Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Less commonly, nitrous oxide may also be safely given in a 50:50 mix with oxygen. Frequently, patients receive 100% oxygen for 5 minutes once the nitrous oxide flow diminishes. This reduces occurrences of nausea and facilitates clearing of the euphoric and other effects of the nitrous oxide gas.

Detailed explanation-2: -Nitrous oxide has a critical temperature above the room temperature, so it is stored as a liquid in pressurised cylinders, with nitrous oxide vapour present in the space above the liquid. The actual pressure of the full cylinder lies between 4400 and 5000 kPa.

Detailed explanation-3: -Nitrous oxide is more soluble than nitrogen, and its use in large concentrations is associated with the second-gas effect, diffusion hypoxia and the expansion of air-filled spaces in the body. It has analgesic effects, probably through central opioid receptor stimulation and spinal cord 2 stimulation.
