrolyte disorder.

Basic concepts of fluid and electrolyte

Gas[ edit ] Gases are compressible and change volume when placed under pressure, are heated or are cooled. A volume of gas under one set of pressure and temperature conditions is not equivalent to the same gas under different conditions. Liquid[ edit ] For liquids, various units are used depending upon the application and industry, but might include gallons U.

Mechanical flow meters[ edit ] A positive displacement meter may be compared to a bucket and a stopwatch. The stopwatch is started when the flow starts, and stopped when the bucket reaches its limit.

The volume divided by the time gives the flow rate. For continuous measurements, we need a system of continually filling and emptying buckets to divide the flow without letting it out of the pipe.

These continuously forming and collapsing volumetric displacements may take the form of pistons reciprocating in cylinders, gear teeth mating against the internal wall of a meter or through a progressive cavity created by rotating oval gears or a helical screw.

The piston meter operates on the principle of a piston rotating within a chamber of known volume. For each rotation, an amount of water passes through the piston chamber. Through a gear mechanism and, sometimes, a magnetic drive, a needle dial and odometer type display are advanced.

Oval gear meter[ edit ] A positive displacement flowmeter of the oval gear type. Fluid forces the meshed gears to rotate; each rotation corresponds to a fixed volume of fluid. Counting the revolutions totalizes volume, and the rate is proportional to flow. An oval gear meter is a positive displacement meter that uses two or more oblong gears configured to rotate at right angles to one another, forming a T shape.

Such a meter has two sides, which can be called A and B. No fluid passes through the center of the meter, where the teeth of the two gears always mesh. On one side of the meter Athe teeth of the gears close off the fluid flow because the elongated gear on side A is protruding into the measurement chamber, while on the other side of the meter Ba cavity holds a fixed volume of fluid in a measurement chamber.

As the fluid pushes the gears, it rotates them, allowing the fluid in the measurement chamber on side B to be released into the outlet port. Meanwhile, fluid entering the inlet port will be driven into the measurement chamber of side A, which is now open.

The teeth on side B will now close off the fluid from entering side B.

Making your own electrolyte powder is a low cost alternative to purchasing those expensive sports drinks. An added bonus to making your own electrolyte powder is it gives you complete control over the ingredients of the electrolyte drink and you can have it on hand when you need it the most. Making connections - understand the concept of a diuretic and its impact on a person's fluid and electrolyte balance Additional Learning Paired with this quiz and worksheet is a lesson called. Bases react with acids to neutralize each other at a fast rate both in water and in alcohol. When dissolved in water, the strong base sodium hydroxide ionizes into hydroxide and sodium ions. NaOH → Na + + OH − and similarly, in water the acid hydrogen chloride forms hydronium and chloride ions. HCl + H 2 O → H 3 O + + Cl − When the two .

This cycle continues as the gears rotate and fluid is metered through alternating measurement chambers. Permanent magnets in the rotating gears can transmit a signal to an electric reed switch or current transducer for flow measurement.

Though claims for high performance are made, they are generally not as precise as the sliding vane design.

The outlet port is located in the area where the gears are coming back together. The fluid is forced out of the meter as the gear teeth mesh and reduce the available pockets to nearly zero volume.

Sorry! Something went wrong! Fluid and Electrolyte Balance The kidneys are essential for regulating the volume and composition of bodily fluids. This page outlines key regulatory systems involving the kidneys for controlling volume, sodium and potassium concentrations, and the pH of bodily fluids.

There are two or three main objectives for people who create automotive devices — increasing the mpg performance and reducing the harmful emissions are the top two priorities, while running the vehicle on water alone is the aim of a few people.

Helical gear[ edit ] Helical gear flow meters get their name from the shape of their gears or rotors. These rotors resemble the shape of a helix, which is a spiral-shaped structure. As the fluid flows through the meter, it enters the compartments in the rotors, causing the rotors to rotate.

The length of the rotor is sufficient that the inlet and outlet are always separated from each other thus blocking a free flow of liquid. The mating helical rotors create a progressive cavity which opens to admit fluid, seals itself off and then opens up to the downstream side to release the fluid.

This happens in a continuous fashion and the flowrate is calculated from the speed of rotation. Nutating disk meter[ edit ] This is the most commonly used measurement system for measuring water supply in houses. The fluid, most commonly water, enters in one side of the meter and strikes the nutating disk, which is eccentrically mounted.

The disk must then "wobble" or nutate about the vertical axis, since the bottom and the top of the disk remain in contact with the mounting chamber. A partition separates the inlet and outlet chambers. As the disk nutates, it gives direct indication of the volume of the liquid that has passed through the meter as volumetric flow is indicated by a gearing and register arrangement, which is connected to the disk.

It is reliable for flow measurements within 1 percent. The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream.

The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion.

When a steady rotation speed has been reached, the speed is proportional to fluid velocity.

Turbine flow meters are used for the measurement of natural gas and liquid flow. The flow direction is generally straight through the meter, allowing for higher flow rates and less pressure loss than displacement-type meters.View NR ATI basic concept #1 Fluids and from NURSING NR at Chamberlain College of Nursing.

With knowledge of fluid and electrolyte requirements, the conditions in which these needs are altered, and the physical signs of excesses or deficits, RDs can determine safe and reasonable adjustments to PN electrolyte content.

Abnormal electrolyte levels can occur anytime the body’s fluid levels fluctuate outside of norms such as after serious burns, vomiting, diarrhoea, and excessive sweating. Infrequently, overhydration can also result in serious repercussions.
