An apparatus for administering an anesthetic agent for a subject breathing, the apparatus comprising:
- a liquid reservoir for an anesthetic agent;
- and
- an anesthetic agent dosing unit in fluid connection with said liquid reservoir and which anesthetic agent dosing unit is connectable to an airway tube for delivering breathing gases to a subject, said dosing unit including a first member to produce anesthetic agent droplets having a diameter less than 100 μm.
A system for administering an anesthetic agent for a subject breathing, the system comprising:
- an anesthetic agent dosing unit;
- a gas analyzing apparatus;
- a user interface;
- and
- an anesthetic agent delivery controller connected to said gas analyzing apparatus for receiving measurement results and also connected to said user interface for receiving a target anesthetic agent concentration and further connected to said anesthetic agent dosing unit for controlling an anesthetic agent delivery based on received measurement results and the target anesthetic agent concentration,
- wherein said anesthetic agent dosing unit is adapted to deliver anesthetic agent droplets having a diameter less than 100 μm.
A method for administering an anesthetic agent for a subject breathing, the method comprising:
- delivering a breathing air including at least oxygen for the subject breathing;
- delivering a liquid containing the anesthetic agent;
- breaking up said liquid into droplets having a diameter less than 100 μm;
- delivering the droplets into said breathing air;
- evaporating the droplets into said breathing air;
- and
- supplying the evaporated anesthetic agent mixed with the breathing air for the subject breathing.
