What should be the frequency of chest compressions for resuscitating cardiac arrest?

1. The frequency of chest compressions should be approximately 100 to 120 compressions per minute.

2. After cardiac arrest, restore the patient's spontaneous breathing and spontaneous circulation. The compression site is generally the lower 1/3 of the sternum or the midpoint of the connection between the two nipples. The compression depth should be greater than 5 to 6 cm, and the frequency is approximately 100 to 120 compressions per minute. After performing continuous compressions for about 30 times, the head-tilt, chin-lift maneuver should be used to open the airway, clear respiratory secretions, and perform two rescue breaths. Chest compressions are the primary method of establishing artificial circulation. Through chest compressions, heartbeats can be increased, allowing the heart to pump blood and maintain a certain blood flow. Through rescue breaths, vital organs such as the heart and brain can be provided with a certain amount of oxygenated blood flow. Timely chest compressions after cardiac arrest can greatly improve the patient's survival rate.

3. In the case of cardiac arrest, dial 120 immediately for medical assistance. During treatment, avoid vigorous exercise and take appropriate bed rest to prevent an increase in disease recurrence rates.
