Editor's Note 6/4/20
In the wake of the devastating incidents of police violence, many with racially biased overtones, the kill or be killed attitude endorsed by Dr. Grossman has justifiably come under fire. A few folks have asked (some, not so nicely) that this episode be taken down. While we sharply disagree with that aspect of Dr. Grossman's work, none of those aspects are discussed in this podcast. We feel it would be a loss to the resus community to take down this episode. Instead, please separate the things discussed here from other problematic facets of his recommendations.
===
Today I am joined by the master of all things Mind of the Resuscitationist, Cliff Reid of resus.me and the Rage Podcast. In the first ever EMCrit Book Club, we discuss a book I read years ago and recently reread:
On Combat by Dave Grossman has enormous relevance to resuscitationists. I feel the entire book is worth reading, but we zoned in on the really juicy bits.
Section I – Physiology of Combat
Chapter Two – Stress Responses to Combat
We briefly discuss bowel and bladder control as they relate to stress
Chapter Three – Sympathetic & Parasympathetic Responses
Parasympathetic backlash-a time of cognitive danger
“The moment of greatest vulnerability is the instant immediately after victory” –Napoleon
Adapt a 360 degree visual sweep for threats (keep looking at all of your patients vitals and remember to bag)
SWAT Team Acronym-L.A.C.E. liquids, ammunition, casualties, equipment; For us–check your team, immediate reset of resus bay, drink something, debrief
Burn off the adrenaline dump
Conflict with colleagues. Exercise, Punching Bags? If a horrible call is reported on the EMS phone, but never shows–run a sim to burn the epi.
Sleep Deprivation-Caffeine can be our friend, nicotine not so much. If you are too exhausted to perform, tell a colleague and take a nap.
Chapter Four – Colored Conditions
originally from Bruce Siddle, Sharpening the Warriors Edge
Heart rate and task performance: heart rates are a guide, getting there by exercise is not the same as by fear/stress, so HR is merely an associated marker
Yellow 90-120, Over 115 and fine motor skills performance degrades significantly
Red 120-150, a 145 HR seems to be the break-point for optimal performance of complex skills
Black >150 and badness ensues, (or >175 in the highly trained, they get a gray zone)
- Fine motor skills-precision tasks
- Gross Motor Skills-ape skills
- Complex-a combination of maneuvers or use of multiple body parts
SWAT team breaking down door function in condition red (or gray), but they have trained until the necessary tasks that require fine motor have been practiced till automaticity
Unified Model of Stress and Performance
We need to train how we fight
Stress Inoculation Training and (Academic Medicine 2009;84(10):S25)
We are currently wasting high fidelity simulation, it should purely be for stress training. Perhaps, we should create a hell week for our 2nd years.
Stay in yellow (alert, but with fine motor control) – yellow dot stickers to remind you
“I understand a fury in your words, but not the words” –Shakespeare from Othello
Tactical/combat breathing to stay in the color zone
Hicks' Law – procedures should only be learned one way-preflush central lines, one way to RSI.
Section 2 – Perceptual Distortions
Chapter 1 – Auditory exclusion and tunnel vision
tunnel vision – the toilet paper tube
Chapter 2 – Auto-pilot
What is drilled in during training comes out the other end in combat, no more no less
Chapter 3 – Grab Bag
Time perception is sent awry
This is why you must not squeeze a BVM when stressed.
Chapter 4 – Memory
Memories under Stress are Suspect
Self Debriefing is flawed, debrief with your team.
Section 3 – The Call to Combat
Chapter 2 – Training warriors
Need to train the puppy brain, because the doggy will be in control
Triune Model of the Brain
- Forebrain-Human
- Midbrain-Puppy
- Hindbrain-Lizard
Cleanse denial: not if, only when. Do not train to “If I get into a CICO situation,” instead, “When I get into a CICO situation.”
