All are the advantages of closed circuit, except:
|B||Humidity is preserved|
|D||Less theater pollution|
a. The chief advantage of closed circuit is that the same gases can be reused so low flows are required hence becoming very economical. Since no gases are venting out so there is no theater pollution.
b. A lot of water is produced so humidity is preserved.
c. The disadvantages are that these circuit are very heavy, certain agents like trielene can produce toxic compounds with soda lime I and if it gets exhausted dangerous hypercapnia may be produced.
