An apparatus for nasally delivering a supraglottic jet ventilation, the apparatus comprising: a. an elongated flexible tube having: i. an annular cylindrical wall defining at least one tube lumen extending substantially the entire length thereof, said cylindrical wall having external and internal surfaces and having proximal and distal ends, ii. a first catheter lumen extending lengthwise within said cylindrical wall between said external surface and said internal surface and along a dorsal region thereof, said first lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through the internal surface of said cylindrical wall adjacent the distal end thereof, iii. a second catheter lumen extending lengthwise within said cylindrical wall along a ventral region thereof, said lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through a distal face of said cylindrical wall at the distal end of said cylindrical wall; b. a first catheter extending dorsally through said first catheter lumen, said first catheter having a proximal end extending outside of said cylindrical wall through said first opening and having a distal end extending into said tube lumen through said second opening; c. a second catheter extending ventrally through said second catheter lumen, said second catheter having a proximal end extending outside of said cylindrical wall through said first opening and having a distal end extending through said second opening; and d. i. a breath sound sensor and/or pressure sensor located on the internal surface of said cylindrical wall; ii. a marker present along the external surface of said cylindrical wall, wherein said marker comprises a ruler marking and is present on the proximal portion of said tube; and wherein the presence of said marker helps determine the depth of nasal airway in the nasal cavity; and iii. a ring slidable along at least the proximal end of said elongated flexible tube or a movable stopper. a. an elongated flexible tube having: i. an annular cylindrical wall defining at least one tube lumen extending substantially the entire length thereof, said cylindrical wall having external and internal surfaces and having proximal and distal ends, ii. a first catheter lumen extending lengthwise within said cylindrical wall between said external surface and said internal surface and along a dorsal region thereof, said first lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through the internal surface of said cylindrical wall adjacent the distal end thereof, iii. a second catheter lumen extending lengthwise within said cylindrical wall along a ventral region thereof, said lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through a distal face of said cylindrical wall at the distal end of said cylindrical wall; i. an annular cylindrical wall defining at least one tube lumen extending substantially the entire length thereof, said cylindrical wall having external and internal surfaces and having proximal and distal ends, ii. a first catheter lumen extending lengthwise within said cylindrical wall between said external surface and said internal surface and along a dorsal region thereof, said first lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through the internal surface of said cylindrical wall adjacent the distal end thereof, iii. a second catheter lumen extending lengthwise within said cylindrical wall along a ventral region thereof, said lumen having a first opening through the external surface of said cylindrical wall adjacent the proximal end thereof and a second opening through a distal face of said cylindrical wall at the distal end of said cylindrical wall; b. a first catheter extending dorsally through said first catheter lumen, said first catheter having a proximal end extending outside of said cylindrical wall through said first opening and having a distal end extending into said tube lumen through said second opening; c. a second catheter extending ventrally through said second catheter lumen, said second catheter having a proximal end extending outside of said cylindrical wall through said first opening and having a distal end extending through said second opening; and d. i. a breath sound sensor and/or pressure sensor located on the internal surface of said cylindrical wall; ii. a marker present along the external surface of said cylindrical wall, wherein said marker comprises a ruler marking and is present on the proximal portion of said tube; and wherein the presence of said marker helps determine the depth of nasal airway in the nasal cavity; and iii. a ring slidable along at least the proximal end of said elongated flexible tube or a movable stopper. i. a breath sound sensor and/or pressure sensor located on the internal surface of said cylindrical wall; ii. a marker present along the external surface of said cylindrical wall, wherein said marker comprises a ruler marking and is present on the proximal portion of said tube; and wherein the presence of said marker helps determine the depth of nasal airway in the nasal cavity;
