inside this video right here i'm going to walk you through the three main emt lessons to help you get prepared for emt school and for emt national registry these three lessons trip up students watch till the end of this video they will not trip you up anymore here we go [Music] hey everyone it's the paramedic coach here if you're watching right now hit the like button down below smash that like button hit subscribe down below as well tap that notification bell and very important here make sure to watch this entire video hit like and subscribe but make sure you watch the entire video now today we're talking about the three things that trip up emt students that are in school and studying and preparing for your national registry now number one i'm gonna go over today full lesson heart blood flow the four types of shock and finally sympathetic and parasympathetic if you watch this entire video right here you will never ever get tripped up with these topics ever again and you will get so confident by watching this video over and over again that you'll be able to teach other people what i'm about to show you here once you have it down cold now here we go all right everybody we're starting off with heart blood flow now there's a few things here i want to show you it's so important for you to understand this heart blood flow now here it is now first i want to start with what is the svc and the ivc what does that mean so first we have the svc stands for superior vena cava and then we have the inferior vena cava now superior means i should put it above i should put it up here it's so great i should put it up superior means up above okay now inferior means i don't want that i'm gonna put it down i'm gonna put in the garbage inferior is down okay superior inferior okay now vena that sounds like venus that sounds like veins that sounds like the venous system right okay now why is that important i'm going to tell you right now look here when we're talking about heart blood flow artery think away from the heart vein or venous system towards the heart where's this going blood flow towards the heart and that blood flow is deoxygenated blood it's blood that's already been passed off what do you mean evan let me explain a little bit more for you hang on hang in there the heart is the pump of the body okay the job of the heart is to pump blood around our body we have cells all over our body so we use the blood vessels as the pathways the highways the body to get the blood and the oxygen to our cells okay now the lungs we think lungs think of oxygen we breathe an oxygen right that's how we get oxygen to our body so the heart has to link up has to partner up the heart and the lungs have to be together and become partners does that make sense okay now how how do we get the heart to partner up with the lungs that is hard blood flow that makes sense okay now let's dive in a little deeper so right over here when blood returns to the svc in the ivc that is blood that does not carry oxygen anymore because it already gave it oxygen and veins go towards the heart so the whole pattern's restarting again and here we are now you're learning the blood enters the right atrium now let me give you a pearl about the atria and the ventricles the what the atria right atria left atria ventricles right ventricle left ventricle atria think they're smaller they're weaker they're not as strong as the ventricles so the atria is going to pass the blood down to the ventricles and then we're going to give the ventricles each one a very important job to do they'll each have a separate job okay now we're gonna go from the right atria gonna pass that blood off to its stronger ventricle okay through the valve to the tricuspid valve try goes through here now i'm gonna give the right ventricle a job to do its job is to find the oxygen it needs to get oxygen for the heart that's going to be the job of the right ventricle we need to get oxygen so now okay how do i get oxygen in this blood flow well it's not here i gotta go to my from the lungs right but how are we gonna do that well i told you arteries are away pulmonary artery okay so we take the blood flow we go like this here we are and there's your pulmonary artery because arteries go away from the heart in heart blood flow so now where the lungs have the oxygen at the right ventricle needs to actually complete the job you're with me okay so let's go evan that's great the right ventricle completed its job and got it got the oxygen great well now we use the pulmonary artery to go the ones what do we do now how do we get that blood flow back to the heart so we can so we can what pump blood to the rest of the body how do we do that veins go towards the heart we create the pulmonary vein that goes right here back towards the heart you're with me so now with left atria and what did i tell you about atria they pass down to their ventricle because a ventricle has a job to do and it's stronger right we go through our mitral valve here i'm going to put mit now we're here left ventricle i'm going to give it a job to pump blood to the rest of the body and it's going to partner up with the aorta to do just that my friends that is heart blood flow we're now going to dive in we have two more lessons if you enjoyed that remember you want to watch the entire video we're moving on to the four types of shocks now here we go let's get into the four types of shock you gotta understand and know you're gonna get this right now so hang with me so remember shock is hypo perfusion if i'm perfused in my body what that means is there's blood and oxygen going all the cells in my body right okay hypo is not enough hyper is too much so if i'm hypoperfused or i'm in hypoperfusion i'm not getting enough blood and oxygen to my body which means i'm in shock we're going to find out right now which one of these shocks that we may be in that makes sense okay great now here we go so first we have cardiogenic shock cardiogenic shock what that means is it's the heart's fault the heart itself has caused that type of shock it could be an mi a heart attack right so a coronary artery that supplies blood flow to the heart is blocked it's there's too much plaque in there that's an mi okay chf active chf that's congestive heart failure right so that patient they're in cardiogenic shock because the heart either had a heart attack or an mi it's the heart's fault that the patient is in shock right now and not perfusing their body does that make sense okay great next thing we're going to talk about here is obstructive shock so with obstructive shock that means there's a stopping of blood flow in a body now let me explain if i am here and i get shot in my right chest my lung is going to collapse and why is it collapsed because the air pressure there's air from the outside world entering here going in here pushing on the lung pushing the pressure over what's over here my heart well if the pressure pushes on my heart my heart's going to fail as a pump which is going to stop blood flow that's obstructive shock did the heart do anything wrong heart did nothing wrong but blood flow was stopped that happens in tension pneumothorax that happens in pulmonary embolism if i block the pulmonary artery blood flow stops did the heart do anything wrong nope it's a stopping of blood flow cardiac tamponade well around the heart there's a problem a trauma a pressure heart's fall no it's around but it stops blood flow you follow me that's obstructive shock now the next two we're going to talk about i have distributive shock and hypovolemic so here's distributive and i'm going to put in the