Cheyne-Stokes Respiration
A cyclic breathing pattern with apnea and crescendo-decrescendo
Definition
Cheyne-Stokes respiration is a cyclical breathing pattern characterized by periods of hyperventilation (increasing and then decreasing depth) alternating with periods of apnea lasting 5 to 30 seconds.
Causes
- Severe congestive heart failure
- Stroke and brain injury
- Uremia and metabolic encephalopathy
- End-of-life (imminent death)
- High altitude
- Opioid effect
Mechanism
Delayed feedback between pulmonary CO2/O2 changes and central respiratory drive produces the oscillation pattern, often reflects poor cerebral perfusion.
Nursing Considerations
Assess for underlying cause; treat CHF, correct electrolytes, manage ICP. In end-of-life, Cheyne-Stokes is an expected finding indicating approaching death. Reassure family that the patient is not suffering. Provide comfort measures, oral care, and a calm environment.
NCLEX Relevance
Differentiate from Biot's (chaotic, no pattern). Cheyne-Stokes is often a pre-terminal sign.
