NOTE 1A Throughout this Standard, where the term “oxygen-enriched air” appears, replace it with the term
“Oxygen 93”.
[Replace the fourth paragraph with the following]
The decision to use Oxygen 93 should be made at an early stage by the medical staff of the health care
facility and is outside the scope of this Standard. The possible use of a mixture of Oxygen 93 and oxygen
is also a decision of the health care facility. The use of a supply system incorporating oxygen
concentrator(s) might require the approval of regional or national authorities.
[Replace the sixth paragraph with the following]
It is recommended that terminal units designated for oxygen be used.