screen here the three types okay we have sepsis anaphylaxis and neurogenic so these three types are the subtypes under distributive shock so there's four major types of shock but distributive has three subtypes okay i just talked about those now i want to go through each one individually then i'm going to give you the big pearl that you gotta know about distributive shock so sepsis means you have bacteria in your blood if i have pneumonia if i have uti and then that bacteria says you know what i'm gonna enter the bloodstream i have now bacteria in my blood i'm septic that gets worse and worse and worse you enter septic shock it's a systemic infection in the body okay now the next piece anaphylaxis if i just have hives on my arm i'm having a simple allergic reaction take some benadryl and watch out okay now if i have hives and nausea and vomiting hives and wheezing hives and strider if i have hives and all that stuff two or more body systems means i'm in anaphylaxis when that gets really bad which it will these things continue if you don't treat the patient you enter anaphylactic shock right it could be insect could be a medication it could be a food right so that's anaphylaxis okay now the final piece is gonna be neurogenic that simply has to do with the brain and the spinal cord okay now the final piece here we're going to talk about is hypovolemic but before i do that you're going to want to stay and listen to me here this is the big pearl with distributive shock with distributive shock they are not able to compensate like the other types of shocks the epi the norepi that gets released in your body when you're bleeding out to try to keep you alive that doesn't happen in distributive shock so what happens is instead of your blood pressure being let's say 80 over 60 it's 80 over 30 80 over 40. so what happens is you have that abnormal vasodilating of your blood vessels you get sick very very fast with distributive shock so when you hear distributive thinking abnormal blood pressure and abnormal vasodilating they cannot compensate like the other people can okay now finally is hypovolemic hyperbolemic has to do with blood loss fluid loss okay so i can be severely dehydrated hypovolemic i can bleed out hypovolemic okay it's gotta do it blood or fluid loss it's the classic shock i get shot i'm bleeding now i have limit make sense this right here is your four types of shock keep watching over and over again so you have it down cold and let's move on now to the next piece which is sympathetic versus parasympathetic with our nervous system here we go everybody you've made to this part of the video we're talking about sympathetic first parasympathetic now let's start off with this the sympathetic nervous system i want you to think of as fight or flight like you're running for your life the parasympathetic i want you to think about laying on the couch and you're resting and digesting two different things two polar opposites okay that's why i want you to get your brain thinking about these two nervous systems in our body okay now here's a second thing i want to tell you about okay you might not know this the sympathetic nervous system inside our body we actually have epinephrine and norepinephrine that gets secreted in our bodies when we go into this fight-or-flight mode that's what causes a lot of this stuff does that make sense okay remember that when i go through this and it's all going to click so what's here's a whiteboard okay so we have sympathetic on over here parasympathetic over here now let's start with the eyes another way of looking at this is sympathetic and parasympathetic man so we have sympathetic man over here think about a man on cocaine parasympathetic man thing about a man on heroin two different people look at the reactions they're very similar to somebody who may be on drugs if you think about it like that you'll always remember in your brain so a sympathetic response but the eyes would be right here which is a dilation a dilated pupil with parasympathetic it would be constricted think about it if i'm running for my life would i want pinpoint pupils no i don't want that i want my eyes open right now we move on from there we have the heart so with the heart and the lungs here's what i want you to think about if i'm running for my life well what did my heart rate go up right it would correct if i secrete epinephrine norepinephrine my heart rate goes up that makes sense right so my lungs relax wait a second is that why we give epinephrine to peel with asthma anaphylaxis yes it is yes it is for effects is it clicking now are you connecting dots i hope so now if i'm running for my life do i really need to worry about my stomach and my liver and my intestines moving things along no i don't so those processes in the body are inhibited so i call that off that makes sense okay great now with parasympathetic with the heart and the lungs the lungs constrict a little bit not like you're having bronchoconstriction but just don't relax there has to be an opposite to relax so we call that medicine constrict okay now with the heart what's to happen is we're going to lower our heart rate because we're resting and digesting right well digesting that sounds like right here stomach liver intestines are now on and we're moving forward with that gi process does that make sense i hope i clear this up for you hey if i did put a comment down below and say evan paramedic coach you've cleared it up i got one more message for you everyone i'm so proud of you for taking action on this video we went through three major lessons to help get you through emt school and help you pass those national registry boards everyone proud of you now if you enjoy these lectures and you want more i've actually put together an entire video vault over 180 plus videos and growing there's a lot more than just three topics in emt school in national wrestling a lot more to go over so i've created a video library you can see the link down below i actually give you a lifetime access to the course one payment you get a lifetime access you can click the link down below it's prepare for ems.com it's my life's work and you also get access to our private community group where we have in the thousands of students taking action on the course materials and getting this stuff down for school and for national mastery and for somebody out there right now who's getting ready for school get access to that because you'll be more than prepared my friends hope you enjoyed this video hope i cleared up these three topics so now you can pass it on to your fellow classmates and they can understand this which is going to decrease failure rates and ems and that's my job here as the paramedic coach i'm always here for you get access down below to the video course and i will see you next time gotta go take care don't waste any time don't don't be hesitant and just do it because i know this program works and i know it's it got me to where i was where it's been a year without school from emt to hey i passed my test and 70 questions like go for it you could do it like do not hesitate and don't waste any time i went through it i i spent the time and money in other areas and i'm just gonna let you guys know that uh this was everything i was searching for the whole time the first couple videos i watched um what i noticed it just i i just immediately started connecting dots um on some of these things i didn't have graphs if you're looking for a different way to to learn and absorb the content um in a non-threatening way um in a caring way then i would absolutely recommend the program you
