3. When utilizing ultrasound guidance, place ultrasound gel on the model or on the
ultrasound transducer in adequate quantities so that the probe slides effortlessly across
the surface of the model. Add more gel as necessary.
4. Adjust the ultrasound system controls per the manufacturer’s instructions, increasing and
decreasing the depth and gain controls until the desired image is obtained.
If you intend on guiding sharp objects into the phantom, never place the model in a
location where you might accidentally puncture yourself.
Using Needles and Catheters
1. For best performance, we recommend that you utilize new, sharp, unbent 18-21
gauge needles and associated catheter kits when accessing the structures in the
model; you may use up to 7-French Triple-Lumen catheters.
2. Do not use any needle larger than 18 gauges or permanent damage to your
model may occur.
3. Smaller bore needles (>21 gauge) can bend during use and damage your model’s
simulated tissue.
4. Aggressive repositioning of needles rather than removing and repositioning can
cause stubborn or permanent needle tracks due to the needle tip dragging through
the simulated tissue.
5. Dull needles may also cause permanent damage to the tissue. It is important to
replace needles approximately every ten cannulations.
Accessing Simulated Blood Vessels
1. Users can create a pulse in the ulnar and radial arteries in the wrist only by lightly pressing
the hand bulb to differentiate vessels from artery. Veins are collapsible with light pressure from
transducer.
2. Users can remove fluid after the vessels have been properly cannulated to confirm needle
placement. Please note that any fluid withdrawn from the vessel will require refilling.
Lack of fluid will result in diminished ultrasound image.
For instructions on refilling
your model, please refer to Chapter
