Equipment Flashcards
Nurses role
Decision making process of equipment acquisition. Knowledge of operation of equipment to ensure safe, effective delivery of infusion therapy. Financial accountability. The public holds industry, medical institutions, and professional accountable of the safe and effective delivery of health care.
Requires air vents.
Glass system
Vented tubing is used
closed system
Air enters through a tube in the bottle that allows for air displacement
Open glass system
Made of PVC. A closed system. Does not contain a vacuum; must be flexible and collapsible. As fluid runs out, bad closes down.
The plastic system
Administration sets
Single line sets, include primary (standard) sets, secondary (piggyback) sets, and volume controlled sets
Primary Y sets
Administrations sets vary among manufacturers and drop factors, all have basic components
Basic components of administration sets
Spike/piercing pin
Flange- helps prevent contamination
Drop orifice- determines shape and size of drop
Drip chamber- pliable clear plastic tube contains the drop orifice.
Tubing- connects to the drip chamber. Average primary tubing length is 66-100 inches, secondary tubing length 32-42 inches
Clamp- flow clamp operates on the principle of compression of the tubing wall. Types: roller, screw, slide
Injection ports- serve as an access into the tubing and are located at various points
Back check valve- allows primary solution to resume after the piggyback is complete
Hub- adaptor to connect the administration set to the IV catheter or a needless system. Also called a male Luer-lock
Final filter- removes foreign particles from the infest. May be a part of the tubing (in line filter) or an add on.
Connections- they are universal. two types: slip, Luer lock
Piggy back set: Standard drop rate 10-20 drops/min. Connected to an injection port. Primary set is positioned lower than the secondary set.
Volume controlled set: metered-volume chamber set. Designed for intermittent administration of measured volumes of fluid. Standard hold 100-150 mL; neonatal hold 10-50 mL
Secondary administration sets
Needless connectors
Attached to the hub of the peripheral IV catheter and CVAD, allowing the tip of a syringe or male luer end of the IV administration set to be attached. Allow for venous access without removal of the connector, thus maintaining a closed infusion system. Appropriate flushing depends on type of connector (positive pressure, negative pressure, neutral pressure- most are this). Changed according to hospital policy, and if contamination is suspected.
Add on devices
Stop cocks. Extension sets. Catheter connection devices. Multi flow adapters and Y connectors. Blood sampling systems. Closed system drug transfer devices. Filters.
Flow control devices
Gravity dependent flow control: roller clamp. Manual flow regulators (dial-a-flow). Pressure bags or cuffs. Mechanical pumps. Elastomeric balloon pumps. Spring based pumps.
A female connection point of an IV cannula where the tubing or other equipment attaches
Hub
Area of the IV tubing usually found under the spike where the solution drips and collects
Drip chamber
Point of entry
Port
Space within an artery, vein, or catheter
