    I am a nursing student in my final semester and your MedCram videos have been incredibly helpful. They provide that added background information that may not be available during lecture to answer the "why" questions. Thank you and keep up the great work!

    Hi Doctor, I love all your topics very much. They are all explained clearly. can I ask for your help to do on other lecture topics? If its possible, I hope you can explain also topics such as ECG, acute coronary syndrome, myocardial infarction, pneumonia, TB, hepatitis, neoplasm, gastritis and ulcer, intestinal obstruction and inflammatory bowel disease. Hope this long lists wouldn't be too demanding. its okay if you wouldnt like to cover all. but I really hope you can choose from some of it.

    @brudforce 7 ปีที่แล้ว

    Dear Dr. Seheult,
    Thank you for the wonderful video, it is very helpful and much appreciated.
    I would just like to confirm that the reason for a decrease in EF for septic shock is due to increased HR that leads to increased CO which therefore decreases filling time that results in decreased SV. Hence given the equation EF= SV/EDV, it goes down.
    Warmest Regards,
    Roman

      +brudforce co in late sepsis goes down because of chemokines and acidosis. Ef Goes down. Hr probably goes up

    This is a great and clear explanation. I have a question from a paramedic student point of view. You list the major indices for distinguishing between the different types of shock as the PCWP and the JVP; how would a paramedic in the field distinguish between cardiogenic and hypovolemic shock? Thanks!

    Good lecture. Have been suggesting my nursing school have a separate workshop on shock. In clinical practice, wondering how often we would have immediate access to JVP and PCWP measures as those are key features of the differences between. IS there time when shock sx appear to get those pressures? From my readings, other key features, easily readable, early visible signs of any shock would be rapid respirations, thready pulse. Tachy, tachy, hypo. Yes? I'll look at the EGDT to see if its the same for all three.

  • @davidaustin6962
    @davidaustin6962 6 ปีที่แล้ว +4

    Summary: Hypovolemic - not enough blood to go around so heart works hard, so LA and RA go up. Cardiogenic - heart becomes too weak (example, from hypovolemia) to pump blood, so LA and RA go down. Septic - the endothelium (the on/off ramps of the arteries & veins) is too sick to properly pass blood components so they dilate, so LA and RA go down, but skin temp goes high. (LA=Left Atrium pressure, RA = Right Atrium pressure).

  • @akulapardahaga

    • @LA_Viking
      @LA_Viking 6 ปีที่แล้ว

      kareb: Back in the late 1970’s-early 80’s while undergoing paramedic training, we were taught numerous types of shock: circulatory (hypovolemic), cardiogenic, anaphylaxis that you mentioned, septicemia, neurogenic shock, psychogenic shock...I cant even remember them all!
      About 15 years later I’m working on a Ph.D. In Epidemiology and I found that many “shock modes” had disappeared. I retire next year and I intend to get back into the paramedic field and it’ll be interesting to see what they’re teaching that “week.”

Since, CO is the volume of blood being pumped by the heart in the time interval of one minute and EF is the volume of ejected blood by the heart in one cardiac cycle (heart beat).

    this is great, loving it. In septic shock due to an infection causing a release of histamines, leukotrienes, cytokines, and other bad stuff inside the blood vessels. The blood vessels dilate and become inflamed, leaky, and permeable to water causing a decrease in blood pressure.

    • @Medcram
      @Medcram  9 ปีที่แล้ว

      DuePancho EF typically goes up with initial rise in sympathetics. Then, the EF typically goes down if and when the sepsis decompensates and pH drops.
