Triaging an Earthquake: Michelle Khare's Simulated Mass Casualty Shift

Open on YouTube ↗
Overview

In this episode of Challenge Accepted, Michelle Khare tries to act as triage officer in an emergency department during a mass casualty incident (MCI). She is not a doctor, and the hospital is not real. The production built what the team calls a "live-action hospital video game": a one-hour simulated MCI with more than 30 actors playing patients and real doctors and nurses as staff. Michelle has to make split-second decisions with only one day of training. The episode asks how close the TV version of emergency medicine is to the real thing, and what it feels like to decide who gets care when there isn't enough to go around.

The Setup: An Earthquake and an Unknown Number of Patients

The scenario opens with simulated news reports: the largest earthquake to hit Southern California in two decades, more than 160 aftershocks, and about 500 people hurt. Patients will arrive by ambulance, on foot, crawling, and in private cars, and nobody knows how many are coming. The trainers say that uncertainty is why triage matters. Michelle has to sort everyone who arrives.

Her job as triage officer is to quickly assess each arriving patient and assign a color based on injury severity, with the goal of saving as many lives as possible. One of the organizers compares the experience to the TV show The Pit, with one big difference. On TV the actors have scripts. Michelle does not know what is coming and has only a one-day crash course to rely on.

The training team includes Dr. Mike Varshavski, a board-certified family medicine physician and online medical educator, along with Ryan and Brett. The production says Dr. Mike was brought in to make the simulation as realistic as possible because he still sees patients every week. Dr. Mike says family medicine training does not fully prepare him for an MCI either. He calls Ryan and Brett the experts who both handle these situations in real life and teach them to doctors, and says he expects to learn a lot himself. One trainer says what Michelle will go through is very similar to the training they give all their emergency department staff.

The START Triage Algorithm

The core tool is START triage, a flowchart that gives medical professionals a starting guideline for assessing patients quickly as they arrive. The stated aim is to do the most good for the greatest number of patients. It uses four categories.

Green is for the most minimally injured. The first question is whether the patient can walk. If they can, they are green right away. The trainers demonstrate by asking a simulated patient to walk toward them.

Yellow, or "delayed," is for patients who definitely need care but not immediately. They cannot walk but still have stable vital signs and mental status. Michelle learns the checks in order:

  • Is the patient breathing, and is the respiratory rate under 30?
  • Perfusion: press on a fingernail, and if the color returns from white to normal in under two seconds, move on.
  • Mental status: can the patient follow a simple command, such as waving a hand?

Red is for the most critical patients who need immediate care. Something is abnormal in their breathing rate, their perfusion, or their ability to respond to and follow commands. In the demonstration, a patient who cannot walk and is breathing at 40 breaths per minute is tagged red.

Black is for patients who have died or for whom little can be done. The trainers stress that this does not mean ignoring them. These patients still receive palliative care, but the resources available on a normal day are not there. In the practice run, a patient is not walking and not breathing. Michelle is taught to reposition the airway with a head tilt–chin lift. When she asks about CPR, the trainers say it is not part of the algorithm: with about a minute per patient, they cannot commit that many staff and resources to one person. They tell her they like that she thought of it, but the patient gets a black tag.

Michelle says she hesitates to put the black wristband on anyone. A trainer replies that the algorithm exists for this reason. It lets you do a calculated evaluation that "takes the emotion out of it." They also warn her that after real incidents, staff often break down because they have been suppressing their emotions for so long, and that she should expect to feel very stressed after the simulation.

The First Wave: Easy Greens, Then Ambiguity

The first challenge is a wave of patients from a collapsed apartment building. The first few are simple. They are walking, talking, and responding, so they get green tags and are sent inside. One man with cut-up knees tells her to help someone else first.

Things get harder quickly. One woman can walk but is confused and doesn't seem to understand that she has cuts on her forehead. Michelle tags her yellow. She describes triaging this kind of patient as trying to hold a conversation while doing a math problem in your head: calming the patient while trying to picture the flowchart. A trainer points out that patients are human and give imperfect answers. If you ask for a thumbs-up and don't get one, you can easily put someone in the wrong category. Meanwhile staff keep reminding her that more patients are waiting and that one of hers is wandering off.

Then a man arrives with his intestines exposed. A trainer tells her the visible injury is not the important part and asks what she is basing her decision on. She tags him red because he can't walk and is short of breath. On closer look, he is actually breathing very slowly, but he stays red.

