Carbon Dioxide & Intracranial Pressure (ICP): Effects of CO2 on blood vessels.

A short animated video covering basic concepts in CO2 management in patients with a raised ICP.
Why do raised co2 levels lead to the dilation of blood vessels?
How can we manipulate this to our advantage when managing raised intracranial pressures?

Thank you! i was always confused on how CO2 was a vasodilator leading to hypotension in the body (decreased pressure) while leading to increased icp (increased pressure) in the head at the same time! to me they had a sort of inverse relationship but the pathophysiology broke it down for me and it makes sense now. Thanks again

Love this video! A true life-saver (at least for me). I was confused by overcomplicating things (like therapeutic hyperventilation was related to MAP blah blah). Finally able to fully understand the concepts now.

I'm currently studying paramedicine and this video made it so simple for me to understand the effects of CO2 on ICP. Thank you so much!

[jaypatel]

short sweet simple and easily understanding

[leah_slv]

This is exactly what I needed to help me understand this relationship, thank you

[alinamandani]

Thanks for conveying such an important concept in simple words!

[humma]

One of those tiny not so tested but very useful topics in conceptual approach to ICP

[Diana-chsh]

THANK YOU FOR A CLEAR AND CONCISE EXPLANATION! AWESOME

[jyprevet]

Thanks for making video.
This video is so helpful for my study!!

[skwail]

Great video! Glad I found your channel so I can check out other stuff you’ve put out :)

[joannekenyon]

Brilliant, thanks for this simple explanation,

[RigoStar]

This was extremely helpful to me. Thank you!

[isaeatsbabies]

Thank you! Quick and easy video to understand

[normaeunicechavarria]

Loved it nice and simple! Thank you!!!

[melani]

This was a very good video.. awesome!
I’m greatful that today, we have different types of ventilators, and it can keep track of how much oxygen to give a patient and how much C02 to get rid of. So many lives are saved because of it. Goc bless 🙏

Love the info! Would really appreciate if you slow down in speech. Thank you!

Great information! Can you add a note saying that hyperventilation is effective in in the later stages of TBI management, or if you are adequately trained and have the equipment to monitor ICP and PaCO2. In the early stages of TBI; avoidance of the 3 H-Bombs (Hypotension, Hypoxia, and Hypocapnia) is critical to minimizing secondary injury.

Thank you, that answered many of my questions.
I realise that this is not the place to ask for medical help but as I am unable to get answers through normal routes:

I have had headaches, pulsatile tinnitus and many other head and ear symptoms for 2 years now, undiagnosed. I have no vision problems. I had polio 69 years ago and, possibly as a result, my minute tidal volume is low, I believe about 2 litres. I have managed all my life, oxygen levels seem fine. I wonder whether, with old age (72) my body is not coping now with low breathing, resulting in higher CO2 and increased intracranial pressure causing my symptoms. Doctors dismiss this and tell me to stop looking at YouTube!
I think I may be an interesting case, worthy of investigation. I am awaiting a 2nd brain MRI.

Again, apologies, I know this is inappropriate.
