“…An important intrinsic cause of ventilator auto‐cycling has been described in the literature, and the cause in our patient is cardiogenic oscillations. Fifteen cases have described this occurrence in the literature, as seen in Table (Harboe et al ., ; Holt, ; Ng and Tan, ; Cole, ; Wijdicks et al ., ; Bohatyrewicz et al ., ; Arbour, ; Arbour, ; France et al ., ). Cardiogenic oscillations can be seen on the ventilator waveform graphs during apnoea, and are believed to be secondary to both the cardiac volume changes and the physical movement of the heart that ensue with every contraction.…”

“…The cardiovascular state associated with terminal brain stem dysfunction can produce a high cardiac output and stroke volume and potentially cause movements of the chest or abdominal wall in phase with the cardiac cycle; this condition is termed hyperdynamic precordium. 5,13,42 Any members of the health care team involved in apnea testing should be aware of how quickly a patient's cardiovascular status can become unstable. Blood pressure may decrease from baseline to critically low levels within seconds ( Figure 3).…”

“…[26][27][28][36][37][38] Patients' movements in brain death may also be confounding factors in clinical evaluation. Possible confounding factors include spinal cord injury, movements in brain death (complex spinal reflexes, muscle fasciculations, ventilator autotriggering), therapeutic hypothermia, and transient brain stem depression after cardiopulmonary arrest 5,13,32,34,38,42,45, (Table 6). …”

“…Para o resultado satisfatório do transplante é necessário dispor de órgãos sadios, e para isso, o doador falecido, por ser um indivíduo em estado crítico, requer cuidados intensivos, afim de se manter a preservação dos órgãos, garantindo sua qualidade, até a implantação (KUNERT et al, 2011;ARBOUR, 2012).…”
