How does life saving CPR work?

Pressing down towards the position of the heart, it should be done quickly. In this way, people can quickly wake up and save people.

1.Determine whether consciousness exists.

2.Determine whether there is a heartbeat or breathing.

3.Chest compressions 30 times.

4.Open the airway and clear the airway for the patient and straighten it.

5.Artificial respiration, 1 rescue breath every 6-8 seconds, 8-10 minutes, each breath is about 1 second.

6.Continuous CPR with a chest compression-to-rescue breath ratio of 30:27Observe the effective indications of cardiopulmonary resuscitation, consciousness, heartbeat, and circulation, and judge whether the resuscitation is successful.

8.Remove the press plate and cushion the head.

The mantra of cardiopulmonary resuscitation is seven words.

1."Call": Call the person who has fallen to the ground and see if there is a response.

2."Shouting": If the person who has fallen to the ground does not respond, he should immediately call for help and find a professional and a "life-saving device (defibrillator)" to be present.

3."Look": Look at whether the chest of the person who has fallen to the ground rises and falls, and determine whether there is sleepy breathing.

4."Pressure": If there is no breathing, cardiac compressions should be performed immediately.

5."Lifting": Lifting the chin opens the airway of the rescued person to ensure ventilation.

6."Blow": Wrap the mouth of the rescued person and blow inward twice.

7."Hit": If a defibrillator is present, it should be determined immediately if defibrillation can be performed and defibrillated as soon as possible.

Extend. The seven major indications of pulmonary resuscitation are:

1.Recovery of the pulse of the great arteries (mainly carotid artery and femoral artery rapid grasp).

2.Systolic blood pressure reaches 60 mmHg.

3.Improvement of peripheral circulation (lips, face, **, fingertips from pale, cyanosis to ruddy).

4.The dilated pupil narrows and reflexes to light are restored.

5.Spontaneous breathing resumes.

6.The patient is agitated from a coma.

7.Physiological reflexes are present.

<>1. Single ambulance:

Step 1: Lay the simulator flat and perform 30 chest compressions (30 compressions on the monitor).

Step 2: Tilt the head back 70-90 degrees to form an open airway, and blow 2 times correctly (the correct blowing on the monitor is shown as 2).

Step 3: Perform 30 consecutive correct chest compressions and 2 correct artificial breaths (i.e., 30:2) of five cycles (including one cycle of steps).

Step 4: Finally, the correct press on the monitor is displayed as 150, and the correct blow is displayed as 10. That is, the single operation is successfully operated according to the program, and then there is a voice prompt: "the operation is over", the automatically played **, the carotid artery beats continuously, the heart automatically sends out a sound of resuming beating, and the pupil is automatically reduced by the original dilation, indicating that the person is rescued.

2. Double Ambulance:

Step 1: Lay the simulator flat, and then perform double chest compressions 30 times (30 on the monitor).

Step 2: Tilt your head back 70 to 90 degrees, unblock the airway, and blow manually 2 times.

Step 3: Repeat the first.

1 and 2 operations 4 times (press 30 times to blow 2 times).

Automatic play** The carotid artery beats continuously, and the heart automatically makes a sound of resuming its beating, and the pupil is automatically narrowed by the dilatation of the original Yufeng God, indicating that the person has been saved.

At present, the new version of cardiopulmonary resuscitation operation guidelines are: C - artificial circulation (chest compressions), A - airway opening, B - artificial respiration.
