Don’t Wait, Simulate!

manican
There’s a great opening scene in Pixar’s Monsters Inc. where a monster cracks the door of a young child’s closet, quietly approaches the bed, and then just as he’s about to scare the kid from his peaceful slumber, the child wakes up screaming. The monster is taken by surprise, screams as well, and ends up accidentally injuring himself several times. Then the alarms sound, the camera pans out, and you see that it is not in fact a real child but a robotic simulation. The monster is in training on a sound stage, being observed by both instructors and his peers, and unfortunately, he has failed to pass this part of the real life simulation.

Of course this is a computer animated movie, set in a parallel universe, but the reality of this type of simulation in our world is not far from the truth, especially in the world of healthcare.

Medical simulation is an extremely valuable tool used today to train new medical professionals, and AV technology is essential in maximizing these simulation environments. You will find simulation labs everywhere from vocational trade schools to major universities to world class hospitals. The technology is not only experienced and utilized by the student, but as in the animated example above, also by instructors and the students’ peers.

Let’s take a brief journey through the technology that makes these simulation labs so valuable from the three perspectives of the student, the instructor, and the student’s peers.

The Student

A critical component of every medical simulation is the patient. Fortunately, students don’t get to practice on actual people having major medical emergencies, so instead a technologically advanced surrogate is used. The high definition mannequins or advanced patient simulator is the first major component of a modern simulation lab. These mannequins blink, breathe, and have heart beats and blood pressure. They can exhibit symptoms of physical, neurological and psychological illness and even respond to drug administration. When coupled with an array of medical equipment like EKGs and blood oxygen meters, students can start to assess symptoms. PCs or touch screens that give the students access to the simulated patients sensitive medical history and Electronic Health Records, EHRs, can also be used in tandem. A virtualized audio system may also be integrated so the student can alert the appropriate staff of the patient’s condition through the use of the facilities code system and a public address system as well. This combination of a patient simulator, sensors, medical equipment, displays, microphones, and speakers all help to realistically recreate the environment in which the student will be working in the future.

The Instructor

If there is one thing that is certain about patients, it’s that they are all different. A simulator is only as good as it is programmed to be, and going through a few pre-canned scenarios may be helpful to some degree, but in the real world, things don’t always go as planned. It is for this reason, technology also allows the instructor to control these simulated environments. Typically there is a control area outside of the simulated patient room, where the instructor will use a control system to initiate a condition in the patient simulator. This means that a touch screen of some kind will most likely be used. A computer or processor is needed to send data to the patient simulator. The instructor can create unique combinations of symptoms and patient responses to them, keeping the student in the mode of active thinking, an important skill set to be had by any medical professional.

A camera system can also be employed to give the instructor a more detailed look at the way the student handles the initiated emergency and/or condition. There may also be a two way communication system between the control area and the simulated patient room so that the instructor can listen and even coach the student on next steps.

The Student’s Peers

Finally, technology can allow observers not directly involved in the simulation to witness it first-hand without having to be hands on.   Many simulation labs have an observation window where other students can sit and observe the simulation and the involved student’s response to the instructor triggered events. There are also displays that may show these students duplicate vital data available on the machines in the room. Those same screen may relay what type of event the instructor has triggered, so they can observe what would be the typical response of a professional given those parameters.

The cameras in the simulation room may also be leveraged with some type of codec to encode the video for live streaming over the internet or for live video teleconferencing, to make the simulation available in other rooms or other campuses live and simultaneously. These same cameras also facilitate recording for later distribution, in classroom teaching, or even a review of the active student’s role in the simulation and how they performed.

As you can see, technology has allowed simulation to reach new heights in medical schools and facilities across the US and the world. A strong working knowledge of Audio Video technology has become increasingly valuable in designing, installing, and maintaining these systems as well.

Getting Real: How Simulation Improves Medical Training

The captain peers out of the cockpit window at the runway below.  Suddenly, an emergency light blinks on the flight panel.  The controls seem stiff, unresponsive and one of the engines just conked out.  This is his first flight, and he’s not sure what to do.  Thankfully, the pilot in question was taking a training session in a flight simulator.  He’ll walk away from his mistakes and learn from hours of virtual experience.  When it comes time to fly a real plane, he’ll be prepared.

Simulation is improving how doctors, nurses and other healthcare professionals are being trained too.   In fact, the rapid advances in computer modeling and AV technology have made medical simulation one of the most effective ways to educate healthcare providers.  For example, the advantages of simulated learning systems include:

  • Simulated Instruction: According to the Society for Simulation in Healthcare, virtual learning bridges the gap between the classroom and real-life experience. Lessons delivered via streaming video, desk-top simulators and mannequins with computerized sensors are just a few of the high-tech ways medical students are getting a more hands-on approach to their studies than they’d find in the traditional classroom. Simulated instruction provides students with a very realistic experience, but without putting patients at risk.
  • Student Assessment: Conventional educational methods emphasize multiple choice tests, oral exams and written assignments. However, these methods are surrogates for competency not demonstrations of it. Simulation can replicate medical scenarios and tasks to a degree that is remarkably life-like. Therefore, medical simulators allow a more accurate assessment of student proficiency under conditions that are more realistic.
  • Simulation-Based Research: Simulation is very useful when it comes to testing healthcare devices, procedures and even evaluating the effectiveness of training regimens. For instance, novel medical techniques or new ways of administering drugs can be tried out under simulated conditions.
  • Organizational Evaluations: Simulation can help organizations and medical teams assess procedures and readiness. From disaster response to EMT training, simulated scenarios help institutions and health care professionals improve their programs.

Virtual learning offers numerous advantages over traditional methods.  Thanks to AV technology and computer modeling, virtually any clinical situation can be simulated.  As noted, medical students can make mistakes in such environment without putting patients at risk.  Furthermore, simulated sessions can be recorded so that trainees can be assessed and debriefed.

Medical simulation can take many forms from low-tech (mannequins) to high-tech (3-D virtual reality simulators).  The level of immersive experience necessary to train students will vary, but screen-based simulation offers a cost-efficient and educationally-effective way to help prepare the next generation of doctors, nurses and care providers.  For example, streaming video lessons, the capacity to record and archive simulated sessions, and the ability of students to learn at their own pace are just a few of the benefits AV technology provides.

Simulation also offers students the chance to experience a wide range of medical scenarios, procedures and equipment.  It can be used for basic education – Adobe Flash animations to teach students the fundamentals of physiology, for instance.  Or it can be used as part of complex emergency and war game scenarios.  No wonder, institutions like Johns Hopkins now see virtual training as the gold standard in medical education.
