AB  - Gas exchange and pulmonary mechanics in high frequency-jet ventilation (HFJV) 
      were studied during intubation anesthesia in patients with normal respiratory 
      organs. The HFJV frequency ranged from 100 to 400 per minute. The tidal volumes 
      (VT) varied from 50 to 140 ml. Gas exchange was studied in 11 patients, the total 
      number of regimens amounting to 69. The physiological dead space volume (VD) was 
      determined by the Bohr method for different combinations of VT and frequency 
      after 15-minute ventilation with each regimen. The values of VD and VA were found 
      to have linear relationships with VT and no relation to the ventilation 
      frequency. Linear regression equations were derived for these relationships. The 
      dynamic pulmonary distension in HFJV was assessed in 9 patients using the 
      interrupted HFJV techniques, up to 28 regimen being tested for each patient. An 
      exponential relationship between the accumulated gas volume and VT was found at 
      fixed frequency values and duration of the expiratory phase. The regimen capacity 
      for inducing gas accumulation in the lungs is determined by the ratio of 
      ventilation frequency to the expiration time (accumulation coefficient). The 
      dynamic pulmonary distention in HFJV is attended with a rise in mean respiratory 
      pressure which, however, remains lower than the mean alveolar pressure. The 
      obtained evidence should be taken into account when choosing an optimal regimen 
      for individual HFJV.
