Despite a significant improvement in the state of hemodynamics achieved during the preparation of patients for electroimpulse therapy, ventilation parameters studied 1-3 days before the procedure indicated the presence of hyperventilation: the MOV was 139% of the proper value, differing from normal values (P 0, 02). A decrease in MVL and RD was noted (up to 83.2% and 77.6%, respectively, compared to the proper level). VC, differing from normal values in absolute numbers (P 0.05), remained at a fairly high level of 89.6% in relation to VC. The residual volume as a percentage of OEL was at the upper limit of the norm (35.3%).</span></span></p>Kazan Medical archiveКазанский медицинский архив
