To prevent aspiration pneumonia when transporting an 86-year-old female with altered mental status, what position should she be in?

The semi-Fowler's position is recommended for this scenario because it helps reduce the risk of aspiration pneumonia, especially in individuals with altered mental status. In this position, the patient is reclined at a slight angle (typically between 30 to 45 degrees), which aids in keeping the airways open and allows gravity to help prevent any secretions or potential vomit from entering the lungs. This position promotes better lung ventilation and decreases the chance of aspiration compared to lying completely flat or in a prone position.

When dealing with an elderly patient or one with an altered mental state, their compromised ability to protect their airways makes careful positioning crucial. The semi-Fowler's position strikes a balance between comfort and safety, allowing for easier breathing and a lower likelihood of unwanted material being inhaled.
