Abstract: A detection system and method comprising a proximal end that connects to a ventilating device, a distal end that connects to a ventilating tube, a lumen between the proximal end and the distal end, a housing surrounding the lumen that couples the proximal end and the distal end, wherein at least a portion of the housing is transparent, and at least one detection element at least partially exposed to gases in the lumen, whereby continuously monitoring the proper positioning of the ventilating tube in an airway.

Abstract: A ventilation system and method with a ventilating tube, a stylet removably disposed within the ventilating tube, and a proximal housing. A proximal housing includes a proximal end that connects to the ventilating tube, a distal end that connects to a ventilating machine, a lumen between the proximal end and distal end, an external wall between the proximal end and distal end, a filter contained within the external wall, surrounding the lumen, and connecting the proximal end and distal end, and a cavity between the filter and the external wall. A proximal housing contains at least one detection element and can be sensitive to carbon dioxide. The same proximal housing contains at least one treatment element to heat, cool, humidify, dehumidify, or provide medication to the lumen of the proximal housing.
