An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system .
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] Common uses include during childbirth, following trauma, and as part of end-of-life care. [2]
An anesthetic vaporizer (American English) or anaesthetic vapouriser (British English) is a device generally attached to an anesthetic machine which delivers a given concentration of a volatile anesthetic agent. It works by controlling the vaporization of anesthetic agents from liquid, and then accurately controlling the concentration in which ...
Continuous-flow anaesthetic machine: used to provide a measured and continuous supply of gases (oxygen, nitrous oxide, etc.), mixed with a required concentration of anesthetic vapor to the patient at a required pressure and rate; video link: Anesthetic vaporizers: vaporizes the anesthetic Oxygen mask
Ketamine is the most widely anesthetic agent used for longer duration operations. After an intravenous therapy, which is about 2.2 mg/kg, mixed with the 1.1 mg/kg xylazine the half-life of xylazine is approximately 66 minutes and the clearance is around 31 mL/kg/min when patients are halothane-anesthetized.

A relative analgesia machine is used by dentists to induce inhalation sedation in their patients. It delivers a mixture of nitrous oxide ("laughing gas") and oxygen.A relative analgesia machine is simpler than an anaesthetic machine, as it does not feature the additional medical ventilator and anaesthetic vaporiser, which are only needed for administration of general anesthetics.
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
