Abstract

The mixing arrangement takes oxygen supplied through a mechanical adjuster (4) and a mechanical and electronic flow measuring mechanism (5 and 6). The other or second gas is supplied through an electronic flow measuring mechanism (10). The flow of the second gas is regulated by an electronically controlled regulating valve (9). A control unit (13) controls the electronic flow measuring mechanism, the electronic controlled regulator and the mechanical and electronic flow measuring mechanism. The second gas is nitrous oxide, air or a mixture of the two.
