How is anesthesia being delivered to this group?
infusion
Identify both:
Left: Bolus
Right: Infusion
What kinds of clamps are there?
Roller (Cair)
Slide
Screw
Pinch
What IV controller uses a pressure plate and compresses the IV line?
Screw mechanism which has the greatest margin of error.
What is the best manual flow rate device?
Control-A-Flow
What vertical distance goes the container fluid need to be above the venipuncture device?
75 cm
What are the types of infusion pumps?(4)
Peristaltic–rotary, linear
Cassette
Elastomeric reservoir
Syringe
What’s this?
Rotary peristaltic
What’s this?
Linear peristaltic
What kind of pump?
Linear peristaltic
What is special about the Cardinal Alaris pump?
What is the disadvantage?
(used at Piedmont)
Pulse ox can be attached
Limited number of banks that can be attached.
What is special about the Spectrum pump?
What accuracy does this pump have?
Uses colbalt blue key
+/- 5%
What are the downsides of cassette pumps?
Cassette pump
Expensive, non interchangeable
How do syringe pumps operate?
Screw devices
The Cardinal Alaris syringe pump requires what?
Have to engage the plunger to be detected.
What kind of pump?
Where do you place the flange?
Smart plate pump
What is special to know about the general plate? (2)
mL/hr and body weight is not an available setting
At least one infusion rate must be turned off or else alarm.
What is on the back of each smart plate?
Instuctions regarding dilution.
What is the accuracy of the BARD infusion pump?
What about bolus accuracy?
+/- 3% , linear rate
+/- 3% linear displacement
What make sure you do before using the BARD pump?
Must purge to make sure all mechanisms engaged.
What must dopamine be diluted to for the BARD pump?
Dilute 200mg into 50ml → 4000 mcg/ml
What happens if you use a 20 ml syringe instead of 60 ml for a BARD pump?
Delivers 1/2 the dose on the plate
Cassette pumps start very accurate then all pumps end up being about the same in accuracy. True or false?
True
What is occuring with this syringe pump infusion?
Slack in gear train and no infusion is delivered.
