A nasal ventilation mask having one or more attachment ports located adjacent to and overlying an upper lip of a patient when worn.

An anesthesia machine, anesthesia control method and system are provided. The anesthesia machine controls the infusion device, or the control terminal controls the anesthesia machine and infusion device, such that the doctor controls the inhalation and intravenous infusion of anesthetics for patient with only one device, without walking back and forth between multiple devices, which improves the efficiency of anesthesia control.

A control system controls fresh gas dispensing for an anesthesia device, with a patient gas-measuring unit, an anesthetic-dispensing unit, a user interface, and a fresh gas regulation unit. With a transition from deactivated assistance mode to activated assistance mode, a processing unit receives a measured signal, a fresh gas signal and an assistance signal and calculates an end tidal anesthetic concentration over time based on a current volume flow, a predefined volume flow and on a current end tidal anesthetic concentration and stores this as a preset curve. A fresh gas correction signal is output upon the determined current end tidal anesthetic concentration leaving a surrounding range of the preset curve. A predefined volume flow curve is changed as a function of the correction signal. The volume flow of fed fresh gas is increased when the surrounding range is undershot and is reduced when the surrounding range is exceeded.

Nasal tracheal devices include a tube with visual indicia of insertion depth corresponding to patient height and an inflatable cuff. The tube comprises or provides a plurality of lumens that are in fluid isolation including an airpath lumen and a pressurized fluid source for inflating the cuff. The devices may also be configured to suction patient fluid from a location adjacent and/or above the cuff.

Disclosed is a nasal ventilation mask having separate ports to monitor end-tidal CO.sub.2 expulsion integrated into the mask in order to monitor end-tidal CO.sub.2 expelled nasally or orally. Also disclosed is a CPR mask for nose-to-mouth and/or mouth-to-mouth resuscitation, having a body shaped to cover the nose and/or mouth of a victim, the mask including a CO.sub.2 absorber for eliminating at least in part rescuer's exhaled CO.sub.2 delivered to the victim.

An anaesthetic halocarbon capture system is provided. The system includes a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.
