The oxygen self-rescuer is the ultimate breathing apparatus. It is suitable for any situation in which there are problems with the ambient air, as it operates independently of it. While other systems rely on a sufficient amount of oxygen in the air and only need to remove toxins from it, the oxygen self-rescuer does not require additional oxygen in the surrounding air. In theory, it is even conceivable that there is no air to breathe, for example, underwater. (However, the oxygen self-rescuer is not designed for use underwater, so this would be outside its specifications.) Due to its size, it can be carried at all times. The simplest, smallest, and lightest form of the oxygen self-rescuer works with chemically stored oxygen, which is stored in the form of KO2 granules.

The granules have two functions:

Firstly, it binds the carbon dioxide in the exhaled air and secondly, it releases oxygen in a reaction with the humidity of the exhaled air. When you breathe out, the moist exhaled air flows over the KO2 cartridge and collects in a breathing bag, which then fills. The exhaled air is then inhaled again in the same way. This is a so-called pendulum breathing. To prevent accidentally inhaling the potentially toxic ambient air, a nose clip must be worn when using the device.

The principle is based on the assumption that when you breathe harder, more oxygen is consumed. When the breathing volume increases, more moisture reaches the cartridge and more oxygen is released. It can happen that people under stress can have an increased breathing rate without actually consuming more oxygen. This means that in the long term more oxygen is released than is consumed. This can cause the breathing bag to inflate excessively. The excess air is then automatically released via a valve. Overall, the system is designed to deliver more rather than less oxygen, so that the bag is always full.
