Artificial respiration frequency is mainly the artificial respiration frequency in the process of cardiopulmonary resuscitation, for adults, the artificial respiration frequency is usually 10-12 times per minute blowing, mainly 30:2 ratio of cardiopulmonary resuscitation, that is, 30 times of compression, 2 times of respiration, the frequency of compression is 100-120 times per minute, blowing for more than 1 second. Artificial respiration should be continuous blowing, first of all, in the process of artificial respiration need to keep the patient’s airway open, that is, to exclude the patient’s oral foreign body. In the process of exhalation, the patient’s nose should be pinched first, and then breathe out, blowing with maximum force. It is very important to observe the patient’s lungs during the process of blowing to see if the artificial respiration is effective. In children, the number of artificial respirations is higher than in adults, and also in infants.
