Can somebody help me to decipher the second part of this sentence:

You can't use it if there's flammable anaesthetics in the presence of air/oxygen/nitrous oxide.
You can use them if there is some kind of anaesthetic which is flammable. But only when there is also oxygen air or nitrous oxide.

Because the oxygen is needed for combustion and in any other case where oxygen is not present it would likely by okay to use.

Pick one if these. They all mean the same thing but in ascending orders of simplicity

>>263104
>can't use if there's flammable anaesthetics in the presence of air
>can use if there's a flammable anaesthetic, but only if there's air

I still don't understand, these propositions look contradictive to me.

>>263099

It sounds to me like...

>You can't use the equipment for air in the presence of flammable anaesthetics
&
>You can't use the equipment for oxygen in the presence of flammable anaesthetics
&
>You can't use the equipment for nitrous oxide in the presence of flammable anaesthetics

It might help if we knew what the "equipment" is.

>>263111
No they'll only ignite in the presence of oxygen which is also present in air and nitrous oxide

>>263115
It's oesophageal probes for heart monitoring.

>>263126

Ah, right. So ignore my suggestion as I thought the "equipment" was likely to be gas delivery equipment
