If he had paid attention to this point of knowledge, his father would still be...

Today, the Lord of Disease Control tells you a story:

Mr. Li is a senior white-collar worker in a large multinational company,

to conquer a project,

eats and lives in the company office with several colleagues for several days. On the morning of the 5th day of

, after simply coping with a few bites of breakfast, Mr.

Li continued to sit at his desk to catch up materials.

wrote, Mr. Li feels unwell,

heart is getting more and more pain,

sweat is getting bigger and bigger,

soon, the clothes are soaked

Mr. Li asked his colleagues to call his wife

and ask his wife to drive over Pick him up to the hospital.

learned that his wife left from home.

colleagues helped Mr. Li to lie down on the sofa.

At this time,

Mr. Li’s heart pain was getting worse and worse.

and he was as uncomfortable as death. Mr. Li’s wife drove to the company downstairs

and two colleagues helped Mr. Li into the elevator

. Strong Mr. Li was afraid of delaying the progress of the project

not letting colleagues go downstairs with him

The elevator finally reached the lobby on the first floor

Mr. Li got out of the elevator with difficulty,

walked towards the door where his wife parked.

just took a few steps before

fell to the ground abruptly,

never got up again. When

waited for 120 to arrive,

had no vital signs.

After the doctor’s narration,

Mr. Li’s wife burst into tears on the spot,

was very regretful

she said, if she had cared about this point of knowledge

the child’s dad would not leave

when he deeply regretted Mr. Li’s departure

You may also ask the same question: What is the knowledge point of

?

Myocardial infarction mostly occurs on the basis of coronary atherosclerotic stenosis. Due to certain factors, the coronary atherosclerotic plaque ruptures. Platelets in the blood accumulate on the surface of the ruptured plaque to form a blood clot (thrombus) and suddenly block the coronary artery Lumen, leading to myocardial ischemic necrosis.

What should Mr. Li do after he becomes ill?

Once the patient becomes ill, try to lie down as quietly as possible, dial "120" and accept the "120" instruction to avoid random medication. What else can colleagues do before

reaches 120?

>>>2 hours

According to the pathophysiological characteristics of myocardial infarction, shortening the onset to opening the acutely occluded cardiovascular blood vessels is the core of the entire treatment process. This process is usually divided into two parts, namely, the onset of the disease to the arrival of the emergency door of the hospital and the emergency door to the opening and occlusion of the blood vessel. The second half is carried out in the hospital. Due to the current vigorous advancement of the construction of chest pain centers, the speed of first aid has basically reached the requirements of clinical guidelines. However, the first half occurred outside the hospital and there were many uncontrollable factors.

In the case of a relatively complete emergency transportation network, the pre-hospital emergency time can be controlled within 2 hours. The correct judgment and correct treatment of the first treatment site of myocardial infarction by

play a key role in the entire treatment process. This process mainly depends on the patient and bystanders, so improving the public's judgment and first aid ability is an important measure.

>>>30 minutes

The main symptom of myocardial infarction is severe chest pain, but chest pain can be caused by many reasons, other reasons include aortic dissection, pulmonary embolism, etc. For ordinary people, it is obviously unrealistic to accurately identify the cause of chest pain. Even a professionally trained doctor needs the help of a variety of auxiliary examinations. The post-treatment methods for different causes may be completely opposite, but the first-stage first aid is similar, and they are treated according to the most serious cause. Myocardial infarction is the most common cause. Usually, angina pain does not last for more than 10 minutes. If the chest pain exceeds this time, be aware of the possibility of myocardial infarction, and call "120" to send to the hospital urgently if it exceeds this time.

After the occurrence of chest pain and before the arrival of "120", personal self-help is very important for the patient's prognosis.

