Detailed knowledge of cardiopulmonary resuscitation (CPR) simulators

Cardiopulmonary resuscitation (CPR) is an emergency procedure when the heart stops beating, so manufacturers say learning more about CPR on a daily basis can be very helpful in saving lives.

In general, cardiac arrest more than 4-6 minutes, easy to cause permanent brain cell damage, or even death. Therefore, first aid must be timely and prompt. First aid for cardiac and respiratory arrest, known as cardiopulmonary resuscitation (CPR), is usually performed by artificial external chest compression and mouth-to-mouth resuscitation. What details should we pay attention to when practicing CPR and operating a CPR simulator?

1. Mouth - to - mouth air volume should not be too large, generally no more than 1200 ml, chest slightly undulate. Blowing time should not be too long, too long will cause acute gastric dilatation, gastric flatulence and vomiting. During the process of blowing, it is necessary to observe whether the airway is unobstructed and whether the thoracic cage is blown up. If the blowing is too large or insufficient, the cardiopulmonary simulator will remind the operator that the blowing is not correct.

2. External chest heart operation can only be performed when the patient's heart has stopped beating.

3. Mouth-to-mouth blowing and chest compressions should be carried out at the same time. The operation should be carried out in strict accordance with the proportion of blowing and pressing.

4. The position of chest compressions must be accurate. Inaccuracy is easy to damage other viscera. Press the force should be appropriate, too much too hard will easily cause sternal fracture, cause pneumothorax and hemothorax; The pressure is too light, the chest pressure is small, not enough to promote blood circulation.

5. When performing CARDIopulmonary resuscitation (CPR), loosen the patient's buckles and belt so as not to cause visceral injury.

At the end of 2005, the American Heart Association (AHA) issued new CPR guidelines, which changed the frequency of compressions and breaths to 30:2 from 15:2.
