Abstract

For the first time ever, a device ( 1 ) for shortening the wake-up phase of an anesthetized patient (Pa) is provided. Furthermore, a process is provided for operating a device ( 1 ) as well as a process is provided for respirating a patient (Pa) with gaseous anesthetic ( 17 ).

Claims (29)

1 . A device for respirating a patient with a gaseous anesthetic, the device comprising:

a hypoventilation means for bringing about hypoventilation of the patient; and

a spontaneous breathing checking means for checking spontaneous breathing of the patient after hypoventilation has been brought about.

2 . A device in accordance with claim 1 , further comprising:

a carbon dioxide absorber; and

a switchable bypass position for said carbon dioxide absorber for bringing about hypoventilation of said patient in said bypass position.

3 . A device in accordance with claim 2 , further comprising another detector for detecting said bypass position.

4 . A device in accordance with claim 1 , further comprising a combination cartridge including a gaseous anesthetic absorber and a carbon dioxide absorber.

5 . A device in accordance with claim 4 , further comprising another detector for detecting an operational position of said combination cartridge.

6 . A device in accordance with claim 1 , further comprising preparation process means for carrying out a preparation process for preparing a wake-up phase of the patient from an anesthesia, wherein a composition of anesthetics administered can be optimized by said preparation process means.

7 . A process for operating a device for respirating a patient with a gaseous anesthetic, the process comprising the steps of:

bringing about hypoventilation of a patient; and

checking spontaneous breathing of the patient when hypoventilation has been brought about.

8 . A process in accordance with claim 7 , wherein a carbon dioxide absorber is switched into a bypass position for bringing about hypoventilation of the patient.

9 . A process in accordance with claim 8 , wherein the composition of anesthetics is optimized in a preparation step for preparation of a wake-up process.

10 . A respiration system, comprising:

a patient connection with an inspiration line and an expiration line;

a fresh gas feed including a breathing gas feed connected to said inspiration line;

a rebreathing system connected to said inspiration line and supplying a portion of breathing gas from said expiration line to said inspiration line;

a hypoventilation means for bringing about hypoventilation of a patient connected to said patient connection; and

a checking means for checking spontaneous breathing of the patient when hypoventilation has been brought about.

11 . A system in accordance with claim 10 , wherein said rebreathing system includes a carbon dioxide absorber with a bypass for fully or partially bypassing the carbon dioxide absorber in said rebreathing system and said hypoventilation means for bringing about hypoventilation of the patient changes a switching state of said bypass for fully or partially bypassing the carbon dioxide absorber.

12 . A system in accordance with claim 11 , wherein said carbon dioxide absorber in the rebreathing system includes a switchable bypass position for bringing about hypoventilation of the patient in said bypass position.

13 . A system in accordance with claim 12 , further comprising a detector for detecting said bypass position.

14 . A system in accordance with claim 12 , further comprising a combination cartridge including a gaseous anesthetic absorber and said carbon dioxide absorber, said combination cartridge being connected in said rebreathing system.

15 . A system in accordance with claim 14 , further comprising another detector for detecting an operational position of said combination cartridge.

16 . A system in accordance with claim 11 , further comprising an anesthesia administration means for administration of anesthesia to the patient.

17 . A system in accordance with claim 16 , further comprising a preparation process means for carrying out a preparation process for preparing a wake-up phase of the patient from anesthesia administration, wherein a composition of anesthetics administered can be optimized by said preparation process means.

18 . A system in accordance with claim 16 , wherein said anesthesia administration means feeds anesthesia to the patient via said fresh gas feed.
