Nitrous oxide, as medical gas supply, is an inhaled gas used as pain medication, and is typically administered with 50% oxygen mix. It is often used together with other medications for anesthesia . [ 2 ]
Inhaled nitric oxide selects only pulmonary smooth muscles. There will be no effect or minimal effect of inhaled nitric oxide on atelectatic or fluid-filled lung. [3] It improves oxygenation and decreases pulmonary hypertension. [4] Nitric oxide is used together with a mechanical ventilator to treat respiratory failure in premature infants. [1]
The two general types of alternative pressure therapy are sham acupressure and the use of the P6 point. A 2015 study found no significant difference between the use of either therapy in the treatment or prevention of PONV. In a review of 59 studies, both therapies significantly affected the nausea aspect, but had no significant effect on vomiting.
Xenon is odorless (odourless) and rapid in onset, but is expensive and requires specialized equipment to administer and monitor. Nitrous oxide, even at 80% concentration, does not quite produce surgical level anaesthesia in most people at standard atmospheric pressure, so it must be used as an adjunct anaesthetic, along with other agents.
The effect is named after Bernard Raymond Fink (1914–2000), whose 1955 paper first explained it. [1] [4] When a patient is recovering from N 2 O anaesthesia, large quantities of this gas cross from the blood into the alveoli (down its concentration gradient) and so for a short period of time, the O 2 and CO 2 in the alveoli are diluted by ...
Many teens inhale nitrous oxide to feel its euphoric effects. "When enough of the drug is ingested, it can cause a short-lived high, numbness and a sense of joy or laughter," explains Mishra ...

Nitrous oxide is a colourless gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, and can thus relight a glowing splint. N 2 O is inert at room temperature and has few reactions. At elevated temperatures, its reactivity increases. For example, nitrous oxide reacts with NaNH
