You're videos are absolutely phenomenal! I cannot stress this enough. Thank you so much for the work you are doing.
This is great. Really helping me study for my RN Exam tomorrow. Khan Academy always to the rescue 🙏🏼🙏🏼
Thank you for videos!
I've read in one book that in the neurogenic shock there are at first bradycardia and big CO, but after some time there is a tachycardia and small CO... I'm confused - can you explain me these things? Are they true?
Totally awesome explanation ! ! Thank you! :)
In lecture today, my professor cited PALS and said that in all the shocks [obstructive, cariogenic, hypovolemic, & distributive (anaphylactic, septic, & neurogenic)] the BP is not like adults meaning that the pediatric patient can compensate (due to a healthier heart)and maintain a normal BP while in the compensatory phase of shock, then switch into a low BP once not being able to compensate anymore. All that makes sense, except in neurogenic shock, because the SNS compensation ability is enabled, so how can there ever be a normal BP in neurogenic shock for a pediatric patient? I asked what makes a pediatric patient with a SCI experiencing neurogenic shock different than an adult patient in regards to BP, and I was told that the child can compensate better than an adult. After asking again how that can be without a functioning SNS I was then told it depends on they type of SCI and if the child was decapitated.
So, I am at a loss, please help!
This helped me to understand and separate neurogenic shock from the other shocks I'm reviewing
That was so helpful. Thank you so much!
Thank you so much for this video, really fills in the gaps on my terrible textbook explanation
Thank you so much! the patho really helped break it down for me!
great video, made it very easy to understand neurogenic shock
Many are left with no info on this and the sequence before and after. Excellence info and much thanks.
Amazing explanation!
You guys are awesome! Thank you!
s/s for neurogenic shock must be observe all the time, check vital signs, prn medications must be available at bedside, physicians tel. number/mobile number must be visible (on the wall ) for emergency tel. orders, 02 at bedside, maintain a quite environment, npo, emitional support and other related nursing intervention
The Heart rate is controlled by the nervous system which controls the firing rate of the SA node. From my previous readings I knew that the firing rate of the SA node is 120 bpm but what makes the heart rate less than this number is the fact that the SA node is under the control of the vagus nerve so if we lose nervous control of the heart the heart rate should increase not decrease. Am I wrong? Please explain this point and thank you very much for your great videos
I always thought the SA node worked independent of the nervous system, and that's why it continues to pump outside the body. A little confused by how susceptible the heart rate is to neurogenic shock
Ghada Karim spinal shock is mainly due loss of sympathetic tone that is thoracolumbar outflow but meantime when sympathetic is blocked parasympathetic becomes unopposed so Brady will b there
Great explanation!
Great explanation!
Great explanation !
You guys are life savers!!!!!!!
Great video, thanks!
Thank you! that was great!
You're Awesome! Thank you!
I wonder if adrenalin (epinephrin) could be used as a treatment regime for neurogenic shock
+tshepo dibotelo yeah it is used.neurogenic shock leads to depression of sympathetic system which leads to loss of SVR. Sympathomimetic drugs includes epinephrine , norepinephrine etc which increases vascular tone and promote better perfusion .
Great video. Can someone explain why the body would respond to atropine but not the sympathetic nervous system? I am a little confused, if the nervous system is shut down as you said, then why would it respond to atropine? Is it just because atropine blocks the PSN?
Fluid therapy is used cautiously because risk of pulmonary edema
Presentation in 5 min and now I'm more confident lol
Please, somebody, what do you do after a neurogenic shock?
very clear
Thank you :)
good work
U r giving IV fluids but heart is not working efficiently, won't it lead to edema?
Yes that's true but in the video he does state treating with pressors to treat hypotension from the shock, thus making it safe to administer IV fluids without risking edema.
Thank you in 2020, too 😊
Thank you!
The weak pulse that u notice in shock is due to low stroke volume and low blood volume?
no sympathetic input from the SNS
spinal injury above T6 (sympathetic chain T1-T4?)
khan i love you im gonna pray for you everyday
thanks alot you made my day and I do love this black background
Good to know
Bradycardia is a sign not a symptom
why it happen just T6 level or above ???
sympathetic outflow occurs from T1 to L2/3, this means that if there is a transection around this point the sympathetic innovation will be lost and wide spread vasodilation occurs
I like your voice :) lol good explanation thanks~
why am i watching this im in the 8th grade lol
And as it is appointed unto men once to die, but after this the judgment: (Hebrews 9:27)
And the times of this ignorance God winked at; but now commandeth all men every where to repent: (Acts 17:30)
For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death. (2 Corinthians 7:10)
I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:5)
For whosoever shall call upon the name of the Lord shall be saved. (Romans 10:13)
