Infusion system?
An infusion system is a device. Deliver fluids or drugs in solution to the patient. Control
automatically flow rates & volume.

7. Positive Displacement Pumps
 The positive-displacement pumps use a motor to provide a positive
displacement of fluids.
 The mechanism of action for these pumps is either peristaltic or piston
based.
Peristalitic mechanism Piston mechanism

8. Volumetric pumps
 Volumetric pumps are often used for continuous drug infusion when larger
quantities need to be infused, especially when a higher infusion rate is
required.
 Volumetric pumps are powered by mains or battery. The rate is selected in
millilitres per hour (ml/h) or micrograms per kilogram per hour (µg/kg/hr).

10. Syringe pumps
 Syringe pumps are often used for low flow rate infusions, when a more controlled
flow is required. The maximum volume is limited to the size of the syringe.
 They are incorporated with a calculator mode allowing clinicians to set features
such as patient weight, infusion rate, and concentration of drug.

12. Multichannel pumps
 The multi-channel pumps are designed to allow the administration of two or three
infusions simultaneously.
 The disadvantage with these pumps is the possibility of an incompatible mixing.

13. Ambulatory pumps
 These are pocket size pumps, which use linear peristaltic mechanism and have a
fluid container in the form of a small floppy bag or cassette.
 The pumps are designed for users who need to wear them for long periods and
they have good alarm and display systems.

15. Programmable volumetric infusion pump
(contd…)
 It incorporates a peristaltic (tube squeezing) pump mechanism.
 Flow rate is a function of both pump speed, tubing inner diameter, and
tubing elasticity.
 An ultrasonic sensor is used to detect the drop which then signals to the
microprocessor that a drop has been detected by the flow sensor.
 The heart of the system is a central processing unit. It has a 2.5 MHz
external clock supplied by a crystal.

20. Policy
All regulated health care providers (RHCP) may operate infusion pumps (other than
syringe pumps) according to their scope of practice once the following competency
requirements are met:
a) Self-Directed Infusion Pump e-Learning Module on My Learning Edge (MLE)
b) Passing score of 80% on the Infusion Pump quiz
c) Submit the completed/signed Infusion Pump Competency Checklist to the Clinical
Nurse Educator and/or the charge nurse from Medical Imaging.
d) Annual recertification on Infusion Pump education on MLE
20

21. 21
An infusion pump and tubing should be used for all patients receiving IV medications, solutions and
blood/blood products. In emergency situations, IV infusions may be administered without an infusion
pump in order to prevent delay of treatments.
All RHCPs should select the appropriate CCA on an infusion pump which should correspond to the nursing
area that they are working in.
Infusion pumps MUST BE used on:
• High alert medications/infusions (Medication Administration Policy II-226).
• Medications which specifically state “infusion pumps required” in the IV manuals posted on the
Intranet.
• Paediatric/neonatal patients who require IV infusions and medications.
Exceptions: An infusion pump will not be used in Day Surgery, Operating Room, Post Anaesthesia Care Unit,
and Endoscopy. IV infusions will be administered via gravity using a buretrol in these areas.
