Brain death (BD), or death by neurologic criteria, is defined by the American Academy of Neurology (AAN) as "the irreversible cessation of all functions of the entire brain, including the brain stem." 1, 2 This definition is consistent with the language used in the Uniform Determination of Death Act in 1993 3 (which is a model state law adopted by all 50 states in the United States), and . Criteria for clinical diagnosis of brain death (American Academy of Neurology)1. - If the blood pressure becomes unstable or significant oxygen desaturation and . Our prior studies found that apnea tests were aborted in 10% of patients but suggested a further decline in complications in a preliminary series. The diagno-sis of brain death was made according to the American Acad-emy of Neurology recommendations. Strong knowledge of neurophysiology and an understanding of brain death etiology must be used to confidently determine brain death. The diagnosis of brain death is a complex process. of brain death in cases where a complete brain death examination cannot be performed (for example, in a patient is too unstable to tolerate an apnea test). Apnea is one of the three cardinal findings in brain death (BD). If test is to continue, include this information in the "Comments Section" of the PreApnea Test Clinical Assessment Form. BRAIN DEATH PROGRESS NOTE The basic requirement for the declaration of brain death is the irreversible loss of cortical and brain stem activity in the adult. These movements are spinal reflexes and do not involve the brain at all.

If respiratory movements are observed, the apnea test result is negative (i.e., does not support the diagnosis of brain death). These principles can be derived from the definition of brain death provided by the Uniform Determination of Death Act (UDDA). Once brain death has been diagnosed, a patient is declared dead. Brain death determination is most commonly confirmed by clinical neurologic examination in conjunction with a positive apnea test (lack of spontaneous respiratory efforts in the presence of an elevated PaCO 2) and requires independent brain death determinations by two licensed physicians. requiring the second brain stem assessment prior to the apnea test.

Mechanisms of brain-stem death. If there is any respiratory effort then the patient isn't brain dead - reconnect to the ventilator immediately and resume supportive care. Obstructive sleep apnea is often caused by collapse of the upper airway during sleep, which reduces airflow to the lungs. In a recent publication (Wijdicks et al. 6,7 The main objective of apnea testing is to prove the absence of respiratory control system reflexes in the brainstem when intense physiologic stimulation to breathe takes place.

Sleep apnea is a sleeping disorder that can lead to serious health problems, such as high blood pressure and heart trouble, if untreated. In the event that a complete brain death examination cannot be performed, determination of death by clinical criteria alone is not possible.

Apnea testing: Apnea testing involves driving up PaCO 2levels to a maximum point to elicit the respiratory response (while supporting oxygenation). The apnea test is used to assess the brain's ability to drive pulmonary function in response to the rise of CO2.
