Importance of performing a quality CPR
Cardiorespiratory arrest is a sudden and unexpected interruption of the electrical and / or contractile activity of the heart, potentially reversible, which requires early treatment as it leads to the death of the person quickly.
The importance of cardiopulmonary resuscitation
For this reason, early recognition of this situation is essential to start performing basic life support. Basic life support is a series of techniques that are intended to replace cardiac function and lung function with basic means such as hands and mouth. It is a series of very simple techniques that can be performed by any type of person, age, and especially that does not require specific health knowledge. Thoracic compressions will be performed with the hands and rescue vents will be performed with the mouth.
Cardiopulmonary resuscitation maneuvers
With these simple maneuvers, the aim is to maintain manually the contractile function of the heart in order to maintain blood perfusion at the cerebral and coronary level and thus keep these organs oxygenated for as long as possible so that when Arrive the emergency medical team can restore the organized heart rate and decrease the neurological and cardiac sequelae and therefore the quality of life and survival rate.
In previous articles the chain of survival has already been mentioned, although we will proceed to explain it briefly to understand the concept together.
The survival chain is a series of four links necessary for successful resuscitation.
1. In the first place is the early recognition of the situation, in order to assess some situations that may lead to cardiorespiratory arrest and act as quickly as possible.
2. The second link is cardiopulmonary resuscitation by witnesses quickly. For every minute without doing cardiac massage, the chance of survival decreases by 10%. The early onset of these compressions can double or quadruple this survival rate. In this link the objective is to replace the cardiac function.
3. Rapid defibrillation is in third place in order to get the heart into an organized rhythm and therefore recover the circulation of the affected person. It can have survival rates as high as 50-70%. Here it is intended to restore cardiac function through an electric treatment.
Finally there is the advanced life support by the medical emergency team and transfer to a useful health center that allows the optimal recovery and treatment of the person suffering from a cardiorespiratory arrest. This link is intended to restore cardiac function through electrical and pharmacological treatment.
Following the chain of survival it is essential that the greater the number of people who enjoy this knowledge in basic life support, the better we can solve these types of situations and with greater guarantees for the person who suffers a cardiorespiratory arrest.
From the moment we activate the survival chain alerting to the situation that is happening, until medical assistance arrives, there may be a period of about 6-11 minutes depending on the city we are in, these minutes can increase if we are in rural settings Therefore, it is essential that witnesses who witness a cardiorespiratory arrest have the knowledge and good technique when it comes to making compressions in order to keep that heart with “life” until the arrival of the definitive help. It is recommended that an adult, just detect that you are in a situation of cardiorespiratory arrest, ask for help and without wasting time start doing cardiac massage.
Chest compressions and survival chances
The explanation for this is for the following, just at that moment, the blood of the organism that stops being oxygenated and endures several minutes like this, hence the importance of a quality massage, so that that oxygen can continue to reach the heart and brain and can maintain their functions without damage to their structures.
The correct technique to perform the compressions, according to the European Resuscitation Council Guide, indicates that the person has to be on a rigid surface and face up. The person who performs the compressions should be placed on the victim's side. You should discover the chest in order to locate the point of application of cardiac massage.
The cardiac massage will be performed in the center of the patient's chest, in the lower third of the sternum, interlacing the hands and with the straight arms and at 90 degrees with respect to the patient's chest.
How are chest compressions performed correctly?
To perform the CPR maneuvers we will drop the weight of the body on the patient's chest, sinking it between 5-6 cm at a frequency of 100-120 compressions per minute. After each compression is important that there is a good decompression, so that the heart can be completely filled with blood. Avoid reducing pauses between compression and compression no more than 10 seconds.
We will follow a sequence of 30 compressions followed by two rescue vents. We will continue this technique until the patient obtains signs of life, the medical emergency team arrives or until we are exhausted.
Smart defibrillators with "push harder" auditory indications
There is currently a defibrillator model on the market, Zoll AED 3, which implements a system called "Real CPR Help", unique in the defibrillator market. It allows us to perform chest compressions in the most effective way, since it communicates to the resusciters if they are doing the compressions with the most effective depth and frequency. It offers visual and auditory indications to press harder or informs them when they are performing correct compressions.
