High Fowler's position in the medical field is a way of sitting a patient up at a 90-degree angle, commonly used to improve comfort and breathing.
Step-by-step explanation:
In the medical field, the term "high Fowler's position" refers to sitting up at a 90-degree angle. This position is employed to aid a patient's breathing or comfort, particularly after surgery or during certain medical procedures. It contrasts with other positions such as lying flat on the back (supine position), lying face down (prone position), or sitting up at a 45-degree angle (standard Fowler's position).
