What if someone around me has a cardiac arrest?

If you find cardiac arrest, you should call the emergency number 120 immediately. In case of emergency, cardiopulmonary resuscitation should be carried out in situ after confirming the safety of the site environment. Heart disease is very serious, even affecting life safety, so if you feel uncomfortable with your heart or have other related symptoms, you should go to the hospital immediately and make effective treatment after confirming your condition. For patients with cardiac arrest, first aid must be given at the onset, otherwise it will be very dangerous.

The first aid of cardiac arrest mainly includes chest compressions, artificial respiration, application of cardiovascular active drugs and electric defibrillation. Then, let me tell you in detail how to save cardiac arrest.

1. What is cardiac arrest?

Cardiac arrest refers to the sudden stop of cardiac ejection function, the disappearance of arterial pulsation and heart sounds, and the severe ischemia and hypoxia of important organs, which leads to the termination of life. Cardiac arrest and respiratory arrest are serious heart diseases, which often occur suddenly, especially in elderly patients with weak and large-scale myocardial infarction. There will also be some complications. If the rescue measures are not appropriate at this time, it is likely to endanger the life safety of patients soon.

Second, how to rescue cardiac arrest?

1, the rescue of cardiac arrest must race against time, and cardiopulmonary resuscitation should be done immediately. Confirm the safety of the site environment, and judge the patient's consciousness. If there is no breathing pulse, start cardiopulmonary resuscitation, and make the patient lie on his back with his head, neck and trunk in a line.

2. See if there is any foreign body such as vomit in the patient's mouth, and take out the foreign body as soon as possible, so as not to affect the patient's breathing.

3. Loosen the collar and untie the belt. At the midpoint of the connecting line between the two nipples, stick the root of the left palm to the patient's chest, press vertically downward with both hands crossed and five fingers tilted, with a pressing depth of 5 to 6 cm and a pressing frequency of 100- 120 times per minute.

4. After pressing for 30 times, perform mouth-to-mouth artificial respiration twice, and so on, until the emergency personnel arrive at the scene.

Three. Effective indications for cardiopulmonary resuscitation:

1, resume spontaneous breathing

2. The scattered pupils have shrunk.

3. The systolic blood pressure of upper limbs is above 60mmHg.

4. The color of face, lips and nail bed becomes rose.

5. Clear consciousness

Fourth, how to use AED?

The AED is a automated external defibrillator, and its use method includes the following steps: turning on the power supply, placing electrode pads according to the prompts, automatically monitoring the heart rhythm, prompting defibrillation when defibrillation is needed, and pressing the defibrillation button for defibrillation.

1. Power on: After obtaining the AED, put the AED next to the patient, open the cover of the AED, insert the plug of the electrode board into the socket of the AED host, and turn on the power supply; Attention should be paid to the preparation of AED and continuous cardiopulmonary resuscitation.

2. Place the electrode sheet: unbutton the patient's clothes to ensure that the patient's chest is dry and unobstructed. Just stick the electrode pads, so that the electrode pads can fully contact the skin, and stick the two electrode pads at the corresponding positions according to the tips and labels.

3. Defibrillation: operate the AED according to the voice prompts, wait for the AED to analyze the heart rhythm, and avoid touching the patient when analyzing the heart rhythm, resulting in inaccurate analysis; After the analysis, the AED will issue a suggestion on whether to perform defibrillation, remind and confirm that everyone has not touched the patient, and then press the "discharge" button to perform defibrillation.

4. After defibrillation, if the patient has not recovered his breathing and heartbeat, he should continue cardiopulmonary resuscitation, and use AED to detect his heart rhythm again, and follow the prompts until the medical staff arrives.

At present, AED has been gradually installed in public places as emergency rescue treatment. In case of cardiac arrest or malignant arrhythmia, you can use it as mentioned above, and call 120 emergency number at the same time.

Five, the main reasons for cardiac arrest are as follows:

1, caused by heart diseases, such as coronary heart disease, rheumatic heart disease, dilated cardiomyopathy, etc. ;

2. Caused by macrovascular diseases, such as dissecting aneurysm and aortic aneurysm;

3. Caused by respiratory diseases, such as persistent asthma and lung infection. ;

4, electrolyte acid-base balance disorder;

5, poisoning, trauma and other reasons. Cardiac arrest can cause clinical manifestations such as loss of consciousness, respiratory arrest, hypothermia, dilated pupils, decreased function of various organs and even failure.

That's my introduction to how to rescue cardiac arrest. If people around you encounter such a situation, you can give first aid according to the above methods I have compiled, wait for the arrival of 120, and hand over the patient to the doctor. There are many reasons for cardiac arrest, and we need to know our own situation clearly. Generally speaking, the symptoms are similar at onset.
