Understand and learn the knowledge and skills related to cardiopulmonary resuscitation (CPR) and trauma rescue.
These two skills can save people at critical moments. I hope everyone can learn and master the relevant skills and use them one day.
To save lives, we must first understand the symptoms that appear at different times after cardiac arrest:
15 second loss of consciousness, possibly accompanied by convulsions.
Breathing stops for 30-60 seconds and may be accompanied by urinary incontinence.
After 4 minutes, brain cells began to damage and necrosis.
4-6 minutes will cause irreversible damage to brain cells.
10 minute brain death! !
After cardiac arrest, the earlier the rescue, the higher the success rate.
The success rate of cardiopulmonary resuscitation is as high as 90% at 1 min, 50% at 4 minutes, 4-6 minutes 10%, and even after 10 minutes, most of them are vegetative.
As can be seen from the above data, the earlier the rescue begins, the better.
The operation process of cardiopulmonary resuscitation (CPR) suggests that you can learn this skill after reading this article, which will be of great help to yourself and people around you.
Ensure the safety of the site environment and do a good job of personal protection.
Judge the consciousness and breathing of the wounded and sick.
Start the first aid system (chest compression C, airway opening A, artificial respiration B)
What potential hazards need to be identified in the site environment: check whether there are any uncertain factors such as charged objects, chemicals, corrosive substances, radioactive substances, thunderstorm weather, aftershocks of building collapse after the earthquake, damaged cars, etc.
While confirming the safety of the site environment, do a good job in personal self-protection, wear masks and gloves, and wear protective clothing when necessary to avoid being stabbed by sharp objects at the site. When performing artificial respiration, use a breathing mask or face mask to prevent unnecessary infection.
If there is serious bleeding at the scene, wear protective glasses or protective covers to keep the scene ventilated.
How to judge the consciousness and breathing of the wounded and sick?
Kneel in the middle of the patient's shoulders, pat the patient's shoulders with both hands, and shout loudly in the left and right ears: "Sir/Madam, what's wrong with you, wake up!" This is to judge whether the patient is conscious.
Feel the pulse in your neck with your hands and check whether you are breathing.
Make sure that the patient is unconscious and breathing, immediately shake his arm and shout for help and explain his identity: "Someone fainted, please come quickly. I am an ambulance man of the Red Cross. Please call this gentleman with eyes 120 to reply; Please ask this gentleman in vest to bring the nearest AED (automated external defibrillator); Who else can give first aid at the scene, please come and help. "
Open the upper body clothes of the wounded and sick, and immediately perform cardiopulmonary resuscitation, chest compressions for 30 times, and artificial respiration for two times, with five groups as a cycle.
Effective compression should reach 100- 120 times per minute. The adult compression position is the connecting line between the two nipples of the patient, and the compression depth is 5-6 cm. At the same time, check the patient's condition and find that the patient is conscious. Please stop pressing it.
When giving artificial respiration, first check whether there is any foreign body in your mouth. If there are foreign objects, please take them out. After cleaning the foreign body in the mouth, give artificial respiration twice immediately.
When the sick and wounded wake up and help the patient get dressed, please give humanistic care: "You have regained consciousness, breathe, 120 will be here soon. I will wait with you, please rest assured! "
The above is the process and precautions of cardiopulmonary resuscitation, which is generally carried out with AED.
Trauma rescue mainly includes hemostasis, dressing, fixation, handling and early treatment of special injuries.
You only have one life, take precautions, master relevant skills, and remember to lend a helping hand at critical moments.
