European Journal of Nuclear Medicine and Molecular Imaging. (39)S528-S529. Tip: If you hear someone say give “10 cc” of this medication, cc is the same as mL. Therefore, 10 mL equals 10 cc. Reading a 10 mL Syringe This is a 10 mL syringe. Each line measures in 0.5 increments until it reaches a total capacity of 10 mL. Barrel with a readable scale: this is where you will match up the top of the plunger seal (see image at the side) and the line on the scale with the amount of medication you need to administer. Most scales on the barrel are in mL (milliliters) or cc (cubic centimeters). If you are administering insulin you will use a syringe that measures in units. NOTE: always determine the capacity of your syringe because each syringe has different measurements on its scale..hence each line represents a different increment of measurement (more information on this below).

If we apply gravimetrics to the preparation process, and those gravimetrics correct the concentration computed for the vial based on detecting the addition of 9.4 mL rather than 9.6 mL, it is still only an approximation since we cannot know what was really in the vial in the first place, by a surprisingly wide margin. The range that was 830 mg to 1245 mg is reduced to 870 mg to 1200 mg. Since many gravimetric systems have an acceptable error in the ±5% range, there’s not much of this process they can ameliorate. What they can do is present evidence that suitable mass of something was transferred from one container to another. And that’s valuable. Given all the inherent error in the systems we operate, the best we can do is to operate those systems as best we can. This means: The most accurate syringe in common use has an accuracy of ±4% when its nominal volume is 5 mL or greater when delivering at 50% or more of its nominal volume. Syringes below 5 mL are accurate if they can deliver within ±5% when measuring 50% or more of their nominal volume. For a 1 mL syringe, this means that we know, at best that measuring a 1 mL volume in that syringe will deliver somewhere between 0.95 and 1.05 mL.Syringe, 1M silicone feed tube, sinker, PVC protection sleeve, aspiration, vent and dosing cannulas, set of spares for valve, operating instructions.

However, there are problems associated with the dead space in syringes: medication waste, [4] disease transmission, [2] and inaccurate dosing. [5] Specifically, there is some data to suggest that disease transmission for people who inject drugs and carry Hepatitis C virus can be reduced with the use of low dead space syringes. [6] Low dead space syringes reduce this risk by minimizing the amount of space within the syringe for blood to enter. [7] History of needle and syringe designs [ edit ] Those of us who remember our basic high school chemistry may recall that we were introduced to the concept of something called ‘ significant figures’. There were two fundamental lessons from that concept: If 50% of people who inject drugs switch to low dead space syringes an estimated reduction of 33% of new HIV, and Hepatitis B and C infections will occur.
