T-Wall™
The Only Artificial Airway To Reduce Flow Resistance, Decrease Airway
Pressures and Reduce the Fatigue of Breathing in Tiny Premature Infants.
- Significantly Lowers Airway Pressures
- Significantly Lowers Flow Resistance
- Significantly Reduces the Work of Breathing
T-WALL optimizes respiratory mechanics and holds promise for a more successful
weaning from Mechanical Ventilation (MV) in premature infants. T-WALL
Ventilators to deliver gas at less pressure - A Kinder, Gentler Ventilation.
T-WALL represents a complete reengineering of the conventional endotracheal tube.
Conventional endotracheal tubes have high intrinsic resistive properties due to the high
OD/ID diameter ratio. Because of its novel design, an ultra-thin wall, coupled with a
lumen that will not deform, T-WALL offers a consistently large internal lumen and a
much lower OD/ID ratio. The result - an airway that is easier to breathe through.
Atraumatic Tip and Memory Nitinol Spring Coil
“Conventional endotracheal tubes greatly increase
the Airflow Resistance of the upper airways. This
turn can lead to a significant increase in Work of
Breathing and may necessitate the use of Assisted
Ventilation”

Note 1: The inner diameter is measured at narrowest section, the endotracheal portion. The proximal tube stage has a larger I.D.
Note 2: I.D. = Tube Inner Diameter in millimeters, O.D. = Tube Outer Diameter in millimeters.
Note 3: Airway resistance measured with standard kink bend, tube wrapped around 0.5" diameter pin. Data on file.
Note 4: Airway resistance measured with standard crushing force applied, 10 lb. Weight with 7/16" plates. Data on file.
Note 5: With standard connectors. Data on file. |
