These are the smallest-sized measurements you can make accurately with this particular syringe. The arrow is pointing to the 0. Typically, the point where the plunger tip makes contact with the barrel is the spot to line up with the amount of liquid being measured. But plunger types can vary across brands and thus may need to be read slightly differently. Some plunger tips are plastic while others are rubber.
Some are the same shape as the slip tip opening of the syringe, while others are flat, and still others domed. Below are some general tips from the layperson withdrawal community for how to read several different types of plunger tips. The image above shows a 1mL syringe with a plastic plunger tip in the shape of the slip tip opening. As you can see, the dose is measured from the widest portion of the plunger tip—not from the end of the plunger tip.
The image shows a reading of 0. The image above shows a 3mL syringe containing liquid with a flat rubber plunger tip. For this particular syringe, the dose is measured by lining up the top ring of the rubber plunger with the desired calibration marking on the barrel. The liquid amount in this syringe is seven tenths of an mL Translating this into a decimal gives you 0. The image above shows a syringe with a domed plunger tip.
The dose is measured by lining up the top ring of the plunger tip with the 5mL calibration marking where the arrow points. This means there is 5mL of liquid in this syringe. Do not use the tip of the dome or the lower ring of the plunger tip when reading the amount of liquid in the syringe.
Using Syringes. Parts of a syringe A syringe is made up of three parts: the tip , the barrel , and the plunger. Operating a syringe To operate a syringe, first make sure the plunger is pressed down to the bottom of the barrel.
Understanding the units of measurement on a syringe Depending on the capacity of a syringe, its primary measurement-line markings may be in milliliters e. In other words, 0. Reading the calibration markings Here's how to read calibration markings on a syringe: Determine the increment between the visible numbers.
Determine the increments of the smaller markings. See the figures below for other examples. Accurately measuring the amount of liquid in a syringe Typically, the point where the plunger tip makes contact with the barrel is the spot to line up with the amount of liquid being measured.
Plastic plunger tip in the shape of the slip tip opening The image above shows a 1mL syringe with a plastic plunger tip in the shape of the slip tip opening. Flat rubber plunger tip The image above shows a 3mL syringe containing liquid with a flat rubber plunger tip. Domed plunger tip The image above shows a syringe with a domed plunger tip. An oral liquid medication must be given by mouth to be effective.
An injectable liquid medication must be given by injection beneath the skin to be useful. Some injectable medications require that the medication is inserted into the muscle to be most effective. It is important that you understand how to read the syringes that are sent home so your pet gets the proper amount of medication at each dose. There is some confusion about metric words like milliliter ml and cubic centimeter cc. These are just different names for the same amount of volume.
In other words, one milliliter 1 ml is equal to one cubic centimeter 1 cc. There are different kinds of syringes that may be used. If your pet needs only a small amount of an oral medication, you may receive a syringe that looks like this:. This is a three-tenths milliliter syringe.
Calculate the amount of liquid by counting 0. Make sure you continue to hold the syringe with the needle end facing upward. Use the following examples: If the top plunger ring rests one large line and two small lines from the top of the syringe body, then there are 0.
Remember that the line closest to the needle is zero, so that if the top ring of the plunger rests two small lines below this line there are 0. If the top ring of the plunger rests three large lines and four small lines from the top line of the syringe body, then there are 0.
Draw liquid into the syringe by inserting either the tip or the needle into the liquid and pulling the plunger upward. Turn the syringe so that the tip or needle points upward and you see the numbers at the side of the syringe in proper position. Note the position of the plunger ring closest to the needle or tip and the number to which it is the closest. Remember that the line closest to the tip itself is the zero line.
Three lines below the "3" mark equal 3. Four lines below the top mark equal 0. Draw liquid into the syringe by inserting either the tip or the needle into the liquid and pulling the handle upward. Note the numbered line closest to which the plunger ring nearest to the tip of the syringe rests. Add 1 mL for each line below it and above the next numbered line. If the top of the plunger rests three lines down from the line marked "5," then there are 8 mL of liquid in the syringe.
If it rests two lines down from the line marked "15," then there are 17 mL of liquid in the syringe. Do not attempt to read insulin syringes using this information.
