What term describes the pattern of breathing characterized by periods of difficult breathing followed by periods of no breathing?

The term that describes the pattern of breathing characterized by periods of difficult breathing followed by periods of no breathing is Cheyne-Stokes respirations. This type of respiration is often seen in patients with certain medical conditions, particularly those affecting the brain or in terminal illness scenarios. Cheyne-Stokes respiration is characterized by a cyclical pattern where there is a gradual increase in the depth and rate of breathing, followed by a decrease that leads to a period of apnea (no breathing). This unique pattern is significant because it can indicate serious underlying health issues, necessitating further assessment and intervention.

In contrast, apnea refers solely to the absence of breathing and does not imply any preceding difficulty. Dyspnea refers to the sensation of breathlessness or difficulty breathing but does not specify the pattern or absence of breathing. Hypopnea relates to shallow or insufficient breathing without the complete cessation that occurs in apnea. Each of these terms describes different aspects of respiratory function and is not interchangeable with Cheyne-Stokes respirations.