Regardless of the cause of chest pain, it is beneficial to reduce the patient's activity as much as possible. Avoid walking, coughing, etc., and lie down quietly and avoid frequent movement of the patient. Avoid giving the painkiller with the amount of , because most non-steroidal anti-inflammatory drugs are harmful to acute myocardial infarction. Avoid using nitroglycerin , which is usually used to treat angina pectoris, because patients with myocardial infarction are often accompanied by hypotension, and nitroglycerin may aggravate shock.

>>>Immediate cardiopulmonary recovery

Patients with severe myocardial infarction are prone to sudden respiratory and cardiac arrest. At this time, cardiopulmonary resuscitation is needed. Do not pinch people for moderately ineffective treatment. If there are bystanders, call the patient frequently to determine their consciousness. If medical personnel are present, it is necessary to determine whether there is breathing and heartbeat before deciding whether to give CPR. Ordinary people usually don't have this skill, can start cardiopulmonary resuscitation immediately after the patient suddenly becomes unconscious, and win the treatment time early.

Effective cardiopulmonary resuscitation requires chest compression depth. For example, if you are lying on a soft bed or sofa, the rescuer cannot effectively perform compressions or judge the depth of compression, so the patient should be transferred to a hard surface. High-quality cardiopulmonary resuscitation can win critical time for medical staff's first aid. If bystanders do not have CPR skills, they can seek guidance from "120", because even low-quality CPR is better than no CPR.

>>>Look for AED

A large area of ​​myocardial infarction will seriously affect the electrical activity of the heart, and some patients will experience ventricular fibrillation. Then it is necessary to use an external automatic defibrillator (AED) on the basis of cardiopulmonary resuscitation. At present, many places with heavy traffic, such as airports, shopping malls, and railway stations, have been equipped with AEDs.

AED is generally placed in a conspicuous place, usually red, marked with "AED" and other words. After the is taken off, the is turned on and the electrodes are attached according to the instructions inside, and the AED will automatically analyze whether defibrillation is needed. The machine recommends that after defibrillation, bystanders press the defibrillation button. This operation process is generally relatively simple and does not require special training.

In public places, before starting cardiopulmonary resuscitation, you should start looking for AED backup. Using AED to restore normal heart rhythm as soon as possible can protect the patient's brain function to the greatest extent. If the scene of the disease is the patient alone, should call the nearby relatives and friends as soon as possible after dialing "120", keep the phone open, and keep yourself in a position where you can be easily found.

>>>Waiting for ambulance

The car patient needs to be sent to the hospital for emergency treatment after getting sick. It is usually recommended to wait for the "120" ambulance to come. Because they respond quickly, have professional handling techniques, have first aid skills, are familiar with first aid routes, and know the appropriate hospitals for treatment. But in some special circumstances, if the ambulance cannot arrive in time or cannot arrive, bystanders can drive the patient to the hospital.

It is important to prevent patients from driving to the hospital by themselves. Because a series of driving actions may aggravate the disease itself, and the diseases that cause chest pain usually change rapidly, such as sudden loss of consciousness during driving, which may cause a car accident, which not only causes secondary injury to itself, but may also harm surrounding vehicles and people .

If there are multiple hospitals around that can be reached within the same time, try to choose a hospital with cardiac intervention capabilities. Because the most critical treatment for myocardial infarction is to open and occlude blood vessels, interventional therapy is the most preferred option at present, and primary hospitals usually do not have complete interventional therapy equipment and personnel. In addition, some critically ill patients require emergency surgery or high-level respiratory and circulatory support, which is usually not available in primary hospitals.

If the hospital with cardiac intervention capability is far away, and the patient is in critical condition, it may be delayed on the journey. can be sent to the primary hospital for thrombolysis and symptomatic supportive treatment, so as to win the transfer to a hospital with cardiac intervention capability. time.

Disease Control Lord reminds again that

time is myocardium

time is life

life distress

dial 120

today

is the sixth "National Day for Myocardial Infarction Treatment"

is set to be on November 20,

is to let people remember two "120"

is to dial 120 immediately after an acute myocardial infarction occurs!

Second, the prime time for acute myocardial infarction rescue is 120 minutes!
