“When an accident happens, it is often a matter of moments, and it takes time to save lives. With the improvement of people’s concept of first aid, many people are more or less aware of some first aid knowledge. Family Doctor Online interviewed doctors to answer some questions about “CPR“.
Who is CPR for?
Cardiopulmonary resuscitation is a life-saving technique for patients who suffer from cardiac arrest (various serious illnesses, especially cardiac serious illnesses, are prone to cardiac arrest, the most common being ventricular fibrillation, or ventricular fibrillation).
What is the procedure of CPR?
The two first aid actions often used in CPR are chest compressions and artificial respiration, but in fact, electric defibrillation is also an important part of CPR. And with the gradual popularity of automatic external defibrillator (AED), some public places will be equipped with AEDs, which will greatly improve the efficiency of resuscitation if used in a timely manner during resuscitation.
When we find a patient in need of first aid, cardiopulmonary resuscitation, then the following steps need to be carried out:
1, confirm the safety of the scene, if the patient does not respond, you should call the help of bystanders, promptly dial 120. get AED and first aid equipment, or ask bystanders to help get.
2、Check whether the patient is not breathing or just gasping for breath, and check the pulse, and observe whether the pulse can be clearly felt within 10 seconds.
3、If breathing is normal and there is a pulse, continue monitoring until emergency personnel arrive .
If there is no normal breathing and there is a pulse, artificial respiration can be given.
1,Method of artificial respiration: 1 breath every 5-6 seconds, or 10-12 breaths per minute. If the emergency response system is not activated after 2 minutes, activate the system (the standard for artificial respiration is the presence of chest heaving during ventilation).
2, Continue artificial respiration: check for a pulse approximately every two minutes. If there is no pulse, start CPR (the criteria for chest compressions are location at the midpoint of the nipple line, a depth of 5-6 cm, and a frequency of 100-120 beats per minute).
3,If there is a possible opioid overdose, give naloxone according to the treatment plan if it is available.
If there is no breathing or only wheezing with no pulse, CPR should be performed.
CPR steps: Start a resuscitation cycle of 30 compressions and two artificial respirations, and if possible an AED should be used as soon as possible.
4,After the AED arrives, the heart rhythm should be checked to see if an electric shock rhythm is available. If so, perform 1 shock and immediately continue CPR for approximately two minutes until the AED indicates the need for rhythm analysis. Continue until the advanced life support team takes over or the patient begins to move; if not, do not shock and immediately continue CPR for approximately two minutes until the AED prompts the need for rhythm analysis. Continue until the advanced life support team takes over or the patient begins to move.
After talking about the specific process of CPR, there are also areas that need attention in the CPR process.
1, the key to CPR is the timely identification and implementation of high-quality CPR, chest compressions should be standard and effective, and should not be easily interrupted.
2, chest compressions should pay attention to the strength to avoid rib fractures, sternal fractures, as well as cardiopulmonary injury, abdominal organ damage and other CPR complications.
3, after successful CPR, the rescuer also needs to observe some indicators of the patient, such as the patient’s pulse, respiration, state of consciousness, etc., while professionals also need to monitor the patient’s blood pressure, blood oxygen, electrocardiographic activity, electrolytes, acid-base, blood lactate and other indicators, and to trace the cause of the patient’s cardiac arrest.
How can the general public learn CPR?
Cardiopulmonary resuscitation is not easy to say, but not difficult to say. Previously, many people were worried that the method of first aid was too complicated for them to learn, so they did not go through specific studies. But when an accident occurs, there is no way, either can not do, or do not do.
After a simple study, the general public can also master and implement CPR. The success rate of CPR is low precisely because of the lack of timely treatment of cardiac arrest patients by first witnesses. Popularizing the knowledge of CPR and strengthening skills training is an important task for national health care. To master the correct CPR and learn the use of AEDs, it is best to attend standardized CPR classes (run by medical institutions, communities or various public interest organizations) to master the correct CPR techniques under the guidance of professionals, or you can use the Internet and videos and other forms of self-learning.
