Can you do a video series on ABGs and different diseases or what you might expect to see? You are an extraordinary teacher and the drawings really helped to understand anatomy and physiology!! I went to nursing school 13 years ago, but have been in critical care the last year and we have been lacking classes because of Covid so thank you so much for creating these videos!!!

[@creditrepairwizards]

QUICK ANSWER VV Lungs only VA heart and lungs The primary difference between the two is the way the ECMO circuit is connected to the patient’s circulatory system. In VV-ECMO, the circuit is connected in series to the heart and lungs, which means that it only supports the lungs 12. In contrast, VA-ECMO is connected in parallel to the heart and lungs, which means that it can support both the lungs and heart 12. Another difference between VV-ECMO and VA-ECMO is their respective indications. VV-ECMO is typically used for patients with isolated respiratory failure, while VA-ECMO is used for patients with cardiac failure or combined cardiac and respiratory failure

My father had COPD and Heart failure isssue. Heart failure issue increased always due to Stress. My father got covid 19 and with oxygen supplement it was 76-78% saturation. As he had COPD and Stress related ( broken heart syndrome) then why they choose still ventilator instead of ECMO. When putting ventilator they forcefully some nurses and doctor also scrim at him and also my father and they bind both hand to give more stress. Within 1 hour putting ventilator he died. I was aware about ECMO but not sure what machine it was. I was all time feeling that he will be ok if that machine has been put on him. Those doctors and nurses killed my father.

This is so helpful. My dad is on VA ecmo, CRRT and a ventilator after having covid, and is waiting for a double lung and kidney transplant. Watching your video somehow eases the fear. I would love to know why might VA ecmo need support via ventilation? (first year med student just trying to understand things!)

[@ICUAdvantage]

I'm so sorry to hear about your dad Asthma. I really hope things have turned around for him since this comment. As for VA needing support from the ventilator, it all has to do with the blood that is not going through the ECMO circuit. Some still follows our normal blood flow pathway through the R side, lungs and L side of the heart. Now, depending on the amount of cardiac activity, this blood is being ejected in to the aorta and is being used to supply oxygen to the first few branches off the aorta (going to the upper body, and more importantly the head) as well as the coronaries. If the patients lungs are working great, then minimal vent settings would be needed. In theory, you could go without. But, if the function of their lungs begins to decline, we risk having desaturated vital blood supply to the brain and heart. Hope that makes sense.

[@rachi4346]

Excellent video!!!!!

[@Djellal]

Great lecture! Thank for all you do first off. There is something that I'm trying to grasp though. If VV ECMO is to help the lungs that are affected, why do we return the blood to the RA via the superior vena cava, instead of returning it to the pulmonary vein that actually carries oxygenated blood once its leaving the lungs? Isn't that a way to bypass the lungs without compromising the gas concentration in the blood? Aren't we having oxygenated and deoxygenated blood mixed up in the RA?

[@ICUAdvantage]

Great question. So accessing the pulmonary veins would be quite difficult, especially compared to the SVC/IVC/RA. And the goal with VV ECMO is to provide a large quantity of oxygenated blood. Doing so in the RA, still ultimately supplies to same amount of oxygen to the pulmonary veins and beyond as if we just returned there directly. Essentially we have easy access and return and we are providing this oxygen into the system before it makes it way to the rest of the body, which is our end goal. And yes, we do have mixing of oxygenated and deoxygenated blood, but this doesn't change the amount of oxygen we are actually delivering which is our big contributor to oxygenation and perfusion in these patients. Their lungs at this point are providing very little gas transport so we need to take this over for them. So all in all, I wouldn't see any benefit in delivering the return of oxygenated blood to the PVs vs the RA prior to entering the pulmonary circulation. Hope that helps and thanks for watching!

[@Djellal]

@@ICUAdvantage thanks for your answer. I’m trying to make sure I got your point. You’re basically saying the mixture of oxygenated and deoxygenated blood is not an issue, once blood is returned in the RA, because the systemic blood flow is still receiving oxygenated blood, and therefore meeting the end goal of VV ECMO. And lastly, you’re saying that we aim for the RA as the return site because it is more easily accessible and more compliant to receive a larger amount of blood compare to the PV?

[@PREDATOR0140]

Hi. I`m an ICU nurse for 7+ years now and our cardiothoracic surgery ICU has used ECMO for the second time.(it`s quite new technology for Romania where I practice).So we had a severe MI patient with VSD developed post MI.The surgeons managed to patch it up but he was in post op cardiogenic shock with massive amounts of epinephrine and norepinephrine and dobutamine.They decided to put him on VA ECMO as a last resort.As we are pretty new to ECMO we couldn`t figure out why the patient still needed massive amounts of pressors even thou he was on relatively high flows on ECMO.(he had femoro-femoral acces).Instead of droping the pressor rates we needed to rise them.Eventually he died.But I couldn`t figure out why it didn`t help him at all.Can you give a hint?also I would love to find out how you anticoagulate your patients on ECMO.With heparin you monitor ACT or APTT?what are the target values?(for a patient with no bleeding risc). Thank you very much!Your content is amazing!

