According to the different diseases that lead to sudden death, it is divided into sudden cardiac death and non-sudden cardiac death. Among them, sudden cardiac death is the most common, accounting for about 75% of sudden death cases. This sudden death is caused by heart, characterized by sudden loss of consciousness, and dies within 1 hour after the onset of acute symptoms.
Although sudden death is extremely sudden, there are traces of such sudden death. Unfortunately, many people don't know that the body may have sent you a "warning" before sudden death!
These six symptoms may indicate sudden death.
Palpitation, palpitation
A few weeks before sudden death or 1-2 months ago, the patient had a subjective description, and his heartbeat was accelerated or irregular. Most arrhythmias are less dangerous, but if they are frequent ventricular cardiac arrhythmias, they are at risk of developing ventricular fibrillation, so they should be treated in time.
chest distress; chest oppression
Chest tightness is a common "early warning" signal of cardiovascular diseases, which is characterized by breathlessness and a feeling of being blocked in the chest, which is relieved after deep inhalation.
Bradycardia, less than 60 beats/min.
If the heartbeat is too slow and the blood pressure becomes low, it is easy to have long-term cardiac arrest, and in severe cases, cardiac arrest can occur.
faint
Most syncope is caused by vascular occlusion and stenosis, which leads to insufficient blood supply to myocardium and brain.
Black eyes and numbness of limbs
Stroke is also an important cause of sudden death. If you can't see things on one side, your limbs are numb and weak, or you walk unsteadily and feel like stepping on cotton, you should be alert to the occurrence of stroke, identify it early and treat it early.
Hold your breath, and your lips are obviously purple.
Suddenly I feel unable to breathe, and my lips appear blue-purple hypoxia symptoms, which is probably a precursor to sudden death caused by important vascular embolism.
Attention! These four types of people have a high risk of sudden death.
Often stay up late
Because of work or entertainment, sleep time can not be guaranteed, and the body can not rest fully, which may lead to disorders of organs, endocrine and nervous functions and induce cardiovascular diseases.
Alcoholic crowd
Drinking heavily for a long time will not only hurt the liver, but also hurt the "heart"! Alcohol can stimulate sympathetic nerve, accelerate the heart rate, lead to arrhythmia, and also induce peripheral blood vessel dilation, which will increase the heart load.
Sitting for a long time, obese people
Sitting or standing for a long time will affect the blood circulation of the body, and long-term inactivity will increase the risk of obesity, which will easily lead to cardiovascular disease and increase the risk of sudden death.
Long-term stress
Not only the body, but also the invisible serious anxiety may affect the function of the nervous system, resulting in symptoms such as rapid heartbeat, palpitation and chest tightness.
First aid for sudden death "golden four minutes"
1 minute to achieve the rescue measures in the kit, the rescue success rate is extremely high;
The rescue measures were implemented within 4 minutes, and the rescue success rate was about 50%.
Implement rescue measures within 4-6 minutes, and the success rate of rescue will drop to about 10%;
10 minutes or more, almost no possibility of survival.
If people around you have an emergency, remember that falling to the ground within 4 minutes is the prime time for first aid.
First of all, you can pat him on the shoulder, explore whether he is conscious and check whether he is sucking, and take the following two measures according to the situation:
If conscious,
Then let him lie on his side to avoid tongue or vomit blocking the airway, call 120 and wait for the ambulance;
Without consciousness
Or if you only have breathing near death, call 120 immediately, and start cardiopulmonary resuscitation at the same time, including two steps: chest compression and artificial aspiration.
Chest compression
Location: the midpoint of the connection between the two nipples;
Posture: the palms of both hands overlap, the fingers are raised, and the palms are forced. Arms stretched straight and not bent, perpendicular to the chest of the injured;
Strength: press it at least 5cm, and the frequency is100 ~120 times/minute.
Artificial sucking
Raise your head: put the injured person's head back and lift his chin;
Pinch his nose: pinch his nose with your hand;
Blowing: Blow hard from mouth to mouth twice, with each blow above 1 s, and see the chest bulge of the injured person.
Chest compressions and manual aspiration should be performed alternately, with the frequency of 30 compressions and 2 aspiration until the ambulance arrives or the patient is confirmed dead.
