• Use compatible components which have the smallest internal volume or “deadspace” to
minimize residual volumes between the syringe and the patient when administering
medications or fluids at low infusion rates (for example, < 5 mL/h, and especially flow rates
< 0.5 mL/h). This reduces the amount of time it takes for fluid to reach the patient, maintains
delivery accuracy, and reduces occlusion detection times.
• Minimize the height difference between the pump and the patient and avoid changes in the
height of the syringe module (for example, during transport of critically ill patients) to prevent
unintended fluctuations in the flow rate.
• If using multiple syringe pumps and it is not clinically feasible to have all pumps level with the
patient’s heart, place the high risk or life-sustaining medications as close to the heart level as
possible. When infusing multiple high risk or life-sustaining medications, consider placing the
ones infusing at the lowest rates as close to the level of the patient’s heart as possible.
• Avoid use of manifolds with ports containing high pressure valves. High pressure valves
require additional pressure (for example, 50 - 200 mmHg) to open and allow fluid flow. These
high pressure valves may cause a significant delay in therapy followed by a sudden bolus
once the valve is opened, particularly at low infusion rates (for example, < 5 mL/h, and
especially flow rates < 0.5 mL/h).
