Drip chamber

Administration set
The tubing and drip chamber used to administer an IV drip
Drip rate
The number of drops per minute needed to make an IV solution infuse in the prescribed amount of time
Drop factor
The number of drops (gtts) needed to make 1 mL of IV fluid. The larger the drop, the fewer drops needed to make 1 mL.
Duration
How long in minutes or hours and IV infusion is ordered to run
Extravasation
Condition in which an IV needle or catheter calls from the vein and causes tissue damage by leaking irritating IV fluids into the surrounding tissue
Flow Rate
How fast an IV infusion is prescribed to run- the number of mL delivered in one hour.
Fluid overload
An accidental infusion of IV fluids and a much faster rate than was ordered, causing harm to the patient. Sometimes called a runaway IV.
Infusion
To run IV fluids into the body
Infiltration
