2. © 2009 Delmar, Cengage Learning Syringe Volume Sizes 0.5 mL 1 mL 3 mL 5 mL 10 mL 20 mL 60 mL

3. © 2009 Delmar, Cengage Learning Syringe Calibrations Regardless of syringe’s volume, calibrated in milliliters –Except specialized insulin syringes

4. © 2009 Delmar, Cengage Learning How to Read a Syringe From top/front ring First long calibration always zero

5. © 2009 Delmar, Cengage Learning 3 mL Syringes Most common Should be calibrated using metric unit mL –Some still include calibrations in cubic centimeter (cc) Essentially identical to mL

6. © 2009 Delmar, Cengage Learning 3 mL Syringes

7. © 2009 Delmar, Cengage Learning 3 mL Syringes Shorter calibration marks indicate tenths of a mL Longer calibration marks indicate ½, 1, 1½, 2, 2½, and 3 mL Tenths of a mL written as decimal fractions –E.g., 0.1 mL, 0.6 mL, 0.9 mL

8. © 2009 Delmar, Cengage Learning 3 mL Syringes What is the volume of medication in the syringe?

9. © 2009 Delmar, Cengage Learning Safety Syringes Developed to decrease risk of accidental, contaminated needle sticks Variety currently manufactured Most health care facilities use some brand Become familiar with type used in local clinical facility

10. © 2009 Delmar, Cengage Learning Tuberculin (TB) Syringes Most common volume 1 mL Calibrated in hundredths –Noted by shorter calibration marks Each tenth calibration mark has Arabic number printed on syringe barrel –E.g.,.1,.2,.3, etc. –Noted by longer calibration marks

13. © 2009 Delmar, Cengage Learning Larger Volume Syringes Most common: –5 mL –10 mL –20 mL –60 mL

14. © 2009 Delmar, Cengage Learning Large Volume Syringes Shorter calibration marks located on 5 mL and 10 mL syringes measure 0.2 mL Longer calibration marks measure 1 mL
