The history of CPR dummies dates back to the 1950s, when CPR technology was just beginning to develop and people realized the need for a way to train first responders. The earliest CPR dummies were relatively simple in design, mainly made of plastic or rubber, and did not have the ability to simulate real human body characteristics. However, with the advancement of technology and the emergence of medical simulators, the design and functionality of CPR dummies have been greatly improved.

In the 1960s, with the continuous development of cardiopulmonary resuscitation technology and artificial respiration technology, people began to realize that a more realistic simulator was needed to train first responders. As a result, medical simulators began to appear. These simulators can simulate the physiological characteristics of the human body, such as heartbeat, breathing, etc., making training closer to real conditions. At the same time, these simulators also have the advantages of being reusable and easy to clean, which greatly reduces training costs.

In the 1970s and 1980s, as emergency medicine continued to evolve, the design and manufacturing processes of CPR dummies were further improved. During this period, CPR dummies not only had a more realistic appearance and physiological characteristics, but also added more functions, such as adjustable blood pressure, replaceable organs, etc., making the training closer to real situations. In addition, during this period, simulators specifically used for children's cardiopulmonary resuscitation also appeared to adapt to the first-aid needs of patients of different ages.

In the 1990s and 2000s, with the development of computer technology and artificial intelligence, CPR dummies began to have more advanced functions. For example, some high-end CPR dummies can monitor the trainer's operating quality in real time through sensors and provide feedback and suggestions. In addition, some CPR dummies can also simulate different pathological conditions, such as cardiac arrest, suffocation, etc., to adapt to different first aid scenarios.

At present, CPR dummy has become one of the indispensable equipment in first aid training. CPR dummies are widely used by emergency agencies and medical institutions around the world for training in cardiopulmonary resuscitation and other first aid skills. This training method not only improves the skill level of first responders but also reduces the risk of harm to patients in real-life situations.

In the future, with the continuous advancement of technology and the continuous development of emergency medicine, the design and functions of CPR dummies will also be further improved. It is believed that through the use of more advanced CPR dummies for training and practice, the skill level of first responders will be further improved and they will make greater contributions to ensuring the safety of public life.

To sum up, the history of CPR dummies is a process of continuous development and progress. From the earliest simple plastic or rubber models to modern high-end medical simulators, the design and functionality of CPR dummies have greatly improved. In the future, with the continuous advancement of technology and the continuous development of emergency medicine, the design and functions of CPR dummies will also be further improved.
