Environmental Control
Wireless Voice for your patient:
Vital-Sim
Both the Vital-Sim and Sim-Man level patients have
"built-in" voices that may be activated through the computer
for the Sim-Man or hand control for Vital-Sim. Both provide
limited responses, such as "No," "Doc, this really
hurts," and similar sounds. There are times though, when you may
want the patient to respond more fully and therefore, be more
interactive. Here is one method for Vital-Sim patients that works using an inexpensive
RadioShack wireless microphone. There are three parts: a
microphone, transmitter, and receiver. Laerdal also has a wireless
microphone accessory. Both the RadioShack and Laerdal units must
have the receiver plugged into a wall outlet. There are other set
ups that run on battery power and give your patient mobility for
scenarios involving transport..

1. Find your Vital-Sim control box as pictured.
2. Locate the audio input (most likely not marked so see below)
3. Locate the audio output on the back of the RadioShack Receiver box.
4. Connect an audio cable into the "High Z" jack on the
Receiver box.
5. Connect the other end of the cable into the audio input of the Vital-Sim
box.
6. Turn on the power to both Vital-Sim and Receiver boxes.
7. Connect a microphone to the RadioShack Transmitter (shown below.)
8. Turn on the power to the Transmitter (battery operated)
9. Turn OFF the "mute" button.
10. Speak into the microphone and....ta dahhhhh, the patient
speaks.
11. If not, increase the volume control on the front of the RadioShack
Receiver box.
12. If still not heard well, increase the volume control of the patient
voice through the Laerdal hand held remote control. Ramp it up to
about level 7 and try again.
Still did not work? Help!
Big hint: Cup the microphone deep in your hand.
Hold your hand against your mouth and speak softly. This will cut
down on noise from about you and also slightly alter your voice.
 The yellow
">" indicates the audio input for your
wireless microphone receiver. This is where you will
attach the cable that come FROM the receiver output. Shown
below. |

[FrontPage Image Map Component]The double
">>" is pointing to one end of the cable that
runs from the back of the RadioShack Receiver (shown) all the
way to the back of the Vital-Sim control box (shown
above.)

§-§
| [FrontPage Image Map Component]Turn on the power
to the Receiver Box. Adjus the volume control so that the
patient's voice is understood, but not so loud as to be
distorted. Bass and treble can also be adjusted to give a
more easily understood voice to the patient.
Experiment. Have fun. |
§-§
| [FrontPage Image Map Component]This particular
model of wireless microphone transmitter has an "on-off
button" and a "mute" button. The power must
be on and the "mute" button OFF to transmit. Use the
"mute" button to prevent your speaking being
transmitted. Be sure to turn off the power before walking
away. This device takes a 9 volt battery. A
microphone, perhaps from one of your older computers plugs into
the top of the transmitter. |