“In combat you do not rise to the occasion, you sink to the level of your training.” –Grossman
Principles of Training
- Never Kill a Warrior in Training-this only trains them to die. Every engagement should end in the proper behavior
- Try to never send a loser off your training site
- Never talk trash about your students-Punish in private, Praise in public
This is a great chapter for folks running courses/simulations
Section 4 – The Price of Combat
Chapter 5 – Tactical Breathing
Autogenic / Tactical / Combat Breathing
4x4x4x4x4
- Breath in through your nose filling up your belly for 4 seconds
- Hold for 4 seconds
- Exhale through your mouth for 4 seconds
- Hold for 4 seconds
- Repeat x 4
aka square breathing

Thanks for finding and sharing it. “on combat” is a very powerful book, a must read for everyone who needs to preform under stress. Really helped me understand myself and others.
thanks, Nathan
Great book and a great discussion – thanks for the recommendation Scott.

just perfect!!
Really, really great. Kudos to Weingart/Reid for sharing- tied together a lot of loose musings in my head. Gonna let it marinate a bit.
look forward to hearing my friend
David Grossman’s book was required reading for us (1 PPCLI) before my battalion deployed overseas to Afghanistan in 2006. We were lucky enough to have the Lt Col come and present the key aspects of his work to the Battalion leadership. It’s a great read, and I couldn’t agree more with the philosophy of training as we fight. I’m looking forward to listening to this podcast.
please come back and let us know how we did
The Minh Writes: Great podcast guys! I was a bit skeptical on the book and topic but you and Cliff do a good job of making some key points Certainly the martial arts training helps as you both cite. I once saw a documentary on British soldiers training on applying prehosp tourniquets and the instructor used a novel technique on making the students run a 100m sprint prior to practising the tourniquet That is good way to simulate that adrenaline surge On stress inoculation training , I agree with Cliff . You need to find a balance between making the… Read more »
Indeed my friend!
I like Mike Tysons take on fear and dealing with stress ” Everyone has a plan until the first punch to the face”
yep!
here is me and my son in our Hell week training ( photo of us going under the tyres, my son is the small boy in the foreground of shot)

how were you replying to tweets when that photo was taken?
Such a fabulous podcast chaps, on an obviously extraordinary and insightful book. I have mused over it, and the gender specificity in some of the acute stress responses described. Yes, I know, can of worms just opened. There is some discussion that women biologically feel and deal with stress differently than males (the suggested ‘tend and befriend’ vs ‘fight or flight’) This may or may not be true, but anecdotally one does see instances where males and females respond quite differently in these high stress resuscitations. I have no argument whatsoever with Dave Grossman’s excellent translation of experience into practicalities,… Read more »
And please do not misconstrue this as me saying that females are superior (I’m looking at you, Minh) as, in fact, I had the opposite in mind when penning the reply. I was simply wondering why a certain proportion of the discussion felt alien, and I pondered as to whether this was a gender proclivity, and mused on whether tuning in to the combat mentality may be beneficial to those of us of the ‘fairer sex’ (forgive me, Jane Austen).
super interesting to think about. I have not noticed in my residents a sig. difference between males and females in terms of their outward manifestations of stress, but I obviously have no insight into their inner worlds.
I wonder how much the gender specificity of Grossman’s comments would apply to a mixed gender military, like Israel.
And how much of this gender specificity is culturally based rather than gender-attached.
Loved it. Thanks.
thanks, Michael
Read his earlier work: “On Killing”. Very powerful and disturbing.
you think there is any resus applicability or just a powerful read?
No it is more on combat ptsd ect
Michelle, perhaps you should get back onto the RAGE podcast panel?
I look forward to your first book. The pen is mightier than the sword!
I came up with TEDD Team, Equipment, Drink, Debrief. I like Chris’s better though. All in all a great podcast, first read On Combat and On killing while in the army (second one not so relevant hopefully).
