The Mayo Clinic Simulation Center conducts realistic scenarios in
which trainees learn to practice CPR and other procedures.
A simulation’s purpose is to reproduce an intense situation so
students can experience the interaction of their learned procedural
cues with autonomic and emotional responses.
The current leader in simulation technology is a mannequin that
partially simulates functions found in real situations.
A trainee is reminded that it is not a real person which makes it
difficult to willingly suspend their disbelief that they are in an
actual emergency.
Lack of realism can lessen their autonomic reaction which is an
integral part of the purpose of a simulation.
If an actor could wear a simulation suit, realism would improve.
Improved Realism for Medical Simulations
Objectives
Mechanical components are the protective shroud and compressible rib
system.
The protective shroud is a 2-piece rigid vest.
The compressible rib system is mounted on the shroud and simulates the
rib cage that is compressed during CPR.
The 16 springs supporting the eight ribs in the compressible rib system are
designed to withstand a 120lb load with a 2” deflection.
The shroud is designed to withstand a 240lb load with less than 0.07”
deflection and has a 2.8 safety factor before plastic deflection.
Design
Protective Shroud:
A plaster cast of a representative human form was made.
Fiberglass was used to give the plaster cast more strength.
Steel bars were rolled to fit around the cast.
The rolled bars were welded together to the desired geometry.
Compressible Rib Systems:
The ribs were steel bars shaped with a round-over bit on the mill and
cut by a band saw to create the shape of an actual rib.
Holes were drilled into the ends of the ribs to insert the spring legs.
Manufacturing
Graphical User Interface (GUI)
The administrator of the simulation controls the SimSuit EKG
output. A graphical user interface (GUI) was created using
MatLabTM. The GUI will allow the administrator to select different
heartbeat waveforms for the SimSuit to output to an EKG monitor.
Generating a Digital Cardiac Event
Why?
• Doctors need to provide specific
cardiac events for training
• Events need to accurately
reflect real world cardiac
signals
• Events need to be able to
change quickly to reflect the
training scenario

Safely perform basic procedures associated with CPR training on a
live medical simulation actor wearing the SimSuit.
The SimSuit incorporates choice functionalities into a prototype
proof-of-concept medium to foster future development.

Current Simulation Technology
How?
• Events are generated
using MATLAB software
• Wirelessly transmitted to
suit and converted to
analog signals
• Signals are then pushed
to and displayed on EKG
machine.
Constraints
• Chest compressions:
2” compression at 100-125lbs
• Electric Pulse Output:
EKG voltage is less than 25mV
• Realistic:
Looks like the actor’s chest (albeit large)
Allow actor to walk, talk and lay down
• Actor ingress and egress from the suit
Pinned hinges were created to
facilitate taking the suit on and off
Brackets were welded on the shroud
to mount the torsion springs and ribs
Foam lining was added to
provide comfort for the actor
