What is the semi-sitting position with the head of the bed raised 45-60° called?

The semi-sitting position with the head of the bed raised at an angle of 45-60° is known as Fowler's Position. This position is commonly used in healthcare settings, particularly in physical therapy and nursing, to facilitate breathing and improve patient comfort. When a patient is in Fowler’s Position, gravity helps in lung expansion, making it easier for them to breathe, especially in individuals with respiratory issues. It also provides a comfortable position for patients who may be experiencing pain or discomfort, allowing them to engage in conversation or eat more easily.

In contrast, the supine position refers to a person lying flat on their back, which does not offer the same benefits in terms of breathing and comfort. The Trendelenburg Position involves laying a person flat with their legs elevated, which is used in cases of shock or to promote venous return to the heart, and it is not at a semi-sitting angle. The sitting position can refer to a variety of upright postures but does not specify the elevation of the head of the bed inherently like Fowler's Position does. Therefore, Fowler's Position is the most accurate term for the described semi-sitting position.
