What is a common characteristic of Cheyne-Stokes respirations?

Cheyne-Stokes respirations are characterized by a cyclical pattern of breathing that includes periods of deep, rapid breaths followed by a gradual decrease in rate and depth leading to apnea, before the cycle repeats. This results in irregular breaths with fluctuations in depth. The pattern can be observed in cases of heart failure, brain injury, or during the dying process.

The irregularity of Cheyne-Stokes respirations is key to their identification, as individuals will experience varying pauses and changes in the depth of breaths rather than consistent breathing patterns. This distinguishing characteristic helps healthcare providers assess a patient's respiratory status and underlying health conditions.
