Variability of end-expiratory lung volume in premature infants.
BACKGROUND Analysis of breath-to-breath variability of respiratory characteristics provides information on the respiratory control. In infants, the control of end-expiratory lung volume (EELV) is active and complex, and it can be altered by respiratory disease. The pattern of EELV variability may reflect the behavior of this regulatory system. OBJECTIVES We aimed to characterize EELV variabil...
متن کاملProlonged slow expiration technique in infants: effects on tidal volume, peak expiratory flow, and expiratory reserve volume.
BACKGROUND Prolonged slow expiration (PSE) is a physiotherapy technique often applied in infants to reduce pulmonary obstruction and clear secretions, but there have been few studies of PSE's effects on the respiratory system. OBJECTIVE To describe PSE's effects on respiratory mechanics in infants. METHODS We conducted a cross-sectional study with 18 infants who had histories of recurrent ...
متن کاملThe effect of surgery on lung volume and conventional monitoring parameters in ventilated newborn infants.
In newborn infants, thoraco-abdominal surgery is a serious intervention with respect to gas exchange and lung mechanics. This prospective clinical study compared surgery-induced changes in functional residual capacity (FRC) and ventilation inhomogeneity (VI) indices with changes in conventional monitoring parameters. Of 29 ventilated newborns (mean weight 2,770+/-864 g at surgery), 13, nine and...
متن کاملFluctuations in end-expiratory lung volume during Cheyne-Stokes respiration.
We hypothesized that patients with Cheyne-Stokes respiration exhibit periodic increases in end-expiratory lung volume, mediated by changes in breath components, postinspiratory inspiratory muscle activity, or both. Calibrated inductive plethysmography revealed that 12 of 12 patients with Cheyne-Stokes respiration experienced increases in end-expiratory volume during hyperpnea: maximum 412 +/- 1...
متن کاملParameters affecting the tidal volume during expiratory abdominal compression in patients with prolonged tracheostomy mechanical ventilation
[Purpose] The aim of this study was to clarify physical parameters affecting the tidal volume during expiratory abdominal compression in patients with prolonged tracheostomy mechanical ventilation. [Methods] Eighteen patients with prolonged mechanical ventilation were included in this study. Expiratory abdominal compression was performed on patients lying in a supine position. The abdomen above...
