What are the symptoms of cardiac arrest? How to first aid cardiac arrest? After cardiac arrest, the most prominent is deep coma and palpable arterial pulse. It can be divided into four stages: cardiac arrest, cardiac arrest and cardiac death. The symptoms of cardiac arrest include the following aspects
Cardiac arrest symptoms: sudden syncope, loss of consciousness, limb convulsions and other cardiac arrest symptoms.
The heart stopped for 10-15 seconds. As a result of cerebral anoxia causes fainting, loss of consciousness, the patient can suddenly fall from the sitting position, standing position, shouting no response. At the same time, facial and limb muscle convulsions, as long as a few minutes.
The second symptom of cardiac arrest: sudden disappearance of heart sounds, pulse and blood pressure.
Observe the pulse to the main artery, adult to carotid artery, femoral artery, children to brachial artery.
The third symptom of cardiac arrest: respiratory arrest.
The symptoms of cardiac arrest are as follows: intermittent or sighing at the beginning, only a few breaths per minute, small breathing movement, no signs of chest fluctuation, and soon the breathing stops completely. Respiratory arrest usually occurs within 20-30 seconds of cardiac arrest.
Symptoms of cardiac arrest four: mydriasis, light reflex disappeared, cyanosis.
Cyanosis is a sign of cardiac and respiratory arrest. Cyanosis, mydriasis and light reflex disappeared in 45 seconds after cardiac arrest. Mydriasis was fixed in 1-2 minutes. Cyanosis can be seen in the facial skin, lips, nails and other places into purple black.
Based on the two important symptoms of cardiac arrest, deep coma and palpation of the great arteries, we can judge whether the heart has stopped suddenly and start rescue immediately. To judge whether cardiac arrest, do not rely on the stethoscope to listen repeatedly, let alone use the electrocardiograph to judge. Because after cardiac arrest, the relationship between the start of resuscitation and the survival rate is very important, we must seize every minute. The basic life rescue is mainly chest compression and artificial respiration, the purpose is to provide the minimum blood supply to the brain. For further life-saving, it is necessary to use instruments and drugs, such as endotracheal intubation, DC asynchronous defibrillation, epinephrine, atropine and other drugs to facilitate the recovery of heart beat.
After reading the above content, you should have some understanding of the symptoms and first aid methods of cardiac arrest. Today we will introduce the symptoms and first aid methods of cardiac arrest. More topics about heart health will continue to be introduced in the following articles. Welcome to check.
