The benefits of a transtracheal catheter include which of the following?

1. Lower flows are needed to obtain higher SpO2
2. The ability for the patient to eventually wean off of O2.
3. Improved self-image of the patient.
4. Oxygen cost savings of up to 60%.
a. 2 and 4 c. 1, 3, and 4
b. 1 and 3 d. 1, 2, 3, and 4

ANS: C
The guiding principle for transtracheal oxygen is that the oxygen is delivered directly into the trachea, which provides the patient with adequate oxygen while reducing the amount of oxygen used. This reduces dilution with room air on inspiration. Consequently, lower oxygen flows from the source gas are required to achieve the desired arterial oxygen saturation (SaO2) with a cost savings of up to 60%.
