Risks of CPR

Submitted ⁨⁨11⁩ ⁨months⁩ ago⁩ by ⁨ReginaPhalange@lemmy.world⁩ to ⁨nostupidquestions@lemmy.world⁩

If proper CPR involves compressing the chest so much such that the ribcage might break - doesnt that breakage risks a bone puncturing the heart?

Yes, more common however is a rib puncturing a lung. Regardless, the (slim) possibility of that happening is preferable to the certain death that would happen if you didn’t perform CPR

  This. When I got my CPR training, the consensus was: if you hear or feal something crack, don’t stop. Messing up is better than doing nothing.

    Also, if you’re concerned, don’t be afraid to perform CPR on a female. Their modesty is worth a lot less than their life.

    Hearing a crack isn’t messing up. Broken ribs are common in cpr.

If your doing chest compressions to save someone who has stopped breathing there roughly a 10% chance they will survive but a 0% chance if you don’t So it’s often worth it anyway.

However it does keep the blood flowing and can prevent brain damage until a defibrillator is available which has a much higher chance of saving someone who has stopped breathing.

  Doesn’t the defib stabilise the heartbeat rather than getting it going again?

    Yes if the heart has flatlined completely then it won’t be started again by AED. But if they are in cardiac arrest then the heart rate is erratic and can be returned to normal with a defibrillator.

    Yes, a heart that has completely stopped beating cannot be restarted by defibrillation. It only works in a condition called ventricular fibrillation, when the muscle fibers of the heart are still contracting, but are no longer “in sync”. This causes the heart to twitch chaotically, which is not an effective way to pump blood. And without blood pumping, the heart itself does not receive any oxygen as well, so it will eventually go into a complete flatline after a few minutes of untreated ventricular fibrillation.
    
    The electric shock helps the fibers resynchronize. If you want to see the effect directly, here’s a video:

    Be warned, it shows an open chest and an exposed heart, most likely during heart surgery. They are using spoon-shaped internal defibrillation paddles. In the beginning, you can see the heart in ventricular fibrillation. It’s twitching chaotically and not pumping any blood. After defibrillation, it starts contracting rhythmically again.

    Yes. Defibrillator is useless if you’ve stopped breathing.

So I’ve done lots of cpr. First off it’s kind of a misconception that you’ll break ribs from cpr. You are more likely to break cartilage than actually break bones and appropriate cpr isn’t going to break bones unless they’re the smallest most frail person and the individual doing cpr is going crazy doing compressions.

Even if you break ribs you’re probably not going to have a displaced rib fracture as there’s muscles and tissue holding those bones in place, it’s pretty rare to have ribs break so bad they risk puncturing organs and it usually involves catastrophic trauma, not what you get from cpr.

  I have, thankfully, never done CPR live, but I’m certified to teach CPR by the Danish First Aid Council. So I have a interest in learning from actual practitioners, although I’m obviously not allowed to alter the course.
  
  Where do you stand on ventilation? Currently I have to teach 30:2 mouth to mouth, but I know that there’s talk about skipping ventilation either entirely or at least for adults. The thinking being that children don’t suffer spontaneous cardiac arrests, but that it’s usually a result of blocked airways.
  
  Do you do ventilation and does it make a difference in your experience?

    I’ve had a few different First Aid courses and the instructors all have slightly different reasoning. One argument for compression only is potential for passing disease mouth to mouth, the newer courses tend to teach this because sometimes people that don’t feel comfortable doing rescue breaths will fail to do CPR at all. Another is that in cases where you’ve witnessed the event, the blood is already fairly well oxygenated and if medical help has a good response time the benefits of breaths are minimal. The first is more about compression only CPR being better than nothing, breaths are still advised where the rescuer feels comfortable doing so. The second is pretty situational.

    CCR is the primary method taught in cardiac care. E.g only compression. This is because the primary issue is preventing clots and making sure you get some blood flow to the tissues. Full oxygenation isn’t as important due to lower oxygen demand of an unconscious person.

    So it depends on the setting and patient. Kids tend to have respiratory causes of cardiac arrest so the focus is more on airway management and positive pressure ventilation. Kids don’t generally code just out of nowhere like say a 90 year old might keel over. There’s usually a specific cause and if you can correct that cause they will rebound.
    
    As for adults it’s about the setting. Outside of the hospital we should be teaching cpr only. Especially for lay people. It gets too complicated and they’re too stressed out to remember 30 and 2, 15 and 2. Plus most people have a reserve of air in their airway and lungs that gets circulated with compressions so focusing too much on trying to get breaths in causes too many delays and confusion.
    
    Now for ems you can debate whether they should do cpr only with a non rebreather, a bls airway and bagging, a biad, or a definitive airway. It hugely depends on your protocols, provider availability, and who the patient is.
    
    In hospital we are almost always going to secure the airway during a code to remove that from the equation. We have the resources and it can be done relatively quickly without the need to delay cpr for more than a pulse check in many cases.

Dude if my heart’s not beating, by all means, break my ribs. Broken ribs are better than being dead.

