Légzkészülék

A légzkészülék, often translated as breathing apparatus or lung device, refers to a piece of equipment designed to assist or replace the natural respiratory function of an organism. These devices can range in complexity from simple masks that deliver supplemental oxygen to sophisticated, self-contained units that provide a breathable atmosphere in environments where it is otherwise absent.

The primary purpose of a légzkészülék is to ensure an adequate supply of oxygen to the user while also removing carbon dioxide. This can be crucial in various situations, including medical emergencies, industrial safety, diving, and space exploration. Medical légzkészülék, such as ventilators, support patients with respiratory failure, mechanically breathing for them. In industrial settings, self-contained breathing apparatus (SCBA) allows workers to operate safely in hazardous atmospheres contaminated with toxic gases or lacking sufficient oxygen.

Diving applications utilize specialized légzkészülék to enable underwater exploration by providing a portable supply of compressed air. The design and function of a légzkészülék are highly dependent on its intended use, considering factors like duration of use, environmental conditions, and the physiological needs of the user. Advancements in material science and miniaturization continue to improve the efficiency, portability, and safety of these vital devices.
