Six-step formula of cardiopulmonary resuscitation

The six-step formula of cardiopulmonary resuscitation is as follows:

First, observe consciousness, breathing and heartbeat. If it disappears, press the chest again, not less than 100 times per minute, and the depth is 5~6 cm. During operation, the intermittent time should not exceed 10 second.

Perform 30 chest compressions, and then perform 2 mouth-to-mouth resuscitation. The blowing volume is about 400~600 ml.

After repeated operation for 5 times, it is necessary to observe the patient's condition. If the condition returns to normal, it is necessary to stop this behavior and stop cardiopulmonary resuscitation.

Purpose and significance of cardiopulmonary resuscitation

Objective: The purpose of cardiopulmonary resuscitation (CPR) is to maintain effective blood circulation, ensure blood supply and oxygen supply, and meet the oxygen supply and blood supply of important organs of human body through chest compressions and artificial respiration.

Significance: Cardiopulmonary resuscitation can play the role of rescue and treatment. In particular, early cardiopulmonary resuscitation can be effective within four minutes, and 50% patients with cardiac arrest can be successfully rescued. If it takes more than ten minutes, the success rate of rescue is less than 5%.

Cardiopulmonary resuscitation is very important. First of all, CPR can save lives. If the patient's heartbeat and breathing suddenly stop, this situation requires immediate cardiopulmonary resuscitation.

From a large number of research data, it is fully shown that if cardiopulmonary resuscitation can be implemented within 4 minutes, if it is effective, the survival rate of life-saving patients can exceed 50%, so cardiopulmonary resuscitation is very important, and it can save lives.

Causes of cardiac arrest

1, mainly due to arrhythmia. Many patients with coronary heart disease, myocardial infarction or heart failure died not from the primary disease, but because of the primary disease, malignant arrhythmia suddenly occurred, resulting in sudden death and loss of rescue time.

2. Severe hypoxia.

3. Changes in internal environment, such as electrolyte disorder, especially high potassium, low potassium and acidosis lead to cardiac arrest.

4, blood pressure changes, blood sugar changes, blood pressure and blood sugar slightly higher than slightly lower. Shock is a sharp drop in blood pressure, and hypoglycemia is more likely to lead to cardiac arrest.
