High Quality Cpr: Fill & Download for Free

First, your understanding of the percentages you quote is horribly flawed, and likely beyond this venue or my time to correct.That said , let me correct some misconceptions:First:“Chest compressions do massive damage to the body and can sometimes make things worse.”This is patently false. Period.Even if the patient has a pulse, CPR will not damage the heart . The most common complications, breaking the ribs, are mild in comparison to the alternative. The only things that make things worse is “poor quality chest compression” because they are wasting a narrow window of opportunity to successfully resuscitate a patient.Second:The window of opportunity for an AED to be effective alone (which appears to be your contentions) , is only in the very first 2.5–4 minutes of arrest, if at all.The benefits of CPR, early notification of EMS, and the AED are all commutative and subject to many many variables, but perhaps the most easily understood is TIME. Using TIME as a construct, we can break the phases of resuscitation into three basic phases: Electrical, Circulatory, and Metabolic.//————- Time —————————————→This graphic represents the period where the heart has the most ATP and is most likely to respond to an AED shock, to the period when ATP is almost completely exhausted and therefore the heart is least likely to respond an AED shock.It is possible with high quality CPR (and only high quality CPR) to move a patient from the right side of the chart to the left , increasing survival. This is because high quality CPR helps restore ATP in the heart itself.There is a ton of research on this topic, specifically showing that high quality CPR improves the chance of successful shock and survival. The inverse is also true. Poor CPR makes it worse, as does doing no CPR.A good overview is here:-Steve

I can assume by the wording of this question you’re not in EMS. Therefore, I don’t know where in the hell you’re getting Epi, but that’s beside the point. If you aren’t in EMS, you don’t know the indications and contraindications of Epi and don’t know its other reactions, so you shouldn’t use it.High quality CPR and early defibrillation are key to surviving cardiac arrests. If you see an adult or teen suddenly collapse, push hard and fast in the middle of the breastbone at a rate of at least 100x per minute. Repeat until help relieves you. Call 911! Do not give the patient anything, including meds, food, or water.

There is a defined protocol for basic and advanced CPR but there isn’t a protocol or a timeline that doctors follow to pronounce a person dead. The decision to quit CPR is based on sound judgement that comes with experience and a thorough understanding of human physiology.Coming to the second part of your question, let’s understand some facts —Defibrillation is not indicated in all scenarios involving cardiac emergencies. For example, if heart has come to a complete stop and has no electrical activity, defibrillation will be of no use.Defibrillation, contrary to popular belief, does not restart the heart. It, in fact, stops the heart for one second when shock is delivered.The way it works is, when the heart’s electrical activity is going haywire, delivering a shock momentarily depolarizes all cells in the heart (in layman words, brings all cells out of erratic activity and on to the same page) and allows the normal rhythm to take over.ATP equals energy. All cells require energy for various metabolic processes.Now, when a person goes under cardiac arrest, in the initial minutes, the cells are not dead yet. They are in a ‘stopped state,’ so to say, but not dead.Giving early, good quality CPR is central to patients’ survival because CPR involves chest compressions that ensures blood flow (therefore, ATP/energy) to different important organ systems.If the heart responds and comes to one of the two shockable rhythms (namely ventricular fibrillation or pulseless ventricular tachycardia), defibrillator will be used. If not, high-quality CPR will be continued.But CPR is not magic. The longer the heart remains unresponsive, the level of ATP/energy in the cells of the heart (and everywhere else in the body) starts plummeting rapidly.There comes a time when the levels of ATP is so low in the cardiac cells that even if a defibrillator is used, the cells have no energy to respond to the shock, or in other words, the cells can no longer re-establish a normal rhythm.Using defibrillator or continuing CPR further is not going to change the ATP status. This is why, when indicated, the use of early defibrillation is very important because using it during later stages would return aystole (flat-line on the monitor) or pulseless electrical activity (there will be some electrical activity in heart but no pulse peripherally).Around this time, the doctor might run out of places to go to on the CPR protocol and suggest that the resuscitation efforts be stopped and the patient be pronounced dead.Doing CPR and defibrillation a dozen more times until the heart responds will, unfortunately, not help.This video explains CPR wonderfully (for anyone interested): HereEffect of cardiopulmonary resuscitation on restoration of myocardial ATP in prolonged ventricular fibrillation
