NREMT Paramedic Practice

Cheyne-Stokes respirations are indeed characterized by a periodic pattern that includes cycles of increasing depth and rate of breathing followed by periods of apnea, where there is no breathing at all. This pattern creates distinct intervals where the breathing alternates between hyperpnea (increased depth and rate) and apnea (no breaths). The presence of equal intervals of apnea distinguishes this breathing pattern from others.

In contrast to regular, rapid breathing, which indicates a consistent and unchanging rate, or irregular, shallow breaths, which may vary but do not follow the Cheyne-Stokes pattern, this periodicity is a key feature of the respirations. Continuous, steady breathing lacks the variability seen in Cheyne-Stokes and therefore does not accurately describe the mechanism of this particular respiratory pattern. Understanding Cheyne-Stokes respirations is essential, as they may indicate underlying conditions such as heart failure or severe neurological issues.