You need to always remember that the patient in such a situation is at the lowest possible point. You cannot make “dead” any worse. So “risks” don’t apply in that moment.

Or, as a paramedic I knew said when someone asked him about the same question: “Whatever happens, it won’t kill him”

You can’t do more harm than dead is the idea.

Dark healthcare provider humor incoming: When considering these kinds of questions regarding CPR, we actually say, “Well, they ain’t getting any deader.”

CPR actually reverses death. That’s why it only works sometimes and only if provided in a very short window of time after you’ve died. Nothing that is done during CPR is going to make that worse. So yeah, the reality is that it’s a little bit of a controlled free-for-all. It’s called “heroic measures” for a reason.

While we’re on the topic of CPR, I want to address the myth that CPR “almost never works”. It’s great at what it does, which is pumping blood through the body enough to keep vital organs supplied with a bare minimum of oxygen so they can survive.

However, there’s usually a reason why the heart has stopped beating and in most cases, CPR can’t reverse that reason. If the patient is in a car crash and has completely bled out, CPR won’t get any blood back into their system. Or if they’re at the end stage of a terminal disease, CPR can’t magically cure the disease.

But in cases where the cause for the cardiac arrest is simple and easily reversed, chances of survival are much higher. For example, if someone is drowning and you get them out of the water within a few minutes of cardiac arrest, CPR is very effective, with the majority of patients surviving. Here’s a study with 113 patients who were resuscitated after drowning and only 8 were confirmed dead. For 20 patients, the outcome was unknown, but even if they all died as well, that’s still a 75% survival rate.

  It’s not that CPR doesn’t work, it’s that outcomes after resuscitation usually aren’t great. The study doesn’t disclose ages or neurological outcomes post-rescuscitation so that limits my interpretation but quick rescue and quick CPR is key in those acute, single reason emergencies. That isn’t to say in an emergency situation you shouldn’t try especially since you don’t know that person’s wishes. There are good outcomes but usually for underlying healthy people who had one thing go wrong. Think the athlete who’s heart stops on the field for some reason.
  
  I’ve admitted at least a thousand people into a hospital through the ER and I tell everyone that it’s not like on TV. If you’re older, sick, multiple chronic diseases, don’t take care of yourself, etc. the chances of any kind of quality of life after CPR is limited. Death is terrifying and I understand them wanting to try but it’s just not realistic a lot of the time. We need better deaths in the US and more in-depth end-of-life conversations with our patients. That should be starting in the PCP’s office. Trying to discuss that with a patient in the ER who’s already scared isn’t ideal. I’ve seen patients with do not resuscitate/do not intubate orders on file change their mind when they’re suffocating and panicking then once they’re more stable immediately change their mind back.

Let’s analyze it this way.

Risk of dying from a lack of blood flow. 100% Risk of dying from a punctured heart from CPR. <100%

Do CPR. Get training. Most of the time, what you hear is cartilage popping.

  You do in fact break bones if you’re doing it right. Think of it this way, if you’re doing CPR, the patience is already dead, nothing’s worse than death, so bringing them back in whatever condition is going to be better than what condition they’re already in, which I may remind you, is death

    I would argue that ‘any condition’ isn’t really better. If they return as a vegetable, wouldn’t their loved ones ultimately rather remember them as they were before, instead of wiping their shit for a miserable decade?

The person is dead if you don’t do something. You cannot fuck their day up any worse than it already is.

Don’t think about it, just act!

Make sure that you are safe.

Get emergency services on the phone.

Get going with 30:2 at 100-120 BPM.

Get some help from the people around you. Send someone for an AED.

You can think about it later.

  And to make things clear for people who don’t know it’s 30 compressions, 2 blows of air. For very young children it’s faster though, 15:1.

  - BigDanishGuy@sh.itjust.works ⁨11⁩ ⁨months⁩ ago
    Depends on the material, I have to teach 30:2 so that people don’t freeze. There’s a special course for people who are responsible for children, they learn a different algorithm, but I haven’t taught that course, so I’d have to read up on it. I believe that it’s still 30:2, but with 5 blows initially.
    
    So I guess, just do 30:2 and don’t worry about the age part.

I suppose, but the risk is low. Especially if your only other choice is to die in a minute without CPR.

notapantsday@feddit.de ⁨11⁩ ⁨months⁩ ago
I’ve never heard of a punctured heart personally, but I do think it’s possible. A punctured lung is much more common. But both conditions are usually treatable if the patient survives.

CPR does carry some risks, but not doing CPR is guaranteed to be lethal. So any risk (to the patient) is worth taking at that point.

  I fucking hate the baby dummies. Luckily I don’t have to use them when teaching, as I’ve never taught a course for people with a special responsibility for children. But I still shutter when I encounter one in the dummy depot.
  
  Adults? Sure, we’re all going to die some day. Kids and toddlers? Nope, no thank you, no way.

Training (and presumably the Emergency dispatch) tells you exactly where to put your hands to minimize the risk of anything catastrophic happening because of your effort. You probably don’t need to worry about broken bones; in fact, the sound of bones cracking a bit is a sign that you’re pushing deep enough to actually compress the heart and pump some blood.
