4. The tube of claim 1, wherein said plurality of cleaning nozzles comprises said primary cleaning nozzle and secondary cleaning nozzles including said secondary cleaning nozzle, wherein a diameter of said primary cleaning nozzle is larger than diameters of said secondary cleaning nozzles.

5. The tube of claim 4, wherein said diameter of said primary cleaning nozzle is about 0.8 mm and said diameters of said secondary cleaning nozzles are about 0.5 mm.

6. The tube of claim 4, wherein said secondary cleaning nozzles are arranged in a linear fashion distally to said primary cleaning nozzle.

7. The tube of claim 4, wherein said secondary cleaning nozzles consist of three cleaning nozzles.

8. The tube of claim 1 wherein said dedicated image sensor lumen is disposed within said outer wall of said tube between said first lumen and said second lumen.

9. The tube of claim 1 further comprising a second dedicated image sensor lumen, a second image sensor and a second illumination source, the second image sensor and the second illumination source disposed in the second dedicated image sensor lumen adjacent to the open distal end of said second lumen.

10. The tube of claim 9 wherein said image sensor and said second image sensor are a CCD image sensor or CMOS image sensor.

11. The tube of claim 9 wherein said illumination source and said second illumination source are selected from the group consisting of a LED, optical fiber, waveguide, light guide, and any combination thereof.

12. The tube of claim 1 adapted for non-invasive insertion through an oral cavity or nasal cavity.

13. The tube of claim 1 adapted for insertion through an external port or incision.

14. The tube of claim 1 adapted for insertion through surgery or other invasive procedure.

15. The tube of claim 1, wherein said outer wall comprises a medial curvature with an angle from 100 degrees to 160 degrees.

16. The tube of claim 1, wherein said outer wall comprises a distal curvature with an angle from 25 degrees to 70 degrees.

17. The tube of claim 1, wherein said image sensor connector has a diameter not exceeding 10.5 mm.

18. A system adapted for respiratory intubation of a patient, said system comprising:
