title: [Efficiency of Pulmonary Ventilation in Remote Period After Surgery in Patients With Hronic Pulmonary Thromboembolism].
abstract: OBJECTIVE
  to assess efficiency of pulmonary ventilation in remote period after surgical treatment of chronic pulmonary thromboembolism (CPTE).
  
  
  METHODS
  We examined 29 patients with CPTE with median age 49 (38-60) years. Pulmonary ventilation was studied by body plethysmography and its efficiency was evaluated by oxygen utilization coefficient (OUC).
  
  
  RESULTS
  Comparison of OUCs before and in the remote period after surgery showed that after surgical treatment efficiency of pulmonary ventilation increased by 26% at the account of reduced hyperventilation but remained below normal. Patients age and duration of the disease had a direct impact on the baseline bronchial conductivity as well as on recovery of the respiratory system reserve in the remote period after surgery.
