Prolonged 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 کاملTime to peak tidal expiratory flow and the neuromuscular control of expiration.
The ratio of the time needed to reach peak tidal expiratory flow (tPTEF) and the duration of expiration (tE) is used to detect airflow obstruction in young children. tPTEF is decreased in patients with asthma, but knowledge about the physiological determinants of this parameter is scarce. This study examined the relationship between tPTEF and postinspiratory activities of inspiratory muscles an...
متن کاملVolume guarantee ventilation, interrupted expiration, and expiratory braking.
BACKGROUND In volume guarantee ventilation with the Dräger Babylog 8000 ventilator, inspiratory and expiratory flows are monitored and the expiratory tidal volume calculated following each inflation. The pressure for the next inflation is modified to ensure the expired tidal volume is close to the set value. AIM To investigate interrupted expiration observed during volume guarantee ventilatio...
متن کاملRelative impact of respiratory muscle activity on tidal flow and end expiratory volume in healthy neonates.
INTRODUCTION It has been suggested that infants dynamically regulate their tidal flow and end-expiratory volume level. The interaction between muscle activity, flow and lung volume in spontaneously sleeping neonates is poorly studied, since it requires the assessment of transcutaneous electromyography of respiratory muscles (rEMG) in matched comparison to lung function measurements. METHODS A...
متن کاملPeak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
