Entonox cautions and contra-indications

Description: Nitrous oxide may have a deleterious effect if used in patients with an air-containing closed space since nitrous oxide diffuses into such a space with a resulting increase in pressure. Intraocular injection of gas within the past four weeks is added as a contra-indication.