Great books on acute stress and the high performance mindset.
thanks again Mitchell

Another point of his is that tough decision need to be made ahead of time. Instead of deciding if you should do a cric etc. plan if I have x situation, I will cric/thoracotomy…
And I like referring to ED staff as sheepdogs 🙂
v. nice
I met Lt. Col Grossman and heard him speak at a police gathering at my church a few years back. It was eye opening and amazing to hear him speak of all his personal experiences. He spoke a lot on school terrorism etc…thanks for sharing!
great to hear that he lives up to his writing in person
Scott, Great first book club…As a military and civilian flight nurse and educator, there were great insights throughout the book and podcast. I hope to intergrate them into future training. Really enjoy your podcasts during my long drives…

As a policeman turned paramedic I am delighted to see someone in the FOAM world talking about Grossman’s work. At least from what I’ve seen in EMS, skill sets like procedural proficiency are discussed ad nauseam but mindsets are never discussed or trained. It seems like we expect people to wake up one day and spontaneously think like operators so long as we’ve shown them enough cases. Like you mentioned in the podcast, so long as you can look past the original audience I think that Grossman can teach anyone who operates in a high acuity environment quite a bit… Read more »
thanks for that site rec
I have been useing things from the book in my work and in traing of others for years. Nice to see the book one this site as well. And also nice to hear two of my “heros” finding it as usefull as i.
thanks my friend
Like Scott, I was directed to this material by the military med/special forces folks and agree it has tremendous relevance to our procedural performance. I think it is so significant that I am starting to incorporate this formally into my airway courses. Beginning this month, we have a psychologist, Dr. Michael Asken, lecturing in my Baltimore cadaver courses. Dr. Asken has co-authored a text with Grossman (Warrior Mindset) as well as a text with an ED doc (Code Calm). We hope to connect the dots between the physiology of stress, mindset training, and specific examples and techniques pertinent to airway… Read more »
This will make Rich’s amazing airway course even better!!!
Enjoyed the podcast and On Combat is one of my favorite books. The discussion on Hick’s Law reminded me of the Law of Primacy and how hard it is to break the first thing learned, if you can even do it in some instances. I do have a background in aviation and I am a firm believer in simulations and how well it improves actual performance. During sim sessions, hell is rained down on you from the time the door closes to the time it opens. Bells, lights and alarms are constantly going off in these sessions and you feel… Read more »
absolutely
We face a greater calleng on the sim side, however…in aviation you can recreate the cockpit, controls and through mechanical movements generate G force, turns/tilting/etc….only thing you “fake” is the projected visual images outside the plane. Our interface is the patient–and every one is different–and the simulators we use are hardly that–they are obviously fake, non-anatomic, not visually or tactile realistic enough to give you the “innoculation” or true stress that meaningful simulation should provide. I feel the solution is real tissue (cadavers or using fiberoptics)–to demystify the anatomy–and I am also trying to create much more realistic manikins, but… Read more »
Not to bring the comments too low, but I listened to this (great) podcast on the drive up to cover a PICU in a much smaller town and hospital than my usual shop, and 36 hours later was intubating, lining up, etc. a 3.5 kg individual with a group that doesn’t do it that often. It went great, and I credit the “battle crap” that I took before getting started. Also, spread the no-desat apneic oxygenation knowledge at least to a couple of the RTs and nurses in this neck of the woods (who raised eyebrows when I told them… Read more »
great stuff!
For most of my career I have entered into airway management with two fears (and lots of negative self-talk)…the two fears being what if I don’t get it? and “the patient is going to stop breathing and desat”….Now I go into the airway confident that epiglottoscopy will make the procedure reliable…and that NO DESAT (in all but the sickest) will prevent desaturation (or at least delay it)…its amazing how much better one performs when the pulse ox is not alarming, the nurse is not ramped up, and you have a plan of how to approach the procedure—i.e., uvula points to… Read more »
Thanks Richard,
I’m about to undertake my IC-P finals in a fortnight in Australia. You’re airway stuff has been terrifically helpful in overcoming my experience with the “two fears”. Your systemic approach has resonated with me, assisting my practice. Visualisation is such a powerful tool. I’d love to get over and do one of your courses in the future. Much appreciated!
If you need an another book, try: “Tengo Sed” – a novel about an EM resident’s experience in a surgical ICU. Cheesy, but entertaining. Scott: you should recognize a fellow trainee as the model for the evil ICU attending, “Dr. Pizza.”
