Which position involves the head of the bed being raised 30 to 45 degrees?

The Semi-Fowler's position involves raising the head of the bed to an angle between 30 to 45 degrees. This positioning is commonly used to enhance comfort, facilitate breathing, and promote proper alignment of the body while providing care or during rest. It is particularly beneficial for patients experiencing respiratory difficulties or those who require a slight elevation for other medical conditions.

In contrast, the High Fowler's position involves elevating the head of the bed to a higher angle, typically between 60 to 90 degrees, which is more extreme than what is required for Semi-Fowler's. The lateral position refers to lying on one side, offering a different type of support than needed with head elevation. The prone position is when a person lies flat on their stomach, which again does not involve head elevation and serves different clinical purposes.
