In today's world, Lambertsen Amphibious Respiratory Unit is a topic that has gained great relevance and interest. Its impact has been felt in different aspects of society, from politics to popular culture. In this article, we will explore in detail the different nuances and perspectives surrounding Lambertsen Amphibious Respiratory Unit, analyzing its influence on the modern world and its role in shaping contemporary mindsets and dynamics. Through an exhaustive and multidimensional analysis, we aim to shed light on this topic and understand its importance in the current context. Additionally, we will examine possible future implications and possible avenues to address the challenges that Lambertsen Amphibious Respiratory Unit presents in our ever-changing world.
The Lambertsen Amphibious Respiratory Unit (LARU) is an early model of closed circuit oxygen rebreather used by military frogmen. Christian J. Lambertsen designed a series of them in the US in 1940 (patent filing date: 16 Dec 1940) and in 1944 (issue date: 2 May 1944).
The LARU is what the initials SCUBA (Self-Contained Underwater Breathing Apparatus) originally meant; Lambertsen changed his invention's name to SCUBA in 1952; but later "SCUBA", gradually changing to "scuba", came to mean (first in the USA) any self-contained underwater breathing apparatus. (Modern diving regulator technology was invented by Émile Gagnan and Jacques-Yves Cousteau in 1943 and was not related to rebreathers; nowadays the word SCUBA is largely used to mean Gagnan's and Cousteau's invention and its derivatives.)
Lambertsen designed the LARU while a medical student and demonstrated the LARU to the Office of Strategic Services (OSS) (after already being rejected by the U.S. Navy) in a pool at the Shoreham Hotel in Washington D.C. in 1942 The OSS "Operational Swimmer Group" was formed and Lambertsen's responsibilities included training and developing methods of combining self-contained diving and swimmer delivery including the LARU.
Many diving rebreathers are descended from it. However, there were earlier underwater uses of rebreathers:
