Which of the following best describes Kussmaul's breathing pattern?

Kussmaul's breathing pattern is characterized by an increased respiratory rate and depth with a regular rhythm. This type of breathing is associated with metabolic acidosis, particularly in conditions such as diabetic ketoacidosis. The body attempts to compensate for the acidotic state by hyperventilating, which helps to blow off carbon dioxide and raise the blood pH.

The deep and rapid breaths seen in Kussmaul's respirations are not irregular or shallow, which differentiates it from other respiratory patterns. In this case, the regularity of the rhythm, along with the combination of increased rate and depth, typifies Kussmaul's pattern. Understanding this pattern is crucial for recognizing and managing underlying metabolic disturbances.
