The contents of cardiopulmonary resuscitation include artificial respiration, chest compressions and electric defibrillation.
1, artificial respiration
The first item of cardiopulmonary resuscitation needs to confirm the identity of the patient, check whether the patient is conscious, whether his breathing and heart are working normally, and call the patient to keep him awake and whether he can clearly recognize his name and home address.
If the consciousness is vague and the heart is in a symptom state, artificial respiration can be given to the patient in time to restore the patient's spontaneous circulation and spontaneous breathing.
2. Chest compressions
When the patient loses consciousness and his heart is in a state of cardiac arrest, he should be rescued by chest compressions in time. The intensity, position and frequency of compression can be alternately performed with artificial respiration. After the rescue, if the patient is still in a coma and his heart and breathing have not improved, he can stop pressing and carry out more effective rescue methods.
3, electric defibrillation
Severe patients who have no effect on the above treatment need immediate defibrillation rescue. The high voltage and strong current of electric defibrillation can make the heart beat again. Compared with chest compression, it is a more effective rescue measure to restore the normal state of breathing and heart of patients. The three rescue measures belong to cardiopulmonary resuscitation, which are aimed at patients with cardiac and respiratory arrest.
Precautions for cardiopulmonary resuscitation:
1, determine the state of consciousness.
First of all, we must ensure whether the patient has a reaction and observe whether there is breathing and conscious activity. If the patient is unresponsive and has abnormal breathing, cardiopulmonary resuscitation should be started immediately.
Step 2 dial the emergency number
Before starting CPR, you should call an ambulance immediately and tell the patient the situation and location.
3. Correct chest compressions
Rescuers need to fold one palm on the other palm and put their fingers together. Place your palm in the center of the patient's sternum, at the nipple line. Apply enough pressure to ensure that the chest sinks at least 5 cm, and press at the rate of 100- 120 times per minute.
Between each press, let the chest fully rebound and the heart fully rebound. Try to avoid interrupting compression to maintain blood supply to the heart.
