Which term describes a pattern of abnormal breathing that includes cycles of increased and decreased depth followed by apnea?

The term that best describes a pattern of abnormal breathing characterized by cycles of increased and decreased depth followed by periods of apnea is Cheyne-Stokes respiration. This type of respiration is often observed in patients with certain medical conditions, particularly those involving severe illness or brain dysfunction.

Cheyne-Stokes respiration is typically noted with varying tidal volumes, where the patient alternates between hyperventilation and periods of no breathing at all. This pattern can occur in various clinical settings, such as in patients with congestive heart failure, stroke, or those experiencing altered levels of consciousness.

Understanding this specific breathing pattern is crucial for emergency responders, as it can indicate underlying health issues that require immediate medical intervention. Proper recognition of Cheyne-Stokes respiration can lead responders to prioritize comprehensive assessment and treatment of the patient.
