Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Medical Calculations

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Desired Dose Specific quantity of medication needed Most doses expressed as weight: – Grams – Milligrams – Micrograms May be standard or based on body weight

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Dosage and Volume on Hand The amount of drug available in a solution. Concentration is the weight per volume.

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Calculating Medication Doses Volume to be administered = Volume on hand (desired dose) Dosage on hand

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Calculating Infusion Rates Medicated Infusions Drops/minute = Volume on hand x drip factor x desired dose Dosage on hand

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Calculating Infusion Rates Fluid Volume Over Time Drops/minute = Volume to be administered (drip factor) Time in minutes

Bledsoe et al., Essentials of Paramedic Care: Division 1 © 2006 by Pearson Education, Inc. Upper Saddle River, NJ Exact flow rates are critical in pediatric patients since they cannot tolerate over- or under doses.
