A pressure-operated collect valve for respiratory studies during intermittent positive pressure ventilation.
During the inflation phase of intermittent positive pressure ventilation gas is compressed in the tubes and connections between the valves of the ventilator and the patient. In machines where the valves are an integral part of the mechanism of the ventilator, and are therefore situated at some distance from the patient, the volume of gas compressed in the collecting tubes may be appreciable. Th...
متن کاملA Comparison between Nasal Intermittent Positive Pressure Ventilation and Nasal Continuous Positive Airway Pressure Ventilation in the Treatment of Neonatal Respiratory Distress Syndrome
Background: Nasal intermittent positive pressure ventilation (NIPPV) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. The present study was conducted to compare the efficacy of NIPPV and nasal continuous positive airway pressure ventilation (NCPAP) in reducing the need for intubation in preterm infants with respiratory distress syndrome (RDS)....
متن کاملA Comparative Study of Treatment Response of Respiratory Distress Syndrome in Preterm Infants: Early Nasal Intermittent Positive Pressure Ventilation versus Early Nasal Continuous Positive Airway Pressure
Background Infant respiratory distress syndrome (IRDS) is one of the main causes of serious complications and death in preterm infants. Both Nasal Continuous Positive Airway Pressure (NCPAP) and Nasal Intermittent Positive Pressure Ventilation (NIPPV) are known as the most common treatment strategies for IRDS. The present study intended to compare NCPAP and NIPPV in the treatment of preterm inf...
متن کاملDeterminants of effective ventilation during nasal intermittent positive pressure ventilation.
Our aim was to verify in healthy subjects submitted to nasal intermittent positive pressure ventilation (nIPPV) with a volumetric ventilator on controlled mode, whether changes in ventilator settings (delivered tidal volume (VT), respiratory frequency (fR) and inspiratory flow (V'I) could influence effective minute ventilation (V'E), thus allowing identification of the settings resulting in the...
متن کاملInspiratory time and tidal volume during intermittent positive pressure ventilation.
We measured the tidal volume achieved during intermittent positive pressure ventilation using various inspiratory times with a minimum of 0.2 seconds. Results indicate that tidal volume shows no reduction with inspiratory times down to 0.4 seconds. An inspiratory time of 0.3 seconds, however, is likely to reduce tidal volume by 8%, and at 0.2 seconds a 22% fall may be anticipated.
