The type of breathing characterized by a prolonged expiration phase is known as asthmatic breathing. In this pattern, individuals exhibit difficulty exhaling air due to narrowed air passages, commonly resulting from conditions such as asthma. During an asthma attack or bronchospasm, the airways become inflamed and constricted, causing prolonged expiration as the patient struggles to release the trapped air in the lungs. This can lead to wheezing, a hallmark sound during expiration, as well as the sensation of breathlessness.

In contrast, Cheyne-Stokes breathing features alternating periods of deep, rapid breathing followed by periods of apnea. Biot's respirations are characterized by irregular breathing patterns, with periods of the same depth and rhythm followed by abrupt pauses. Hyperventilation, on the other hand, usually involves increased respiratory rate and depth, leading to excessive exhalation of carbon dioxide, but does not demonstrate the prolonged expiration characteristic of asthmatic breathing. Understanding these distinctions helps recognize the underlying respiratory conditions that could be affecting a patient.
