Cheyne-Stokes respiration is a particular type of periodic breathing that is characterized by a crescendo-decrescendo pattern of breathing in between central apneas or central hypopneas (waxing and waning amplitude of flow or tidal volume).
- Cheyne-Stokes respirations are a rare irregular breathing pattern1 that typically takes place during sleep but can happen when you're awake.
- The breathing pattern consists of bursts of rapid, shallow breathing followed by slower, heavier breathing and apneic intervals, when there is no breathing at all.
- Some persons experience hypopneas, which are moments of incredibly shallow breathing, in place of an apnea2.
- The pattern resumes following an apnea or hypopnea in a cycle that normally lasts 45 to 90 seconds.
