Which treatment is NOT suggested for barosinusitis during a flight?

1. Use of neo-synephrine

2. Ascend to a higher elevation

3. Delayed descent

4. Deep breathing exercises

The correct answer is: Deep breathing exercises

Deep breathing exercises are not suggested as a treatment for barosinusitis during a flight because this condition arises from pressure changes affecting the sinus cavities, typically when ascending or descending in altitude. Barosinusitis occurs when the sinus openings become blocked, preventing the equalization of pressure, leading to pain and discomfort. While deep breathing exercises may help in other contexts, they do not effectively address the underlying issue of pressure imbalance or blockage in the sinuses related to barosinusitis. Instead, treatments focus on relieving nasal congestion or managing pressure changes. This can include the use of medications like neo-synephrine to reduce swelling in the nasal passages, ascending to a higher elevation cautiously to promote pressure equalization, or delaying descent to allow more time for the sinuses to adapt to pressure changes.
