Frequently Asked Questions About

Oxygen Equipment

FAQ #1

What is the difference between a resuscitator and an inhalator?   A resuscitator is used to resuscitate the non-breathing patient, the inhalator is used to give 100% oxygen to the breathing patient in distress. 

FAQ #2

What is the difference between medical grade oxygen and breathing air?  Medical grade oxygen is 100% (actually around 99.5%) oxygen.  Breathing air (and ambient air) is 21% oxygen

FAQ #3

Can I give someone too much oxygen?   It has been very difficult in finding a case in which this occurred.  This would be very rare in an emergency situation when the body is deprived of oxygen.

FAQ #4

Can I damage someone’s lungs with a demand valve?   No, demand valves have a safety relief feature, which causes them to stop building pressure at a safe level.

FAQ #5

If I try to resuscitate someone and fail, can I be sued?   To the best of my knowledge, most states have a Good Samaritan law that protects anyone who, in good faith, tries to help someone in distress.

FAQ #6

When does an oxygen cylinder have to be hydrostatically tested?    Aluminum cylinders have to be tested after 5 years.  Steel cylinders after 10 years.  They do not have to be tested until they are to be refilled. 

FAQ #7

Does oxygen have an expiration date?   Yes, the FDA (Food and Drug Administration) arbitrarily chose 5 years, but the Compressed Gas Association is fighting this rule (100% oxygen does not break down) so it is currently suspended.
