Which position is characterized by the head of the examination table being elevated to a 90-degree angle?

The position characterized by the head of the examination table being elevated to a 90-degree angle is known as the Fowler position. This position is commonly used in medical settings for patients who require respiratory assistance or for those undergoing examinations that necessitate an elevated sitting posture. By elevating the upper body, it allows for better lung expansion and helps ease breathing difficulties, making it an important position in patient care.

In this position, the patient's back is supported adequately, providing comfort and stability while allowing healthcare providers better access for assessments or procedures. It is particularly useful for patients with heart or respiratory conditions, as it can facilitate easier airway management.

Other positions, while important in various medical contexts, do not elevate the head at this angle. For example, being prone means lying flat on the stomach, dorsal recumbent refers to lying on the back with knees bent, and the sitting position, although upright, may not necessarily be at the full 90-degree angle that characterizes the Fowler position. Thus, recognizing the details of these positions is crucial for their appropriate application in medical practice.
