Abstract
A combined nasal anaesthesia breathing mask and oral scavenging hood is provided herein. Such combination includes a nasal anaesthesia breathing mask with inlet means to the nasal anaesthesia mask for connection to a conventional anaesthesia breathing circuit. An oral scavenging hood is operatively associated with or is physically associatable with respect to, the nasal anaesthesia breathing mask for placement over only the mouth of the patient undergoing inhaled sedation. An inlet means is provided to the oral scavenging hood for connection to a conventional scavenging circuit. The inventive concept is that there is no gaseous communication between the nasal anaesthesia breathing mask and the oral scavenging hood. In this way, inhalation of anaesthesia gas can take place simultaneously with the scavenging of exhaled gases.