8:40

Treating the Red Patients: An Evisceration

Triage is only part of Michelle's job. She also has to perform procedures on the red patients. The trainers put it this way: in front of the hospital you triage, inside the hospital you treat. All the medical professionals in the simulation are real doctors and nurses, and they have been told to carry out her orders even when she is wrong.

The first treatment case is the man with the evisceration, meaning bowel protruding through a cut in the abdominal wall. He is tachycardic and on oxygen. Michelle correctly says the wound needs to be covered and dressed and a surgeon called right away. The trainers explain that you should never push the abdominal contents back in. The patient needs surgery, and the immediate goal is to protect the bowel. They walk her through it: a large trauma dressing soaked in sterile saline over the exposed bowel, then an occlusive dressing to hold in moisture, then tape. The operating room is called and she moves on.

In an aside, Michelle explains that the real "Dr. Khare" is her father. She was once on track to become a physician like him before becoming a YouTuber, and she calls this episode her chance to make him proud.

10:54

Mistakes and the Domino Effect

The trainers soon see a serious problem. Michelle is miscategorizing patients, panic is setting in, and she is freezing. One man with a chest injury can walk, but only with help. She first says green, then switches to red. A man who says his wife cannot walk gets both of them tagged green. A bystander yells "Green, red, green, red. You're an idiot."

The trainers explain why this matters. Each color sends a patient to a room with a limited number of beds, staff, and supplies. An over-categorized patient takes resources from someone who needs them more. An under-categorized patient may not get the care they need and could die. They call this a domino effect: an early mistake can cause a lot of harm later. Michelle sums it up as a resource allocation problem, and the trainers agree.

After the first round, Michelle says she felt completely overwhelmed. The trainers remind her that secondary triage always follows. Patients' conditions change, usually for the worse, so there is a built-in reassessment step to catch mistakes early. She says she will try to be more confident.

13:05

Secondary Triage and the Primary Assessment

Inside, the trainers teach her the primary assessment, a basic trauma check in a fixed order. A is airway: is it clear? B is breathing: is it affected, and are breath sounds good on both sides? C is circulation: is there a pulse, and is there major bleeding? The trainers say most life-threatening problems show up in these three areas. They also add a practical warning not to run inside, because it is easy to get hurt around sharps.

Using this check, a red patient turns out to be more stable than her tag suggested. A trainer asks why she was classified red and suggests moving her down to yellow. Michelle realizes she has wasted two gurneys. The trainers note that fixing this is not free either. Moving patients between zones takes staff time, and in an MCI that can cost lives.

14:21

Patients in Pain and Being Honest

Michelle treats a woman who has glass in one eye, blindness on her left side, and an ankle injury that keeps her from walking. The woman is frightened and asks whether she will ever see out of that eye again. Michelle has an IV placed and orders morphine. A trainer says they try not to lie to patients, and that they don't tell people "you're going to be okay," but that reassurance matters a lot in these moments. Michelle tells her they are doing the best they can.

Next is a construction site lead with a crush injury to his abdomen who keeps asking about his crew. Michelle agrees he needs pain medication and a CT scan, and 4 milligrams of morphine is ordered. In the chaos there is confusion about whether the order was for anxiety or for pain, and a trainer urges her to ask questions rather than guess.

15:38

Intubation

A patient on an EMS gurney becomes unresponsive with very low oxygen saturation. A trainer comments that disruptions you can't plan for keep coming, and being pulled in different directions is one of the hardest parts. The team bags the patient, with one breath about every six seconds, while an IV is started so medications can be given for intubation. The trainers explain that intubation secures the airway with a tube down the throat and also lets staff breathe for a patient who isn't breathing.

Michelle holds the laryngoscope in her non-dominant hand so she can control the tube with her dominant hand. She looks for the epiglottis and chips a tooth along the way, then jokes "Malpractice." With step-by-step coaching she places the tube, removes the stylet, and attaches the bag. She checks the stomach first to confirm the tube is not in the esophagus, then hears breath sounds on the right. Oxygen saturation rises to 94. She has the tube secured and orders 50 micrograms of fentanyl, 2 milligrams of Versed, and a propofol drip. Following protocol, she asks someone to repeat the order back.

17:55

A Child, a Language Barrier, and a Woman in Labor

The trainers say an earthquake produces many scenarios at once, plus surprises. A young girl arrives who can move but cannot walk. Her caregiver speaks Spanish, and Michelle tries to communicate in limited Spanish. The girl seems disoriented and appears to have a fracture, but she is breathing and has a pulse. Michelle tags her yellow and is told to inform her staff.

