Statistically, there are approximately 700,000 cases of cardiac arrest in Europe per year. Only 5-10% of them survive transfer to hospital. Early defibrillation and rapid (within 1-2 minutes) resuscitation can result in 60% survival.
Cardiac arrest (infarctus myocardii) is an irregular heartbeat, which can be characterized with no pulse or ventricular fibrillation. It is characterized by the agonal respiration (wheezing) or a full stop breathing and loss of consciousness. A cardiac arrest that lasts longer than 5-10 minutes can reverse hypoxic brain damage and also drastically reduced chances for reactivation of the heart.
The purpose of basic life support and use of automated external defibrillator is:
– Early recognition and call for emergency medical help
– Early implementation of basic measures for resuscitation (BLS), “buying time”
– Early defibrillation, reactivation of heart
– Early implementation of measures for continuing resuscitation (ALS)
The purpose of basic life support is to start with early resuscitation until a professional team arrives to take over the patient and transport him to an appropriate facility. The main goal is to enable non-medical persons to perform chest compressions (massage of the heart), which is also the main goal of resuscitation, enabling circulation.
Guidelines and recommendations for proper chest compression:
– Place the palms of your hands on the center of your chest
– Place one hand on top of the other
– Cross your fingers
– Chest compression
– Frequency of 100 min-1
– Depth of 4-5 cm
– Allow the chest to rise again
– The person doing the compression should be changed every two minutes
The automatic defibrillator is a device that can independently analyze the heart rhythm and recognize whether the heart needs defibrillation or not, that is, it can also be used by non-medical persons, which is actually its purpose. It is important to note that basic life support and the use of the external automatic defibrillator can also be applied by non-medical personnel.
