The cardiopulmonary resuscitation training model is a commonly used simulated human model in biology teaching and emergency training, used to teach students how to perform effective CPR operations. This model is typically made of durable plastic or silicone, simulating an adult's chest and head, and can simulate breathing and heartbeat. In biology teaching, CPR training models can help students learn and practice various steps of cardiopulmonary resuscitation, including correct chest compressions position, depth, frequency, and artificial respiration techniques. Through practical operation of the model, students can better understand the importance and implementation methods of cardiopulmonary resuscitation, and improve their emergency rescue abilities in emergency situations.
