What term describes the gradual increase and decrease in the rate and depth of respirations?

The term that describes the gradual increase and decrease in the rate and depth of respirations is Cheyne-Stokes respirations. This pattern is characterized by a cyclical progression where breathing gradually becomes deeper and faster, reaches a peak, and then gradually slows down until it eventually stops for a brief period of time. This cycle can repeat multiple times, reflecting an oscillation in respiratory patterns. It is often associated with various medical conditions, particularly those affecting the brain, such as heart failure or neurological disorders.

Understanding Cheyne-Stokes respirations is key for clinicians as it can be an important sign of underlying pathology, particularly in terminal illness. Recognizing this pattern may provide insight into the patient's condition and guide appropriate interventions.
