Cardiac arrest is a sudden, life-threatening condition, which means that the heart suddenly stops beating, leading to the cessation of the blood cycle and the lack of access to oxygen and nutrients for the various organs of the body. If rescue is not carried out in a timely manner, cardiac arrest can cause the patient to die in a short period of time. This paper provides you with detailed information on the causes, symptoms, first aid methods and preventive measures.
I. Causes of cardiac arrest
The causes of cardiac arrest are diverse and common:
1 Cardiovascular diseases such as coronary heart disease, myocardial infarction and heart disorders are the main causes of cardiac arrest. These diseases affect the normal functioning of the heart, leading to abnormal cardiac electrical activity or reduced myocardial constriction, leading to cardiac arrest.
2 Respiratory system diseases: severe asthma, respiratory failure, for example, can lead to oxygen deficiency and carbon dioxide retention, affecting the normal functioning of the heart, which in turn triggers cardiac arrest.
Accidental injuries such as electroshocks, drowning, poisonings: these can lead directly to cardiac arrest, especially electric shocks, which can stop the heartbeat at short notice.
Other causes: severe physical activity, emotional emotion, overwork, etc., can also induce cardiac arrest, especially for those with heart disease themselves, which is more likely to lead to cardiac arrest.
II. Symptoms of cardiac arrest
Symptoms of cardiac arrest are evident, mainly as follows:
One sudden loss of consciousness: the patient suddenly loses consciousness and falls.
2 Respiration is stopped or abnormal: the patient’s breathing will cease or there will be abnormal breathing, such as breathing in the breath or a weak breath.
(c) 3 cardiac arrest: Touches a patient ‘ s carotid artery or femoral artery and cannot feel a pulse.
Four pupils are scattered: the patient ‘ s pupils will spread and the light reflection will disappear.
If a person is found to be suffering from the above symptoms, an immediate determination should be made as to whether the heart is stopped and the first aid should be provided as soon as possible.
III. First aid method for cardiac arrest – CPR
Cardiopulmonary resuscitation is a key measure for the rescue of patients with cardiac arrest, as follows:
1. Awareness of judgement and breathing: clapping the patient in the shoulder together to see if there is a reaction, and also to see if the patient has an ups and downs in the chest and to determine whether the breathing has stopped.
2 Call first aid personnel and get AED: If the patient loses consciousness and breathes, the first aid worker (call the local emergency call) should be immediately called and informed of the circumstances and location.
Extra chest pressure: First, the patient is placed on a solid surface, and the collar and belt are removed. The pressure is 1/3 of the mid-point of the male two nipples or the lower part of the chest. Put your hands to the chest of the patient, overlap your hands, tie your fingers to each other, stretch your arms straight and press your upper body hard. The pressure frequency is 100 – 120 times/minute and the pressure depth is 5 – 6 cm.
Artificial respiration: Clearing the alien and secretion in the mouth of the patient and keeping the respiratory tract open. Squeeze the patient’s nose with a thumb and an index finger, cover the patient’s mouth with a mouth, breathe slowly, for about one second at a time, and see if the patient’s chest is up and down. For each 30 out-of- chest pressure and 2 artificial respirations, this is repeated until the first aid worker arrives or the patient recovers his or her own breathing and heartbeat.
It is important to note that CPR is a skill that requires professional training, and if you have not received relevant training, it is recommended that, while waiting for the arrival of a first aid worker, you do your best to provide first aid in accordance with the above approach, but do not operate blindly in order to avoid secondary injuries.
IV. Preventive measures against cardiac arrest
Although heart breaks often occur suddenly, we can reduce the risk of their occurrence through a number of measures:
A healthy lifestyle: to maintain a balanced diet, a proper level of exercise, abdication of alcohol and a good mindset, which helps to prevent cardiovascular disease and thereby reduce the risk of cardiac arrest.
Control of basic diseases: For persons suffering from basic diseases such as hypertension, diabetes mellitus and haemoglobin, active control of conditions, timely medication and periodic review to reduce the risk of cardiovascular disease.
3 Periodic medical examinations: periodic medical examinations are conducted to detect potential heart diseases in a timely manner so that appropriate treatment can be taken.
Avoid overwork and emotional excitement: excessive labour and emotional excitement can induce heart failure, so care should be taken to rationalize work and life and avoid chronic stress and stress.
In short, cardiac arrest is an extremely dangerous condition, but it is possible to save patients ‘ lives if we are able to detect and take the right first aid in time. At the same time, we should also raise awareness of cardiac arrest and take effective preventive measures to reduce the risk of its occurrence. It is hoped that this presentation will make it possible to increase the number of people who know about cardiac arrest, to raise awareness and capacity for first aid and to protect their lives.
