Next, take the trainer to an area with a
sink and open counter space. Using the
red caps supplied, plug off the right
bronchus (the esophagus should already
be plugged). Stabilize the head on the
counter face-up (towels work well for this)
with plugged tubes hanging over the sink
(Figure 8). Carefully pour warm soapy
water (a mild dish soap works best) into
the mouth until the water level reaches
halfway up the tongue. Tilt the head back
and bring the neck up 3" off the counter-
top.
Figure 8
Continue filling until the water level covers
the tongue. At this point, take a small soft
brush and gently scrub the inside of the
mouth (a small toothbrush works well for
this). Cotton swabs can be used to scrub
inside the nostrils. When done, pull the
plug from the esophagus and drain the
water into the sink. Now pick the head up
to a vertical position and pull the plugs
from the trachea to completely empty the
system (Figure 9).
Rinsing the Airway:
To rinse the airway, follow the same pro-
cedure using clean, warm tap water.
Repeat this process until all the soap has
been flushed from the system.
Figure 9
Disinfecting the Airway:
To disinfect, repeat the standard cleaning
procedure, but this time use a bleach
solution, as specified by the Centers for
Disease Control, instead of soapy water.
Fill the system with the solution until it
reaches the corners of the mouth.
Remember to start filling with the head
flat and finish with the neck slightly ele-
vated to ensure that the solution com-
pletely fills all airway passages. Once
completely filled with the bleach solu-
tion, allow the head to sit for at least 10
minutes. Drain as described earlier and
repeat the rinsing process to flush out all
of the bleach solution. Set the head
aside and allow it to dry completely.
Using the Combitube
®
:
Thoroughly read and follow the instruc-
tions that come with the Combitube
®
. The
trainer will accept either a full-size or a
small adult tube. As with a live patient, it
may be necessary to back the tube out
slightly if ventilation cannot be established.
NOTE: Depending on tube placement, the
large cuff may not accept the recommended
amount of air. In this case, simply inflate the
cuff to its maximum volume (when the plunger
stops) and, while holding the plunger down,
detach the syringe from the blue pilot balloon,
and proceed.

Pressing the Gap key simply turns the
gap function off or on. When the key is
pressed, a message will briefly appear
that the ausculatory gap is enabled or
disabled. Also the main display will show
(at the bottom right of the display) either
AGap:Y (for on) or AGap:N (for off).
The arrow up and down keys also
control the volume of the sounds that are
present in the arm. From the main menu,
press the up arrow key to increase the
volume, press the down arrow key to
decrease the volume. The volume levels
can be adjusted from level 1 (the lowest
volume) to level 7 (the highest volume).

Blood Pressure Simulator
First, verify that the pressure line tubing
from the sphygmomanometer and the
audio line coming from the simulated arm
assembly are properly connected to the
blood pressure simulator unit, as previous-
ly described in the set up procedures.
Apply the sphygmomanometer cuff and
gauge to the simulated arm assembly in
the usual manner. Apply the stethoscope to
the simulated arm also in the usual man-
ner. Set the systolic and diastolic controls
to the desired levels. Select the auscultato-
ry gap if desired. Finally, adjust the pulse
rate control to the desired setting.

A pulseless condition can be simulated
by switching your unit to the “pulseless”
mode. Press the Menu key repeatedly
until “Set PALPATION” menu appears. By
pressing the down arrow at this point,
palpations can be disabled causing the
simulator to be pulseless. When in the
“pulseless” mode, all settings are auto-
matically reset to 0 and all blood pres-
sure sounds are disabled.
The pulseless setting will also turn off
the sounds in the arm. The pulse will
always be on unless the pulseless feature
is activated or if the systolic or heart rate
levels are set to zero. To do this, press the
Menu key four times. The down arrow
key will set the pulse to pulseless. Press
the arrow up key to turn the pulse back
on.
(See figure 10.)
Located to the
right of the Menu key is the ausculatory
Gap key.
(See figure 11.)
This key is
included to simulate the ausculatory gap
that is sometimes present between phase
1 and phase 2 sounds in which no audi-
ble sound is noted during this portion of
ausculation. This control function is includ-
ed so that the trainee can become famil-
iar with this phenomenon.