Then a woman says her water broke 20 minutes ago and her contractions are two minutes apart. The trainers point out that people with problems unrelated to the disaster still come to the hospital, and during an MCI they also go through triage because everyone is drawing on the same limited resources. Michelle first tags her green, then changes her to red because she is about to give birth. She says plainly that this is "not on the algorithm" and she doesn't know what to do.

This is where her earlier mistakes catch up with her. Because she over-categorized so many patients, every operating room is full. To make room, she has to finish a procedure on one of her red patients.

20:24

The Cricothyrotomy

That patient's airway is swelling shut. Rapid intubation is considered, but the swelling is severe, so Michelle decides on a cric (cricothyrotomy). She finds the thyroid cartilage and makes a vertical incision between it and the cricoid ring, cutting through the skin. When asked how far to insert the tube, she says only a few inches so it doesn't go down into the lungs, and the trainer confirms. The cuff is inflated, the CO2 detector attached, and she listens to confirm air is reaching both lungs, not just one.

All of this happens while other patients interrupt constantly. Patients argue about who arrived first, one asks why a coworker's condition still hasn't been explained, a relative is angry that a promised phone call never happened, and staff try to keep the woman in labor in bed.

22:43

Deciding Where the Baby Is Delivered

The woman in labor is close to delivering. Michelle mentions she made a video on delivering a baby two years earlier but says she doesn't remember any of it. Staff tell her to do her best and open the delivery kit, and they prepare to cut off the patient's jeans. Then OB calls: they are upstairs, and the obstetrician would much rather deliver the baby there. Michelle agrees, decides the patient should go to the operating room, and tells the patient. The OB team says they'll be ready in five minutes.

23:44

Critical Mass and Patients Who Wait

Meanwhile her staff have kept triaging new arrivals, and every room is full. A man whose wife has the eye injury becomes increasingly angry. He says they have waited four times longer than anyone else, that newer patients keep getting ahead of them, and that his wife is going to go blind. He asks whether checking vitals is the best they can do. He is told yes, because there are so many patients.

Michelle reflects that on a normal day many of these debilitating injuries could be treated. In an MCI, you have to pick and choose to save the most lives, which can mean allowing a patient to lose her sight so resources go to saving someone else's life. She points out that this was a patient she had miscategorized, and wonders whether the woman might have been treated sooner if she hadn't made that mistake.

The trainers say the biggest risk at this stage is freezing under the noise of screaming patients and angry family members. A trainer says you need to be able to snap out of it quickly in order to respond to your patients.

26:09

A Black Tag

A man Michelle had tagged red has been unresponsive since she first saw him and is now breathing agonally. A trainer tells her he needs to be moved to black and urges her to make a decision. Michelle says that because of her mistakes every red room is full. If she had allocated resources more efficiently, there might have been space, and the patient might have been saved. She gives him the black tag. She says it is horrible to be that objective, especially knowing that outside an MCI they could have done chest compressions, and that actively walking away from someone is very hard.

Afterward she describes being so overloaded with stimuli and decision fatigue that she wants to sit and stare at a wall for a few hours. She also says she has no good news for anyone, and that not being able to give people closure is hard for her.

The black-tagged man, Brunson, turns out to have been part of the same construction crew as the injured site lead. Michelle checks with Brett whether HIPAA allows her to tell him, and then does. She explains that Brunson was found and brought to the hospital, but was unresponsive when he arrived and has died. She tells him she is very sorry.

28:49

The Grades and What the Team Wants Viewers to Take Away

The trainers grade Michelle in three categories. Triage gets an F, because she panicked at times and got caught up. Treatment gets a B-minus, since she often didn't know exactly what to do, which they say was not surprising. Communication is where they say she really shone. Working with the team, moving people around, prioritizing, and continuing to check in are what they say would actually save lives in a situation like this.

One member of the medical team connects the simulation to the real healthcare system. They argue that what this MCI showed is happening at scale, with tremendous shortages and stress as workers try to care for patients with limited resources. If people don't want "MCI style" healthcare, they say, changes are needed, starting with being kind to frontline healthcare workers and remembering they are human and under enormous stress. They add a second point: life is beautiful and limited, can be taken away at any moment, and people should be grateful for it. Another team member says most people are not sick at any given moment, but everyone will be at some point and will need care. They encourage viewers to think about habits they could change to have a better quality of life for longer.

Michelle closes by saying that even this "microscopic taste" of being the person who makes these decisions gave her infinite love and admiration for anyone in the profession. She dedicates the episode to healthcare professionals.
