The term 'transient cessation of respiration' can be summarized as apnea, which is a condition characterized by a temporary pause in breathing. Apnea can be caused by a variety of factors, including sleep disorders, respiratory infections, and even certain medications. It can also be a symptom of more serious medical conditions such as heart failure or stroke. Apnea can be dangerous if left untreated, as it can lead to oxygen deprivation and other health complications.
