The CPR artificial breathing membrane is one of the key devices used for mouth-to-mouth or mouth-to-mask breathing during cardiopulmonary resuscitation (CPR). Its main components and functions include:

1. Mask part: usually made of soft and transparent material to ensure a good fit with the mouth and nose area of ​​the rescued person to prevent air leakage. The design of the mask requires that it can adapt to rescued people of different ages and sizes, from infants to adults.
2. Connection part: the pipe that connects the mask to the rescuer’s mouth device or breathing bag. This part is usually a soft plastic pipe that allows the rescuer to perform artificial respiration to the rescued person through the mask.
3. Anti-backflow valve: a device located inside the mask or on the pipe that prevents the rescued person’s exhaled air from flowing back into the rescuer’s mouth. This function is very important because it can reduce the risk of the rescuer being exposed to possible infectious diseases.
4. Mouth fitting part: the part on the mask that the rescuer uses to connect his own mouth device or breathing bag to the mask for effective artificial respiration.

The purpose of the CPR artificial breathing membrane design is to provide an effective and safe method to maintain the respiratory function of the rescued person during the first aid process. It is often included in first aid kits or professional first aid boxes to ensure that CPR can be performed immediately and necessary breathing support can be provided if needed.