I’m on it
“We are currently wasting high fidelity simulation, it should purely be for stress training. Perhaps, we should create a hell week for our 2nd years”. Dr Weingart : we have come to a stalemate with our high fidelity Sim i.e.: can’t get some folks at times to buy into the presented Sim or they just seem disinterested and only want the teaching points……….I would love to hear thoughts on how to ramp up things with “stress training”. I think my staff could utilize this and hone their Crisis Resource Management Skills. What were some of the ideas for “hell week”… Read more »
By the way………..Great book and very interesting read. Very applicable to the EMS environment.
we are actually actively plotting the 1st iteration of this concept and in the coming weeks, I’ll post some ideas and resources.
Thank-you looking forward to it.
Fantastic book club on a fantastic book! I do think the applicability is widespread. The most interesting thing is how the mind can play tricks on you. After not competing for about two years (had a little girl so not enough time to train!), I recently entered a brazilian jiu-jitsu tournament. I felt a little nervous during the day, a little more in the pre-fight warmup, and in my first round match, completely gassed out and lost, probably my saddest competitive performance. At the time it felt my opponent weighed a lot more (not really possible since we weigh in… Read more »
thank you so much for that story, my friend
Great post! As the TEMS physician for several of our local teams, i was concerned on how many of our local Law Enforcement (LE) are NOT aware of this book. I have been buying copies for a lot of our team leaders and this has been the focus of a lot of my recent education. I took a lot away from the book itself about the need for critical incident debriefing in the ED more often and tried to adjust my “care for the caretaker” discussion we have after arrests, codes, and other traumas as well. the response from staff… Read more »
absolutely!
As a senior resident/PEM fellow I totally see the value and foresight in being aware of the physiological responses to extreme stress, and already applied the tactical breathing technique! Beauty. Thank you Scott & Cliff! However, Lt Grossman seems to think that the medical community appreciates the important effects of sleep deprivation. I think we are aware of them, but more often than not we’re told to suck it up… and we use current EBM (i.e. meta-analysis of observational studies) as an excuse not to combat resident fatigue. http://www.thestar.com/news/gta/2014/03/26/shorter_shifts_dont_help_medical_residents_or_patients.htm Our pilots have been mandated to rest now for 3 decades;… Read more »
in EM, residents are never there more than 12 hours and usually only 8
Yes, since we moved to a shift-based schedule. But, in your ICU… how confident are you in a tired, sleepless resident to get a difficulty airway, or get a line without gettin multiple arterial stabs?
i think 24’s need to disappear in the ICU as well. Night float seems the way to go IMNHO
Great podcast, Scott… as always… Strangely enough I’ve worked out a few rules for myself that turned out to be in the book… one of them tricking your brain into thinking not “if” rather than “when” as a trigger point… I found it so-o helpful in numerous situations when managing a critical patient it works almost like “set-and-forget” mechanism… you “set up” a crucial point and once it comes up -you already know what to do as you have already thought it through and didn’t it becomes a breeze. I also have augmented it with “prebriefing” of the staff and… Read more »
As a grad student I sometimes have to triage my reading time, and I just now got the book. Now that I’ve read it, it’s time to make another addition to my teaching packet. Another brick in the foundation of becoming an expert/master provider. As I was reading it hit so many chords, I could have written a symphony. I was a failed special operator. When I enlisted int he Air Force I had every intention of becoming a pararescue specialist. Well i didn’t quite make it. But I did end up with what I considered the best job in… Read more »
Craig you were a total badass!!
