What pressure will a full nitrous oxide tank read?

A full nitrous oxide tank typically reads a pressure of around 750 psi. This pressure remains relatively constant until the tank is near empty, as nitrous oxide exists as both a gas and a liquid inside the tank.

As nitrous oxide is used, the pressure gauge will show a decrease, but for a full tank, the reading is expected to be at this level. Understanding this is crucial for dental professionals using nitrous oxide in procedures, as it helps ensure that the tank is adequately filled and functioning correctly.

It's important to have accurate expectations of the pressure to aid in the safe administration of nitrous oxide during sedation. The other pressure readings listed do not reflect the standard pressure for a full nitrous oxide tank, indicating that they are not suitable for this particular situation.
