Brain death (BD) is that someone’s brain stops functioning, even though their heart may be kept beating using a machine. After brain function had ceased, somatic function being sustained by mechanical ventilation for a long time. Further treatment is inappropriate in a dead patient. Hence, in many countries, the law provides that treatment can be legitimately removed from a patient who was diagnosed BD and the donation of organs for transplantation can start.
In conclusion, we reported two patients with a diagnosis of BD had apparently recovering breath function on the next day. However, the patient‑trigger mode of mechanical ventilation does not mean spontaneous breath. Cardiogenic oscillation may be the triggering cause. We should recognize this phenomenon and believe our determination of BD. After all, formal apnea testing is the golden standard for the absence of spontaneous respiration.