(I apoligice for posting in such and old thread. Put perhaps someone has some tips?) On the ambulance I discovered that a good portion of stress was good for me personally. It froze the most socially dominant and belligerent senior personnel, and let some less dominant but more trained do a good job. Sometimes one even got praise later. In private life, in exercises, I have seen cognitive tunnel vision as problem: I have seen it my self, been ashamed, and learned from it. However I have also seen it in two of our slightly bellicose friends. One had after… Read more »
I started reading this book when this podcast came out and while I think there are some interesting ideas that I’ve applied in my work and in my non work life (attempting to play music) I was also really uncomfortable with the language about “warriors” and the general elevation of those in combat as being in some higher stages of heroism and morality. Precisely because that language inevitably leads to more innocent people getting killed. As with medical practitioners, I feel like a healthy amount of self doubt is something that should be cultivated, not restricted in law enforcement. If… Read more »
Paul, I agree with all of your comments on the reprehensible nature of many of these shootings. I am less clear on you placing blame on the language in Grossman’s book. I think just as valid an argument could be made that if these officers had any actual capability of controlling their stress response to perceived (and false) threats, these shootings would not happen. I have to imagine Grossman would say the same if asked.
I probably should have responded at the time. It’s not a valid argument. Grossman is encouraging police to be scared of the public. He is amping up cops fear. The whole thing is bogus. With a predictable result. Grossman tells officers that “only a killer can hurt a killer.” He asks them if “you are willing to snuff out a life to protect innocent people.” When he surveyed officers about deadly shootings, the concern he most often heard was over liability and lawsuits. He stressed to officers to “shoot first and worry about questions later.” https://www.startribune.com/fear-based-training-for-police-officers-is-challenged/487958041/ “It’s… Read more »
Scott, In the 6 years since this episode came out, my mind has been brought back to it a number of times. Namely, each time that an unarmed black man is killed by police. An exageration, of course, because clearly unarmed black people are killed somewhat routinely by police. I can’t say I’m the most informed about Grossman’s work. I started reading the book on your recommendation and remember being really put off by the sort of moral disconnect about the taking of someone’s life described in such a cool, calm way. I forged ahead a few times… Read more »
PS Scott it seems I addressed this in this thread 2 years ago. You didn’t agree then. Still don’t? At this point I can only say that my feelings have hardened on this issue.
Mel Herbert addressed this most effectively yesterday in the EMRAP video.
I personally don’t see how anyone in EM can watch the George Floyd video and ponder not just that but all the other incredibly fucked up things that law enforcement has done in the last month and not address it.
And it’s not like there’s not alternatives to military analogies for high stress fine motor control situations. Why don’t you ponder examining concert performers who have to execute fine motor control in front of 100s of people? Or jazz musicians who are doing the same in constantly changing scenarios?
I’m 100% over with military or police analogies to health care. If you have to resort to police strategies, you failed.
Here’s a noted expert on performance strategies who I find to be generally excellent.

seriously, Killology.com?
If today you’re not getting that that’s effed up, not sure what to say.
Sorry but while I’m at it…I didn’t put two and two together that both Philando Castile and Floyd were both killed in Minneapolis. Not sure if Dave Grossman taught Chauvin. But Yanez who killed Castile did attend his class. I know this is 6 years ago but I have to say it’s deeply troubling you’ve never addressed this. For someone who is an expert in science based medicine and research to have put so much stock in someone who looks like a borderline sociopath and is helping get black men murdered is more than problematic. https://www.insider.com/bulletproof-dave-grossman-police-trainer-teaching-officers-how-to-kill-2020-6 … Read more »
I was thinking of Dave Grossman today after the apparent murder of a girl in Ohio. Sounds like she was shot on sight by a cop there after she called the police herself. Hadn’t googled Grossman in a while. He’s got some super enlightened opinions about mask wearing. https://www.linkedin.com/pulse/masks-can-murder-lt-col-dave-grossman/?published=t&fbclid=IwAR2OYHtQJbgDsK_t2fcLacx9Qf9ohKl4KXsExVJHfGjfYKWUMmwbHYWLyYs I feel really sad for these cops that they’ve been hoodwinked by Grossman into committing murder. It continues to remain an absolute mystery to me how people in Emergency medicine would even begin to think that he had something of value to share. https://spectrumnews1.com/oh/dayton/news/2021/04/20/teen-dies-after-fatal-shooting-by-columbus-police- Grossman’s writing is the worst garbage I’ve… Read more »
