All cardiac arrests need quality compressions
The message is clear early defibrillation saves lives, anyone with a minimum of training could use an automated external defibrillator (AED) and if used in the first 3 minutes after a cardiac arrest increases the chances of survival in more than one 70% ( ERC 2015).
Using a defibrillator is very simple, but is it just as easy to perform quality compressions, being these vital? Does the defibrillator that you have already purchased or are you planning to purchase really help you perform quality compressions? Let's talk about quality chest compressions today!
Quality Cardiopulmonary Resuscitation (CPR)
After a cardiac arrest you have to call the 112 and start the CPR, start with the chest compressions, to circulate the blood through the vital organs such as kidney, brain and heart. The compressions must continue until the arrival of the defibrillator or the ambulance.
Well aside from circulating blood throughout the body, we seek to circulate the blood by the own heart of the victim to maintain irrigation in these cardiac cells in order to continue receiving nutrients and remain electrically active until the arrival of the defibrillator.
To get good quality compressions or quality CPR you have to compress with a frequency between 100-120 per minute and a depth of 5cm and no more than 6cm (this is very difficult if you do not have practice)
When the automated external defibrillator (AED) arrives
When placing the defibrillator on the patient, he will make a diagnosis every 2 minutes and 2 assumptions may occur:
-Option A: Advise electric shock (shock) and tell us to continue with the compressions.
-Option B: Do not advise electric shock and tell us to continue with the compressions.
As we can see there are times when there are no electric shocks because the person's heart does not have a chaotic arrhythmia that requires electric shock. However, what is clear Both option A and option B have to perform quality compressions.
The defibrillator every 2 minutes back has made a diagnosis in search of the chaotic rhythm to give or not, an electric shock. In between we must continue with the quality chest compressions until the arrival of the amabulancia.
We can conclude that not all cardiac arrests they need an electric shock at the beginning, but they need at all times quality chest compressions (100-120 rhythm compressions per minute and depth of 5cm and no more than 6 cm)
Girona Cardioprotected Territory (study of defibrillators)
In Girona, a recent study on the use of defibrillators in public spaces from the 2011 until June of 2015. Complete information has been extracted from some 188 of the 233 defibrillators used. In the conclusions, we can observe that the asystole (non-shockable rhythm, which does not need electrical discharge) was the rhythm that most appeared in the cardiac arrests (42%), while an 23% of the rhythms were ventricular fibrillation, where the defibrillator successfully treated half of the patients who had a shockable rhythm.
As we can see, in the 100% of the cardiac arrests (188), it is necessary to perform quality chest compressions. Therefore, it is important that the defibrillator not only tells us whether to discharge or not, but also that we were guided throughout the process of cardiopulmonary resuscitation, indicating the appropriate rhythm and depth (5cm and no more than 6cm)
Does your defibrillator indicate the quality of compressions?
From the lifeguard project we offer a wide range of defibrillators, including the defibrillator exclusively Zoll, who have incorporated the Real Help technology to the CPR and through a device that is between the electrodes, tells us by voice message in real time how we are doing the chest compressions ensuring that we reach those 5cm and no more than 6 cm.
Having a device that tells us with voice messages if we are performing well the compressions is very helpful in times of great emotional stress. With the Zoll defibrillator we make sure that we adequately comply with the links in the survival chain throughout the process of cardiac arrest.
CPR and DEA save families. We have to start being more demanding when purchasing a defibrillator and look for those that provide us with a full help for non-health rescuers.
When choosing a defibrillator, see if it will really help in all cases of cardiac arrest both option A or option B discussed above. If you already have a defibrillator that does not have help for CPR, we offer it to you in a plan renove to update your defibrillator.
A strong hug Lifeguard!
