Faced with someone around me suddenly falling to the ground and breathing cardiac arrest. If we can give him cardiopulmonary resuscitation in 4 minutes, there is about half of the probability that he can save him!
Some data show that there are more and more people who have died suddenly, and they are also developing to younger.
The key skill that can successfully save their lives is to perform effective cardiopulmonary resuscitation as soon as possible.
Sadly, the popularization rate of cardiopulmonary resuscitation in my country is less than 1%, and the success rate of sudden death and rescue in my country is less than one in ten thousand.
In recent years, the country has been committed to popularizing “national first aid”. Cardiopulmonary resuscitation should not only be mastered by medical staff, but the skills that each of us must master.
If one day, the one you love to love suddenly falls in front of you, and you can do it at any time in the face of life, but if you know the heart and lung reciprocity, you may be able to save your life before 120 arrives.
The popularity of the whole people is just a few minutes, and we can master the skills of cardiopulmonary resuscitation. All of you and your family, friends, and people around you are greatly beneficial.
What is cardiopulmonary resuscitation?
Cardiopulmonary resuscitation, called CPR for short, is an extremely important first -aid skill. It is a first aid measure taken for the heart and breathing stoprs to save their lives. That is, a temporary artificial cycle is formed by pressing the heart of the chest. The electric shock defibrillation turns to the ventricular fibrillation, which promotes the heart to restore the autonomous fight, the manual respiration is correct, and the self -breathing is resumed.
How important is cardiopulmonary resuscitation? Why do everyone master?
—— Because time is life, in the first scene, you are the greatest hope that the sick person can survive, or even the only hope!
The serious consequence of the cardiac arrest is to calculate in seconds:
■ 3 ～ 5 seconds: Black Mongolia
■ 5 ～ 10 seconds: fainting, disturbance of consciousness, suddenly falling to the ground
■ About 15 seconds: convulsions, Adams-Stekes syndrome
■ 10 to 20 seconds: loss of consciousness
■ 30 to 60 seconds: the pupils are scattered
■ 60 seconds: breathing stops gradually
■ 1 to 2 minutes: pupils are fixed, two incontinence
■ 4 minutes: brain death starts
■ 5 minutes: ATP exhausted in the brain, and the energy metabolism completely stops
■ 6 minutes: Starting brain cell death, irreversible neurons injury
■ 8 minutes: “brain death”
■ Golden Time of Cardiopulmonary resuscitation: 4 ~ 6 minutes
That is, a cardiac arrest within 4 to 6 minutes is the key to success, especially within 4 minutes. Who can fight for these 4 minutes most is others (such as family, passers -by, and people).
Therefore, not only medical staff, but also everyone, including ordinary people, should learn the skills of self -rescue and mutual rescue.
Start the relationship between cardiopulmonary resuscitation time and recovery success rate:
1 minute> 90%
4 minutes> 60%
6 minutes> 40%
8 minutes> 20%
10 minutes almost 0%
That is: every 1 minute of rescue, the survival rate decreases by 10%!
Therefore, the platinum time of cardiopulmonary resuscitation is 10 minutes.
The steps and points of cardiopulmonary resuscitation
The current cardiopulmonary resuscitation mainly includes three basic first aid techniques, C-A-B, that is, the chest compression-open airway-artificial breathing. Its concise version process is as follows:
1. Confirm the safety of the scene
If it may occur in dangerous environments such as collapse and poisonous gas poisoning, move it quickly to a safe place. If it is a fire scene, or there is danger of electric shock, dangerous terrain, etc., it is not possible to implement it on the spot. It is necessary to determine the safety of the scene to rescue the scene at the scene to prevent the secondary life from expanding.
2. Judgment awareness response
Using beat the shoulders, he called closely in his ears and called: “Hey! What’s wrong with you?”.
If there is no response, it is determined to be lost consciousness.
3. Call for help
Keep calm, not panic!
Instructed others (when no one, it was it, it was it) to make a call and obtained AED (automatic body tremor).
Inform the patient where the patient is located.
4. Judgment pulse and breathing
The rescuer uses both fingers to be next to the patient’s throat 2 cm (touching the carotid artery), and at the same time observe whether the thorax is ups and downs for 5-10 seconds. During the observation process Number of seconds.
Non -professional rescuers do not need to judge patients’ breathing. Because 80%of patients with weak respiratory patients have stopped, when the patient judges unconsciously, without breathing or intermittent breathing, the chest heart compressor can be performed immediately.
5. Put the position of cardiopulmonary resuscitation
Quickly place the patient on the supine position, flatten it on the ground or hard board, unbutton the collar, and lean back.
6. Pressing position
Press the part of the two nipples to connect the midpoint (female patients are sometimes not applicable), or two horizontal fingers (lower half part of the sternum) on the sword.
Note: This kind of pressing is performed under the case of a heartbeat, and it is not implemented on people who are awake or unconscious but have no heartbeat.
7. Pressing method
In contact with the left hand palm root, the right hand overlap, the left finger tips the right hand and buckle it on it; the hands are perpendicular to the chest wall for pressing. When pressing, the upper body is leaning forward, the wrist, elbow, and shoulder joints are straight, and the hip joints are the fulcrum, and the strength of the upper body is pressed with the gravity of the upper body. Try not to interrupt as possible (the most interrupted time should not exceed 10 seconds). Depending on the pressure gap as possible, let the thoraco push back to facilitate blood flow, but do not leave the chest wall, the proportion of pressing and relaxation time is the same.
Frequency: 100 to 120 times/minute. Deep: 5-6 cm.
8. Open airway
Clean the mouth before opening the airway (bias the patient’s head to one side)
9. Artificial breathing
Auxiliary airbags can be used to use the counterpart of the mouth or simple breathing airbags.
10. Re -inspection
Determine whether the arterial movement recovers
Whether breathing recovers
The judgment time is 5 ~ 10 seconds.
Effective indicators of cardiopulmonary resuscitation
Autonomous heartbeat recovery: you can hear the heart sound, touch the artery (one of the choice of carotid artery, femoral artery, radial artery in one in the radial artery), the electrocardiogram shows sinus heart rhythm, room or border heart rhythm, even for atrocus fluttering or tremor is autonomous. The performance of heartbeat recovery.
Autonomous respiratory recovery: The thoracic losses have independent fluctuations.
Pupil changes: The scattered pupils are shrinking and smaller, and the light reflection recovers.
Oxygen improvement: The complexion of the hair, the lips, and the nails are rosy.
The brain function is resumed: the eyeballs are active and the limbs are activity.
Indicate of terminating recovery
<!-2404: First aid terminal page
Recovery success: Self -breathing and heartbeat have recovered well (some only heartbeat recovery, breathing still requires ventilator assistance), and transfer to the next stage of treatment.
Failure to recover: After more than 30 minutes of active and correct cardiopulmonary resuscitation operation, the electrocardiogram is still a straight line. The autonomous breathing and autonomous heartbeat have not been recovered. All brain stem reflection disappears. It can be judged to be clinically died. Special circumstances such as electric shock, drowning, and newborn can be extended for 1 to 2 hours.
