PSV has been increasingly used as a partial ventilatory support for various types of respiratory failure. We experienced premature breath termination and double triggering in a patient with ARDS during PSV, and investigated the cause of this phenomenon using respiratory muscle pressure (Pmus). ⋯ The limitation of synchronization was attributable to fixed flow termination criteria in the present PSV algorithm. When dissynchronization is not manageable, other ventilatory modes (eg, APRV, PCV) allowing spontaneous ventilation should be considered as an alternative.

Case Reports
[A case of emergency admission for CO2 narcosis in a patient with amyotrophic lateral sclerosis].
A 68-year-old man with severe dyspnea was admitted as an emergency case. He had no past history of any respiratory or neuromuscular diseases. Immediately after insufflation of oxygen, respiratory arrest occurred. ⋯ We conclude that if we meet with an emergency patient with CO2 narcosis without any pulmonary disorder, we have to suspect neuromuscular diseases, e.q. ALS. In some of such cases, mechanical ventilation supports social rehabilitation.
