[Artificial ventilation of the lungs in respiratory failure caused by lesions of the peripheral neuron].

A case with 155-day artificial ventilation of the lungs (AVL) in a patient with the poliencephalomyelitic form of tick-borne encephalitis is described. AVL was conducted through tracheostoma by the Puritan-Bennett 720ae device in the CMU mode for 26 days, then in the SIMU + PS accessory mode for 7 days, and in the CPAP + PS mode for 155 days. Despite the recovery of spontaneous respiration, vital capacity of the lungs did not normalize (1.1 liter) and the involvement at the level of the spine and the nuclei of the craniocerebral nerves was not corrected. The compensation was evidently due to training the diaphragm and the respiratory muscles and joining the accessory muscles.