[@ICUAdvantage]

Sounds like a disaster of a patient to care for. Unfortunately, ECMO doesn't always fix people. While you are correct in assuming that usually, especially in cariogenic shock, hypotension is a result of insufficient cardiac output, and thus when VA ECMO is started, we provide that perfusion for the patient and they should have a normal MAP. Unfortunately, other factors also go in to determining our patients perfusion and a big component of that is our vascular resistance. Given the patient sounded very sick by the time ECMO was initiated, I would image they have massive vasoplegia going on, and probably already down an irreversible path of inflammation, endothelia damage, and other factors contributing to massive vasodilation. Obviously only my guess having not been there. As for anticoagulation, we shoot for 180-200 ACT goal for VA ECMO. We often also use TEG to analyze the coagulation profile. I will say, because of the anticoagulation and general state of imbalance in the body for these sick patients, bleed in some form, is almost always an issue.

[@PREDATOR0140]

@@ICUAdvantage so you use ACT if favor of APTT? asking this because from what i red, APTT is more commonly used.We also use APTT on CRRT procedures.

[@ICUAdvantage]

@@PREDATOR0140 We have the iStat at the bedside and its quick and easy to use. We do run standard coags too but base titrations off bedside ACT.

[@tenzinnnn2776]

My patient is on VA ecmo cannulated in the right fem both drainage and return. Why is her right leg only so swollen?? and the pulses still present for both.

[@ICUAdvantage]

Couple initial thoughts... 1) Are they bleeding in their leg? How have their H/H levels and MAPs been? 2) Did they use a cannula for the return or a graft? We would see this with grafts where there was so much perfusion going down the leg (opposed to flow often being restricted by the cannulas) that they would swell up. 3) Warm and swollen or cold?

[@tenzinnnn2776]

@@ICUAdvantage thanks for the quick response. The patient had been receiving daily units of prbc. Heparin turned off for 2 days due to bleeding from the insertion site. There was a feeder cannula with good flow with doppler. Leg is also warm to touch. I guess and ultrasound would help to rule out if any occlusion?

[@JanellCouture]

I do have a question about VV ecmo and anticoagulation. I think you said that we are less worried about clots post oxygenator as it will be trapped in the patients pulmonary circulation. wouldnt that increase the risk of PE or difficulty weaning?

[@ICUAdvantage]

Hey Janell! Great question. So typically the clots that form are going to be much smaller than we worry about with DVT and PEs. Yes, if they break off and lodge in the pulmonary vasculature somewhere, we are going to create a V/Q mismatch. That said, we are fully supporting them with ECMO. The body will naturally degrade the clot and eventually it will no longer cause this mismatch. Sure if the clot is large enough and we are working to trial off ECMO, this can pose a problem/delay, but in most cases this is not much of a concern. For VA ECMO though, this is a very different story even for the tiniest of fibrin and clots.

[@kurdishfaithfulofallah2228]

Hi please respond back we have a patient who is right now based on ecmo but we are not sure if he is alive or not because his eyes are full black not reacting on light.. My question is how do you know if the patient is dead and his heart is working

[@ICUAdvantage]

Sounds like brain death testing would be in order

[@alexkats91]

Hi Eddy how about using ECMO (VV) or (VA) and measuring the Heart function through a Swan - Catheter? Does it gives a realistic CO?

[@ICUAdvantage]

Great question. VV ECMO should have no real impact on hemodynamics and thus your SWAN will remain true. For VA ECMO though, we are offloading the heart and returning blood after the heart. We are doing much of the role of the heart and thus the SWAN isn't going to give us accurate CO. In reality, it should be very low CO as our goal is to rest the heart.

[@JimmyArcher-m4s]

[@matthewcourtney-jones6041]

will their BP drop because of the extension of the vascular circuit?

[@ICUAdvantage]

Great question Matthew. Ideally no, as the volume we remove is replaced. The tubing is all primed with fluid so as we take the blood out initially, it is immediately replaced with the same volume of fluid. That said, some patients do drop often as a reaction initially to the circuit, hence why it helps to have pressors and fluids primed and hooked up ready to go just in case.

Fascinating!

Thank you very much !

[@ICUAdvantage]

You're welcome! 😊

[@neeteshagrawal37]

For vv ecmo what is the act range

[@ICUAdvantage]

It honestly truly depends. Classic anticoagulation is defined as ACT of 180-220, but oftentimes we can run with a lower goal for VV or even in some cases no anticoagulation so long as the circuit is running smoothly.
